A.1. Tungsten Replicator 8.0.1 GA (Not Yet Released)

Version End of Life. Not Yet Set

Release 8.0.1 ...

Behavior Changes

The following changes have been made to Tungsten Replicator and may affect existing scripts and integration tools. Any scripts or environment which make use of these tools should check and update for the new configuration:

  • Installation and Deployment

    • tpm validate now verifies localhost is defined in /etc/hosts

      Issues: CT-2564

  • Command-line Tools

    • The tprovision command no longer requires the external tool tungsten_get_mysql_datadir.

      Additionally, the tool has been significantly re-factored for greater stability, performance and functionality.

      Issues: CT-2597

Improvements, new features and functionality

  • Command-line Tools

    • New Feature: tpm ini upgrade --ini {fullpath} will display all changes to the specified INI file that would be performed by the tpm update commands during a version upgrade. Adding the --write argument would apply the changes to the specified file as well.

      Issues: CT-2601

  • Monitoring

    • Additional prometheus metrics have been added to the Replicator:

      • tungsten_replicator_service_online_duration_seconds gauge show duration in seconds since the replicator was put online.

      • tungsten_replicator_task_total counter shows statistics by service, stage and task as shown in the following example:

        tungsten_replicator_task_total{service="alpha",stage="q-to-dbms",task_id="1",stat="extract_time",} 250.015

        In this case, this is the extract time spent by the task #1 of the q-to-dbms stage of the alpha service. This is similar to the new trepctl perf output.
