How to roll back tsi1 index to inmem in production


We are seeing exorbitant disk space usage after migrating to tsi1 indexes with almost no visible performance gains .

We need guidance how to rollback to inmem indexing.

Is there a quick rolback method

current influxdb version 1.6.0

Any help appreciated.

Thanks in advance/


I see that we can just do

  1. Enable inmem .
  2. Delete all shard index directories.
  3. Restart the influxdb service.

how to delete the index dir ?
I see under the “autogen”

is the idx file that needs to be removed ?

or is it the “_series” dir that needs to be removed.

Any help appreciated.


Got it … I did find the index dir in each shard !
