I found a warning in this documentation page about updating index settings while they are closed:
Changing static or dynamic index settings on a closed index could result in incorrect settings that are impossible to rectify without deleting and recreating the index.
Source: Index modules | Elasticsearch Guide [7.17] | Elastic
Does this refer to any setting? If so, why is updating the settings allowed on a closed index?
What I want to achieve is to update the
index.codec setting, which can't be done while the index is open or I would get:
Can't update non dynamic settings [[index.codec]] for open indices ...
So I was considering closing the index before doing the update, but then it seems there is no guarantee my index can be reopened later?
ES version: 7.17, but the warning is also in the 8.x docs.
