We currently have a 155 GB index. Our plan is to disable data recording in it, then run a force merge, and afterwards perform a soft delete cleanup. Could you please clarify: after running the force merge and soft deletes, will it still be possible to re-enable the index and continue writing new data to it?
Hi!
That should work. However, force-merge might not be the best approach if you plan to keep writing to the index.
Reason: it can leave you with huge segments that won’t be merged for a long time and can hurt search and increase disk use.
As always, I’d recommend testing stuff and in this very case: rollover + ILM.
