I would like to place a feature request to add Shrink Index or reduce Number of Shards in the Index Management actions

Just like the Force merge, Read, Replica Count etc. it would be great to have Shrink index, to reduce the number of shards in the actions section. This will be a good feature to have for Managed indices

Currently its really hard to manage the indices as they are managed with setting the number of shards at the creation of index and only increasing the number of replicas. I am currently using managed index only for small indices. For larger indices, the indices are managed outside of Index Management by creating new weekly index with less number of shards and reindex all the daily indices in the week into the weekly index

Thanks

Hi @yc1024, it's definitely on our backlog of things to add, but as of right now it hasn't been scheduled yet. Will update this issue when the status changes.

This would be useful. It is nice to reduce the shard count after moving an index to "warm" / "cold", for workloads that require a large shard count for writes but not for reads / long term storage.

+1 , same issue with needing many shards for ingest and then shrink down for reading.
