 Row mode memory grant feedback expands on the batch mode memory grant feedback feature by adjusting memory grant sizes for both batch and row mode operators.  
 
 To enable the public preview of row mode memory grant feedback in Azure SQL Database, enable database compatibility level 150 for the database you are connected to when executing the query.

 ## Batch mode Adaptive Joins
 The batch mode Adaptive Joins feature enables the choice of a [Hash Join or Nested Loops Join](../../relational-databases/performance/joins.md) method to be deferred until **after** the first input has been scanned. The Adaptive Join operator defines a threshold that is used to decide when to switch to a Nested Loops plan. Your plan can therefore dynamically switch to a better join strategy during execution.
