tibdg purge

When tables and indexes are deleted, they are not automatically removed from the grid configuration. Over time, the data stored for those tables and indexes are deleted by the nodes but their existence is still recorded in the grid configuration. In environments where tables and indexes are frequently created and destroyed, the grid configuration can grow quite large. This results in operations that change the grid configuration taking progressively longer and longer. The tibdg purge commands are designed to address this issue.

A table or index can only be purged once all the nodes in all the copysets have deleted the data for that node or index.

All the nodes in all the copysets must be running for these purge commands to work.

tibdg table purge

The tibdg table purge command removes all the deleted tables and their indexes that had their data deleted from every node in every copyset.

tibdg index purge

The tibdg index purge command removes all the deleted indexes that had their data deleted from every node in every copyset. This command does not purge indexes from deleted tables. To purge those indexes, use the tibdg table purge command.
