    Engine : Hive vs Spark

    Active Member



      We have a mapping with Hive as an source/target. When choosing the execution engine, which can be preferred?

          We recommend choosing all available engines and let the service decide which is the best. Spark is the preferred engine in the newer versions and will revert to Blaze if the mapping cannot be executed in Spark due to functionality limitation like profiling etc. If you have to configure an engine manually, Spark should suffice and you may configure Blaze as a backup if needed.


          Please refer the blog post which talks about deprecation of Hive engine in upcoming versions -
