New Features in Release 22.1
JSON MRCounter Types
The MR_COUNTER SQL type can now be used in JSON fields for multi-region tables. The change adds support for merging independent modifications made in multiple regions into a single combined value to schemaless JSON fields.
Elasticity for MR Tables
Stores that contain multi-region tables now support elasticity changes that change the store topology.
Child tables for MR Tables
Multi-region tables now support child tables. Child tables always inherit the regions of the associated top level tables.
KVLocal
Applications can now create and manage a small, standalone store instance using the new KVLocal class.
Deprecating Import/Export Utility
Release 22.1 is the final release to include the import/export utility. It will be removed as of the next quarterly release. We have moved the functionality of the import/export utility over to the data migrator. Chapter 7 of the Oracle NoSQL Database Administrator's Guide contains details on using the data migrator as well as a comparison between the import/export utility and the data migrator. The import/export utility has been deprecated since the 20.3 release and we encourage customers to move to the new data migrator utility now.
