In addition to the performance improvements, we’ve also added new functionality to Databricks Delta:
Truncate Table: with Delta you can delete all rows in a table using truncate. It’s important to note we do not support deleting specific partitions. Refer to the documentation for more information: Truncate Table
Alter Table Replace columns: Replace columns in a Databricks Delta table, including changing the comment of a column, and we support reordering of multiple columns. Refer to the documentation for more information: Alter Table
FSCK Repair Table: This command allows you to Remove the file entries from the transaction log of a Databricks Delta table that can no longer be found in the underlying file system. This can happen when these files have been manually deleted. Refer to the documentation for more information: Repair Table
Scaling “Merge” Operations: This release comes with experimental support for larger source tables with “Merge” operations. Please contact support if you would like to try out this feature.
Looks like a nice set of reasons to upgrade.
