Not a bug, this is expected behavior of the AO library, see comment below.
Custom created database index in AO_60DB71_LEXORANK table gets dropped during Jira startup
- Create a custom database index in Lexorank table, e.g.:
- Restart Jira
The index is retained in the database after the restart.
The index gets removed during the startup.
Enabled SQL logging shows "DROP INDEX" command executed during startup in atlassian-jira.log:
Currently there is no known workaround for this behavior. A workaround will be added here when available
