Data Factory adds new hierarchical data handling and new flexibility for complex joins
Published date: 01 May, 2020
Our most recent updates to Data Factory include:
- Hierarchical data modeling in data flows has been expanded with Flatten, collect aggregation and updated sink mapping. We've also published a new tutorial on how to use these capabilities when moving from relational to hierarchical with Azure SQL DB and CosmosDB.
- Non-equi join support added to Join, Lookup, and Exists transformations will land in the coming weeks. You will now be able to add non-equi joins to all ADF join types in the UI and add "and" conditions with additional equi/non-equi types.
- An update that already landed in ADF for Joins, Exists and Lookups is an update to the Optimise tab. You can now switch off native Spark data push-down to execution nodes when performing a join using the broadcast option. The default is auto and you can use "fixed" override the default data flow behavior in Spark by broadcasting only left or right side.
