Hello Is there any way of changing the merge settings of a live index without downtime in ES versions prior to 1.4 (I'm on 1.1.1)?
After toying with some of the settings for quite a while (such as index.merge.policy.expunge_deletes_allowed and index.merge.policy.max_merge_at_once_explicit) I had come to the conclusion that they were NOT updating dynamically. A dive into the code, which also led to this issue <https://github.com/elasticsearch/elasticsearch/issues/7699>, seems to indicate that prior to 1.4 merge settings are not really dynamically updateable, and instead would require restarting, closing/reopening an index, or perhaps relocating shards (the updated values are stored, but never seem to be applied). I'm looking in TieredMergePolicyProvider to get this information. I'm planning on trying to update our cluster to 1.4 once it's stable, but until then it would be helpful to be able to tweak these settings as part of my battle against deleted document creep. So, am I missing something here, or is simply not possible right now? -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
