Improvements, new features and functionality (2)

Command-line Tools (1)

• tpm diag outputting table information via route -n , and has two new command-line arguments: --include and --groups.

  --include specifies a comma-separated list of subroutines to include. Any gather subroutine not listed will be skipped.

  --groups specifies a comma-separated list of subroutine groups to include. Any group not listed will be skipped.

  Issue: CT-1399

Filters (1)

• A number of sql_modes have been removed in MySQL 8.0, meaning that when replicating from an earlier version (e.g. 5.7) the applier could error when applying session variables.

  A new dropsqlmode filter is now available that should be configured against appliers where the source is version 5.7 or earlier and the target is version 8.0 or later.
