Hi all,

As Microsoft announced gen 1 retirement , can anyone give insight regarding support for azure data lake analytics to gen 1 after feb 2024?
For gen 2 , ADLA still not supporting abfs driver fl, is there any plan for giving gen 2 storage support to ADLA service?
One of our enterprise customer is using this service and we would like to know path going forward and how much we can depend on this native azure service for enterprise solutions .


Thanks

Thanks for your query, ADLA (Azure Data Lake Analytics) is not supported on ADLS Gen2 today, given we are not investing in ADLA, we do recommend customers migrate ADLA to an alternate framework such as Azure HDInsight, Azure Synapse Analytics or Azure Databricks. If you are interested in learning more, kindly email us at ADLSGen1toGen2MigrationQA@service.microsoft.com.

Could you please confirm that I understand correctly then: after the retirement on Feb. 29, ADLA will be completely non-functional, since it requires gen1 to operate?

    Azure Data Lake Storage Gen1 is a service that was purpose built to serve as the
    storage platform for analytics workloads. In Feb 2019, we announced the general
    availability of Azure Data Lake Storage Gen2 (ADLS Gen2), a capability on Azure
    Blob Storage to support analytics workloads. ADLS Gen2 not only matches all the
    capabilities provided by ADLS Gen1 for analytics workloads but is also builds on the
    Azure Blob Storage features to make it the most comprehensive Data Lake Storage
    available in the Public Cloud or on-premises.

  • What are the benefits of migrating to ADLS Gen2 ?
    ADLS Gen2 not only matches all the capabilities provided by ADLS Gen1 for
    analytics workloads, but it also builds on the Azure Blob Storage features to make it
    the most comprehensive Data Lake Storage available in the Public Cloud or on-
    premises.

    Lower cost of storage compared to ADLS Gen1
    Tiered storage to manage costs
    High availability and disaster recovery capabilities
    Global availability in all Azure regions
    Automated storage lifecycle management policies


    ADLS Gen2 is also integrated with all the newer Azure Analytics offerings such as
    Azure Synapse Analytics, along with Azure Databricks, Azure HDInsight and Azure
    Purview and offers a rich eco system of partner solutions.

  • Will my application perform as well on Azure Data Lake Storage Gen2 as it does on
    Azure Data Lake Storage Gen1?
    Our goal is that the application performance for Azure Data Lake Storage Gen2 will
    be as good or better than Azure Data Lake Storage Gen1.

    Customers will not be able to do the following.

    Access the data through the Azure portal or the ADLS Gen1 APIs/SDKs/client tools
    Receive service updates to ADLS Gen1 or APIs/SDKs/Client tools
    Receive support for issues on ADLS Gen1 (phone, email, web).
