WiredTigerHS.wt is growing enormously

Hi Team, We have upgraded our mongodb standalone community version from 4.4 → 5.0 → 6.0 → 7.0 2 days back, after that, WiredTigerHS.wt file in mongodb data directory growing huge, we restarted the db multiple times, but the size is not reducing and continuously grows. We suspected a TTL index is causing this which was created after the upgrade, we have dropped the index, but still that didn’t fix the issue.

Hello Raghunath,

Were you able to find a solution for this issue?
Also, this issue is reported in many threads, but nothing seems to be providing any solution at all!!

The growth of the history store file depends on the database write activity. Have you tried reducing minSnapshotHistoryWindowInSeconds?
