Matillion software deployment scenario we are following, that means: The data engineers and data scientists only commit artifacts that they have changedThe DevOps pipeline runs for every commitIn a Matillion ETL context, the DevOps pipeline deliberately targets only the changes that involve the Matillion ETL codebaseGathering and committing the changed artifacts is done using the Matillion ETL REST API, as we saw in the previous section. With Azure DevOps you can easily make a pipeline run upon every commit. You choose the name of the GitHub event that should trigger the workflow by setting the "on" element in the root map. In our worked example, it looks like this:name: Build and Deploy Matillion ETL appon: push: branches: - masterMatillion's REST API generates JSON files for the job definitions. Within the workflow, it's not difficult to isolate the changes by checking out the entire repository into the runner, and then using a git metadata query. Our implementation does as follows: # Checkout the repo so the workflow can access it - name: Sync repository uses: actions/checkout@v2 with: fetch-depth: 0 # List the changed files - name: List changed run: | git diff --diff-filter=AM --name-only ${{ github.event.before }}..${{ github.event.after }}A section of the event stream from a full deployment run is shown below. It only contains a single Matillion ETL job: In summary, the DevOps workflow has determined that only one Matillion job was changed, so that's the only one that needs to be replaced on the target Matillion ETL instance. This last best practice focuses on making sure the DevOps process only involves aspects of the solution that have been changed. This approach enables you to start small and scale later as the project requires. It's highly targeted and quick to run. This is a vital enabler for the early and continuous delivery of valuable software. Next stepsThis article has focused on best practices for managing Azure DevOps CI/CD Pipelines using one specific technique with Matillion ETL. As next steps, you might consider taking advantage of more sophisticated features such as:ApprovalsAdding more Azure service deployments, for example to integrate with Azure Queue Storage and the corresponding Matillion ETL functionalityAdding pipelines to your Azure Boards as part of agile project managementIntroducing Exploratory & Manual TestingVisiting the CI/CD solution ideas area in the Azure documentationDownloadsFor reference, you can download the full GitHub workflow script that we have been using.Integrate Matillion ETL with the Of standard libraries installed. Additionally, and frequently, Matillion ETL users may want to install additional Python libraries on their Matillion ETL instances. This can be done using pip, Python's package manager. Read Additional Modules to learn how to add Python libraries to a Matillion ETL instance.As of version 1.61.6, Matillion ETL comes with version 8.1.2 of pip for Python2 and version 9.0.3 of pip for Python3. Typically, the version of pip that ships with Matillion ETL should be sufficient for most use cases and we do not recommend updating the version of pip. Matillion ETL releases are tested based on the version of pip that is included with Matillion ETL. Installing a different version of pip could result in unexpected behavior within Matillion ETL. If you find a need to upgrade the version of pip on your Matillion ETL instance, please ensure you have a current backup of your instance that can be restored if necessary.Migrating Matillion InstancesThere can be many reasons to launch a new Matillion ETL instance and migrate your existing Matillion ETL instance over to it. The most common scenario for this is when updating to a new version of Matillion ETL following our recommended best practice to launch a new Matillion instance and then use Matillion's Migrate feature. When migrating, note that Python libraries are included in the list of resources that are not automatically migrated. We will outline here the best practice steps for migrating Python libraries that your Matillion ETL jobs may have dependencies on, to a new Matillion ETL instance.Confirm versions of Python and Pip on the CURRENT Matillion ETL instance.SSH on to the Matillion instanceRun the following commands and note the output:Current version of Python2 installed: sudo python --versionCurrent version of Pip installed for Python2: sudo pip --versionCurrent version of Python3 installed: sudo python3 --versionCurrent version of Pip installed for Python3: sudo pip3 --versionConfirm the Python Libraries installed and the version of each on the CURRENT Matillion ETL instance.SSH on to the Matillion instanceRun the following commands and note the output:List of installed Python2 libraries: sudo pip freezeList of installed Python3 libraries:

Matillion ETL API - v1 - Matillion Docs

Managing Python on a Matillion ETL virtual machine (VM)This guide was provided by Matillion's solution architect team.Python is a popular programming language for data engineers. Recognizing this, Matillion ETL offers a Python Script component, which allows Matillion users to integrate their own Python scripts into their Matillion ETL jobs. When using Python scripts in Matillion ETL jobs, an important consideration is if the nature of the Python is appropriate to run on a Matillion ETL instance, which is typically sized for an ELT workload. Read Executing Python Scripts Outside of Matillion for more insights into that topic.When Matillion ETL users reach out to Matillion Support related to their use of Python, we've found that, often, the issues raised relate to the management of Python on their Matillion ETL instances. The aim of this guide is to highlight some best practices around managing your Python environment on a Matillion ETL instance.Best PracticesDo not uninstall Python on a Matillion ETL instance. An alternative is to disable the availability of the Python Script component.Do not change the version of Python installed on a Matillion ETL instance.Maintain an inventory of any manually installed Python libraries, including the version of the Python library.When automating the deployment of new Matillion ETL VMs, account for any Python library dependencies as part of the automated deployment.When using the Python Script component, use the Python3 interpreter.Do not change the version of pip installed on a Matillion ETL VM unless there is a Python library dependency. If required to update the version of pip, ensure you have a current backup of the Matillion ETL VM.Python Interpreters and VersionsThe Python Script component in Matillion ETL allows a user to run a Python script against different Python interpreters: Jython, Python2, and Python3.The Jython interpreter is a Java interpreter, based on Python2, for running Python scripts within a Java application. Matillion ETL is written in Java, which is where the support for this interpreter comes from. Historically, the main benefit of using the Jython interpreter is that it allows the Python script execution to use the connection to the cloud data warehouse (CDW) That the Matillion ETL job creates at runtime. One would typically use this feature to assign values to Matillion variables during a job's execution.Python2 and Python3 run outside of Java and thus do not have this capability and would require the Python script to additionally create a connection to the CDW. Matillion ETL now has a Query Result To Scalar component, and a Query Result To Grid component, which provide a simpler way to populate variables within a Matillion ETL job, and remove the need for using Jython for this particular use case.Python2 was sunset on 1st January 2020 and is no longer being maintained. As of version 1.61.6, Matillion ETL comes with Python 2.7.5 installed.For the above reasons, we recommend using Python3 for any new Python Script development. Matillion ETL continues to support the Jython and Python2 interpreters, primarily to support users who have existing Jython or Python2 dependencies in their jobs. However, it is possible for support of the Jython or Python2 interpreters to be removed in a future release of Matillion ETL.For any users who do have dependencies on Jython or Python2 in their jobs, we recommend transitioning those over to Python3, so as to best future-proof your Matillion ETL jobs. As of version 1.61.6, Matillion ETL comes with Python 3.6.8 installed.We do not recommend changing the version of Python that is installed on your Matillion ETL instance. When needed, updates to the version of Python will be bundled along with new versions of Matillion ETL. Updating or changing the version of Python2 or Python3 on a Matillion ETL instance can result in issues or instability with the Matillion ETL application itself.In addition to the above recommendation, please also note that Python should not be uninstalled from the Matillion ETL instance. Prior to version 1.60, the Matillion ETL application has dependencies on Python, and removing Python from a Matillion ETL instance can result in uninstalling the Matillion ETL application as well. As an alternative to uninstalling Python from a Matillion ETL instance, consider disabling the Python Script component instead.PIP VersionsPython installations will by default have a set

Matillion Reviews: What Is It Like to Work At Matillion?

Azure DevOps is a highly flexible software development and deployment toolchain. It integrates closely with many other related Azure services, and its automation features are customizable to an almost limitless degree. Matillion ETL is a cloud-native data integration platform, which helps transform businesses by providing fast and scalable insights. Matillion ETL's DevOps artifacts are source code and configuration files, and they are accessible through a sophisticated REST API. Great flexibility in both platforms means it's possible to integrate Matillion ETL with Azure DevOps in many different ways. It can be difficult to decide how best to proceed! To help with that, we present five best practices that will help you get the most out of Azure DevOps in a Matillion ETL software development context. Things to know:The Matillion ETL application consists of a number of related jobs which between them perform data extraction, load and integration using a Cloud Data Warehouse (CDW).Configuration data that varies between CDW environments, such as role-based access control metadata in the form of grants and roles, is held in administrative scripts held under source control alongside the Matillion application.The CI/CD pipeline workflow is initiated when a developer saves updates into the source code repository. The goal of the automation is to deploy those changes to Production in a governed and efficient way.Each of the following five best practices includes practical, hands-on code samples and screenshots taken from the above scenario. We will be using GitHub Actions as the CI/CD workflow provider. You can download the full YAML configuration file from among the links at the end of the article. 1. Choose your methodologyEvery contemporary cloud-native application typically has many components and interdependencies. This particularly applies in the stateful world of data processing. Successful deployment of a cloud native data processing application typically requires the interoperation of multiple managed services. Automating the build and deployment needs a DevOps framework that is sophisticated enough to manage all the interdependencies. In the deployment scenario we are following here, we have to make all of the following technology components work together:Azure DevOps itselfGitHub-hosted Job RunnersThe Matillion HubARM templatesAzure Network Security GroupsAzure IAMThe Matillion ETL REST APICloud Data WarehouseIt's therefore vital to follow an application design methodology that gives the best opportunity for success, and use a DevOps methodology that’s capable of working in that context. A widely endorsed example is the Twelve-Factor application. Here is a screenshot of the

Script to a user of lesser privileges. Read How to place restrictions on Bash and Python components.Virtual EnvironmentsAdvanced Python users sometimes enquire about whether Matillion ETL supports Python Virtual Environments. As of version 1.61.6 of Matillion ETL, Python Virtual Environments are not currently supported. However, there exists a Matillion ETL Shared Job on the Matillion Exchange job list that can be used to emulate Python Virtual Environments. Here is a link to the Pip3 Install Shared Job that serves this purpose.Executing Python Scripts external to Matillion ETLAs discussed in the beginning of this article, when running Python scripts, one should consider the resources required to run that Python code. If the nature of the Python code is such that it exceeds the resources available on a Matillion ETL instance, there are different methods to approach this scenario.Executing Python Scripts Outside of Matillion describes numerous techniques on approaching this scenario.Another approach to this scenario is described in our blog article about serverless file conversion with Matillion ETL. The pattern described in this blog post leverages another Shared Job on the Matillion Exchange. The Run Serverless Shared Job offers the capability to dynamically create and execute your own Python code via an AWS Lambda function.. Matillion was founded in 2025.

Create a Key and a Secret Key by following “Create Access Key”.IAM in AzureWithin Azure, Roles and Identities are managed by a cloud hosted version of Active Directory, known as a “tenant” or a “directory.” There are many fine-grained privileges, grouped broadly as:Owner – The most powerful administrator privilegeContributor – Full access, but without user administration privilegesReader – Read-only accessService-specific privilegesTo use Instance Credentials, start by creating a Managed Identity. Grant the minimum set of privileges for the cloud services you intend to use with Matillion. To attach it to a virtual machine, first switch off the system-assigned identity in the Identity Settings panel:Then add the Managed Identity in the User Assigned settings.To use Instance Credentials with Matillion in Azure, create a Managed Identity with the minimum set of privileges, and assign the Managed Identity to your virtual machineTo use a Secret rather than Instance Credentials in Azure means creating an App Registration.
