Improvements, new features and functionality

Core Replicator

  • The replicator now includes real-time performance monitoring to track and identify slow database operations during replication. The feature provides visibility into transaction, event, and statement execution times with configurable thresholds for alerting. For more information on configuring and using this feature, see trepctl perflog Command

    Issues: CT-2629

Bug Fixes

Installation and Deployment

  • Fixed an installation issue when using MariaDB 10.6 with SSL. Previously, this would have failed to install showing an error message like :

    Issues: CT-2624

Command-line Tools

  • Fixed a bug that would cause tprovision to fail if the password contained double-quotes.

Backup and Restore

  • Fixes an issue when, in certain cases, a newly provisioned database would be left in the offline_mode.

    Issues: CT-2660
