azure data factory get metadata recursively

Navigate to the Azure ADF portal by clicking on the Author & Monitor button in the Overview blade of Azure Data Factory Service.. In the case of a blob storage or data lake folder, this can include childItems array – the list of files and folders contained in the required folder. The Azure Data Factory GetMetadata activity now supports retrieving a rich set of metadata from the following objects. On the New data factory page, enter a name for your data factory. Share: If you found this article useful interesting, please share it – and thanks for reading! What I really need to do is join the arrays, which I can do using a Set variable activity and an ADF pipeline join expression. In the case of a blob storage or data lake folder, this can include childItems array – the list of files and folders contained in the required folder. I have a metadata activity to get the files in one of my azure data factory pipeline and its linked to a data lake. You can copy data from the following data stores to Azure Data Lake Store: [!INCLUDE data-factory-supported-sources] [!NOTE] Create a Data Lake Store account before creating a pipeline with Copy Activity. We used Azure Data Factory service to ingest, transform and load the data while adding complex logic to prevent having to run a cluster every day and thus, saving money. Copy activity with supported source/sink matrix 2. Check out part one here: Azure Data Factory – Get Metadata Activity; Check out part two here: Azure Data Factory – Stored Procedure Activity; Check out part three here: Azure Data Factory – Lookup Activity; Setup and configuration of the If Condition activity. Before we start authoring the pipeline, we need to create the Linked Services for the following using the Azure Data Factory Management Hub section. Once debug completes you can now take a look at the output of the debug execution for any of the activities in your pipeline. By using the Until activity I can step through the array one element at a time, processing each one like this: I can handle the three options (path/file/folder) using a Switch activity – which a ForEach activity can contain. Azure Data Lake Store gen2 (ADLS gen2) is used to store the data from 10 SQLDB tables. Solution can also read the CDM manifest recursively … Now that the activity has been configured, it’s time to run it in debug mode to validate the output parameters. I don’t know when this option was added, but if you open the Get Metadata Activity you will find under Dataset the option Field List . 3. For now, let’s take a look at the basic pattern: This pattern can be broken down into three basic parts. You can use it in the scenarios of validating the metadata information of any data, or triggering a pipeline when data is ready. Azure Data Factory is an amazingly powerful tool that can accomplish just about every ETL/ELT task. Furthermore, at various community events I’ve talked about bootstrapping solutions with Azure Data Factory so now as a technical exercise I’ve rolled my own simple processing framework. Spark is better than Data Factory. Hi Team, I am using Azure File Storage as source. Create Data Factory using Arm Template. ( Log Out /  Select Integration, and then select Data Factory. You can use the Get Metadata activity to retrieve the metadata of any data in Azure Data Factory. With the Get Metadata activity selected, complete the following tasks: Click on Dataset in the property window. The path represents a folder in the dataset's blob storage container, and the “Child Items” argument in the field list asks Get Metadata to return a list of the files and folders it contains. In this, it uses the business/technical/operational metadata as input and creates a model.json using the jsonschema of CDM. Azure data factory is copying files to the target folder and I need files to have current timestamp in it. Azure Data Factory (ADF) v2 Parameter Passing: Putting it All Together (3 of 3): When you combine a Salesforce filter with a parameterized table name, the SELECT * no longer works. The other two switch cases are straightforward: Here's the good news: the output of the “Inspect output” Set variable activity. The result correctly contains the full paths to the four files in my nested folder tree. It would be helpful if you added in the steps and expressions for all the activities. Select any other properties you would like to get information about. The path prefix won't always be at the head of the queue, but this array suggests the shape of a solution: make sure that the queue is always made up of Path → Child → Child → Child… subsequences. And sure, I accept for this specific situation it certainly is. Maximize the business value of SQL Server data. At the end of the course, students will be able to get started and build medium complex data driven pipelines in data factory independently and confidently. In a previous post (Lookup activity), we discussed Lookup activity to read the content of the database tables or files.ADF also has another type of activity: Get Metadata activity, which allows reading metadata of its sources. But that will come after we cover the basics! How to reference output parameters from the Get Metadata activity. The Azure services and its usage in this project are described as follows: Metadata store is used to store the business metadata.In this project, a blob storage account is used in which the data owner, privacy level of data is stored in a json file. “_tmpQueue” is a variable used to hold queue modifications before copying them back to the “Queue” variable. So lets get cracking with the storage account configuration. In this post you are going to see how to use the get metadata activity to retrieve metadata about a file stored in Azure Blob storage and how to reference the output parameters of that activity. That's the end of the good news: to get there, this took 1 minute 41 secs and 62 pipeline activity runs! Azure Data Factory is flexible enough and I can accomplish this with the following expression: @array(item()) My sub-pipeline accepts this array parameter value and does further JSON data … So I can't set Queue = @join(Queue, childItems)1). Part 2 of 4 in the series of blogs where I walk though metadata driven ELT using Azure Data Factory. childItems is an array of JSON objects, but /Path/To/Root is a string – as I've described it, the joined array's elements would be inconsistent: [ /Path/To/Root, {"name":"Dir1","type":"Folder"}, {"name":"Dir2","type":"Folder"}, {"name":"FileA","type":"File"} ]. So we have some sample data, let's get on with flattening it. I do not get the folder items. As always, thanks for checking out my blog! The following functionality is available in the control flow: You can use the output from the Get Metadata activity in conditional expressions to perform validation. A cross tenant metadata driven processing framework for Azure Data Factory and Azure Synapse Analytics achieved by coupling orchestration pipelines with a SQL database and a set of Azure Functions. Solution: 1. Get Metadata activity and the ForEach activity. Next, I am going to set up and configure the activity to read from a file I have in Azure Blob storage. But since its inception, it was less than straightforward how we should move data (copy to another location and delete the original copy).. What's more serious is that the new “Folder” type elements don't contain full paths – just the local name of a subfolder. The Until activity uses a Switch activity to process the head of the queue, then moves on. To use a Linux file share, install Sambaon your Linux server. Next, I am going to set up and configure the activity to read from a file I have in Azure Blob storage. For example, @activity(‘Get Metadata1’).output.Last Modified won’t work because Last Modified is the incorrect name of the output parameter, so the challenge now is figuring out what that output parameter name is so you can use that somewhere else in your pipeline. For four files. The Switch activity's “Path” case sets the new value CurrentFolderPath, then retrieves its children using Get Metadata. recursive: Indicates whether the data is read recursively from the sub folders or only from the specified folder. At the moment, SharePoint is not supported as a data source in Azure Data Factory (ADF), the cloud-based data integration service by Microsoft. (Don't be distracted by the variable name – the final activity copied the collected “FilePaths” array to “_tmpQueue”, just as a convenient way to get it into the output). This video shows how to use the Get Metadata activity to get a list of file names. Thanks! Currently, Data Factory UI is supported only in Microsoft Edge and Google Chrome web browsers. This suggestion has a few problems. Easily discover and govern all your SQL Server data with a unified data governance service. It is a common practice to load data to blob storage or data lake storage before loading to a database, especially if your data is coming from outside of Azure. Welcome to part one of a new blog series I am beginning on Azure Data Factory. In this post you are going to see how to use the get metadata activity to retrieve metadata about a file stored in Azure Blob storage and how to reference the output parameters of that activity. I've given the path object a type of “Path” so it's easy to recognise. You can use it in the scenarios of validating the metadata information of any data, or triggering a pipeline when data is ready. But that's another post…. from an Azure Function), it is possible to implement Google Analytics extracts using ADF's current feature set. If you want all the files contained at any level of a nested a folder subtree, Get Metadata won't help you – it doesn't support recursive tree traversal. However, a dataset doesn't need to be so precise; it doesn't need to describe every column and its data type. The only thing I needed to do get my previous output back was adding structure as an argument. Solution utilize Azure data factory pipelines and Azure function based on CDM SDK to copy SQL tables data and generate CDM metadata to Azure storage account. Copying files using Windowsauthentication. Azure Data Lake Gen 1. Each Child is a direct child of the most recent Path element in the queue. The metadata structure from Data Factory . The following attributes can be copied along with files: All customer-specified metadata. Change ), You are commenting using your Google account. In fact, I can't even reference the queue variable in the expression that updates it. A workaround for nesting ForEach loops is to implement nesting in separate pipelines, but that's only half the problem – I want to see all the files in the subtree as a single output result, and I can't get anything back from a pipeline execution. 2. First, I am going to create a new pipeline and then add the Get Metadata activity to the pipeline. Change ), You are commenting using your Facebook account. Welcome to part one of a new blog series I am beginning on Azure Data Factory. Give it a name and set variable i as follows. If you want all the files contained at any level of a nested a folder subtree, Get Metadata won't help you – it doesn't support recursive tree traversal. The folder at /Path/To/Root contains a collection of files and nested folders, but when I run the pipeline, the activity output shows only its direct contents – the folders Dir1 and Dir2, and file FileA. This expression will check whether or not the Last modified field obtained from the previous activity falls within last 7 days period: Furthermore, at various community events I’ve talked about bootstrapping solutions with Azure Data Factory so now as a technical exercise I’ve rolled my own simple processing framework. Time to get back to Azure Data Factory UI to set up the last mile our work here, I mean, the work of copying data from the RDS MySQL into a SQL Database. ( Log Out /  This is not the way to solve this problem . ( Log Out /  when every file and folder in the tree has been “visited”. I also want to be able to handle arbitrary tree depths – even if it were possible, hard-coding nested loops is not going to solve that problem. 1) To get metadata of our sourcing folders, we need to select "Child Items" for the output of our [Get Metadata] activity task: Which provides a list of sub-folders and files inside the given folder with a … SQL Server table, SAP Hana table, Teradata table, Oracle table) essentially any Dataset available in Azure Data Factory… mpearson@pragmaticworks.com. Save the file. Azure blob storage - get metadata for a blob does not get the custom metadata that is set by the user. Take a look at the below design pattern: In this blog post you are specifically going to learn the following three items: First, I am going to create a new pipeline and then add the Get Metadata activity to the pipeline. If the data is already prepared or requires minimal touch, you can use ADF to transport your data, add conditional flows, call external sources, etc. I don’t know when this option was added, but if you open the Get Metadata Activity you will find under Dataset the option Field List . Data Factory can be a great tool for cloud and hybrid data integration. Factoid #1: ADF's Get Metadata data activity does not support recursive folder traversal. - mrpaulandrew/procfwk A better way around it might be to take advantage of ADF's capability for external service interaction – perhaps by deploying an Azure Function that can do the traversal and return the results to ADF. create a queue of one item – the root folder path – then start stepping through it, whenever a folder path is encountered in the queue, use a. keep going until the end of the queue – i.e. Lookup activity 3. Connect it with the Success (green) end of Get Metadata activity. Now, Data Factory has recently taken a massive step forwards to being a true ETL tool with the annoucment of Azure Data Factory Data Flows. We can make use of the “lookup activity” to get all the filenames of our source. I can start with an array containing /Path/To/Root, but what I append to the array will be the Get Metadata activity's childItems – also an array. Factoid #5: ADF's ForEach activity iterates over a JSON array copied to it at the start of its execution – you can't modify that array afterwards. For candidates who are planning to give DP 200 certification: Implementing Azure Data Solution, this course covers the topics related to Azure Data Factory. Enter the blob storage connect string and trigger scope. The default trigger type is Schedule, but you can also choose Tumbling Window and Event: Let’s look at each of these trigger types and their properties :) In this first post I am going to discuss the get metadata activity in Azure Data Factory. If it's a file's local name, prepend the stored path and add the file path to an array of output files. Please note, for this post I assume you know how to create a dataset in Azure Data Factory. Hey Brett, I don’t quite understand the question. We only have the one activity in this example. Be sure to check out the other blogs in this series to get a better understanding of how to use use the output parameter in other activities. Access Data Factory in more than 25 regions globally to ensure data compliance, efficiency, and reduced network egress costs. Mitchell, Great Post – do you know lastModified would show “lastModified”: “2018-10-08T07:22:45Z for a file uploaded on 12‎/‎17‎/‎2018‎ ‎7‎:‎38‎:‎43‎ ‎AM CST? Azure Data Factory copy activity now supports preserving metadata during file copy among Amazon S3, Azure Blob, and Azure Data Lake Storage Gen2. The list contains 'files' and 'folders' - the 'folders' in the list is causing an issue in later processing. Connect securely to Azure data services with managed identity and service principal. Welcome to part one of a new blog series I am beginning on Azure Data Factory. Would you like to email me? Copying files as-is or parsing/generating files with the supported file formats and compression codecs. File or folder metadata in the file storages of: Azure Blob storage; Azure Data Lake Store; Azure Files Iterating over nested child items is a problem, because: Factoid #2: You can't nest ADF's ForEach activities. The only thing I needed to do get my previous output back was adding structure as an argument. Note when recursive is set to true and sink is file-based store, empty folder/sub-folder will not be copied/created at sink. Factoid #3: ADF doesn't allow you to return results from pipeline executions. Let's recreate this use case in our Azure Data Factory pipeline. However, not all is lost, you will find that referencing these output parameters is not that difficult and they have a basic pattern you can work with. On that basis and using my favourite Azure orchestration service; Azure Data Factory (ADF) I’ve created an alpha metadata driven framework that could be used to execute all our platform processes. Spoiler alert: The performance of the approach I describe here is terrible! Select the property Last Modified from the fields list. what specific name do you use to call that parameter? The revised pipeline uses four variables: The first Set variable activity takes the /Path/To/Root string and initialises the queue with a single object: {"name":"/Path/To/Root","type":"Path"}. Is this exepcted behaviour. The Azure Data Factory GetMetadata activity now supports retrieving a rich set of metadata from the following objects. On that basis and using my favourite Azure orchestration service; Azure Data Factory (ADF) I’ve created an alpha metadata driven framework that could be used to execute all our platform processes. It is possible with Azure Data Factory V2. This will get file size, row count, … First, click Triggers. For more clarification regarding “Lookup activity” in Azure Data Factory, refer to this documentation. :D. Open up a pipeline, click the copy data activity, and go to the user properties. Last Modified is going to be lastModified and the final code to reference the output parameter will look like the following: @activity(‘Get Metadata1’).output.lastModified. Delete activity Specifically, this file system connector supports: 1. By: Fikrat Azizov | Updated: 2019-11-28 | Comments (5) | Related: More > Azure Data Factory Problem. You can get the specific name of the output parameters by taking a look at the output results of the Debug operation. Change ), You are commenting using your Twitter account. We used Azure Data Factory service to ingest, transform and load the data while adding complex logic to prevent having to run a cluster every day and thus, saving money. Data Factory can be a great tool for cloud and hybrid data integration. The files and folders beneath Dir1 and Dir2 are not reported – Get Metadata did not descend into those subfolders. Subsequent modification of an array variable doesn't change the array copied to ForEach. I’m simply calling that out as it might not be obvious to everyone A quick example from my playing around: The actual dataset as seen in Notepad++. Hi, I am using recursive file copy to copy text files within Azure Datalake and it works completely fine. Click Build your own template in editor. In recent posts I’ve been focusing on Azure Data Factory. Select your dataset from the dropdown, or create a new one that points to your file. Scan your SQL Servers at no extra cost. I have both Folders and Files in the Azure File Storage Folder. Factoid #7: Get Metadata's childItems array includes file/folder local names, not full paths. You could maybe work around this too, but nested calls to the same pipeline feel risky. If … This is exactly what I need, but without seeing the expressions of each activity it's extremely hard to follow and replicate. In this first post I am going to discuss the Get Metadata activity in Azure Data Factory. Storage Account Configuration Lets start off with the basics, we will have two storage accounts which are: vmfwepsts001 which is the source datastorevmfwedsts001 which is the… The workaround here is to save the changed queue in a different variable, then copy it into the queue variable using a second Set variable activity. [ {"name":"/Path/To/Root","type":"Path"}, {"name":"Dir1","type":"Folder"}, {"name":"Dir2","type":"Folder"}, {"name":"FileA","type":"File"} ]. This is a limitation of the activity. At the time of writing, Azure Data Factory has no connector to enable data extraction from Google Analytics, but it seems to be a common requirement – it has 594 votes on ADF's suggestions page, making it the sixth most popular idea there.. With a bit of help (e.g. Creating the element references the front of the queue, so can't also set the queue variable – a second, This isn't valid pipeline expression syntax, by the way – I'm using pseudocode for readability. Factoid #8: ADF's iteration activities (Until and ForEach) can't be nested, but they can contain conditional activities (Switch and If Condition). The name of the Azure data factory must be globally unique. (I've added the other one just to do something with the output file array so I can get a look at it). This is inconvenient, but easy to fix by creating a childItems-like object for /Path/To/Root. Take another look at the output results and you will see the exact name needed for the output parameter reference. It is not listed as a supported data store/format for the Copy Activity, nor is it listed as one of the possible connectors. If it's a folder's local name, prepend the stored path and add the folder path to the, “CurrentFolderPath” stores the latest path encountered in the queue, “FilePaths” is an array to collect the output file list. In this post I try to build an alternative using just ADF. Click on the output to see the output values for the items selected: Tip: If you don’t see the output of the debug operation, click in the background of the pipeline to deselect any activities that may be selected. SQLToLake V2 is a generic sample solution to export SQLServer (on-premise or Azure SQL) tables data to Azure Data lake Gen 2 storage account in Common data model format. You don't want to end up with some runaway call stack that may only terminate when you crash into some hard resource limits . Select the property Size from the fields list. For more information, see Get started with Azure Data … Azure Data Factory (ADF) v2 Parameter Passing: Putting it All Together (3 of 3): When you combine a Salesforce filter with a parameterized table name, the SELECT * no longer works. azure data factory foreach file in folder, Using a 'Get Metadata' component I have successfully retrieve a list of "files and folders" from an on-premise folder. Example: SourceFolder has files --> File1.txt, File2.txt and so on TargetFolder should have copied files with the names --> File1_2019-11-01.txt, File2_2019-11-01.txt and so on. Get Metadata to retrieve info of all files in a folder; do NOT retrieve contents I am deeply shocked to discover that "Get Metadata" activity, when used with File System dataset, actually retrieves the contents of all the files in a folder just to display the file names without even lastModified date PER FILE in the end. You could use a variable to monitor the current item in the queue, but I'm removing the head instead (so the current item is always array element zero). “Default” (for files) adds the file path to the output array using an, “Folder” creates a corresponding “Path” element and adds to the back of the queue. In this video, Frank Liu shows how to use the Get Metadata activity to get … For example, do you want to retrieve the Last Modified date or the Size? Azure Function Python is used by Azure Data Factory to create a single metadata file adhering to the Common Data Model (CDM) format. It is a common practice to load data to blob storage or data lake storage before loading to a database, especially if your data is coming from outside of Azure. Unfortunately this part is not complete, now you have to specify exactly which output parameter you want, and you have to figure out how to call that parameter. (OK, so you already knew that). How to edit the query for Edit TOP 200 Rows in Management Studio (SSMS), Quick Tips - Export data from Power BI using R, Azure Data Factory–Executing an ADF Pipeline from Azure Logic Apps. Azure Data Lake architecture with metadata. Today I’d like to talk about using a Stored Procedure as a sink or target within Azure Data Factory’s (ADF) copy activity. I'm sharing this post because it was an interesting problem to try to solve, and it highlights a number of other ADF features. For this blog, I will be picking up from the pipeline in the previous blog post. Allowed values are: true (default), false: No: maxConcurrentConnections Trigger a pipeline when data is ready/available. In any case, for direct recursion I'd want the pipeline to call itself for subfolders of the current folder, but: Factoid #4: You can't use ADF's Execute Pipeline activity to call its own containing pipeline. In the Let’s get Started page of Azure Data Factory website, click on Create a pipeline button to create the pipeline.
