Description
Is your feature request related to a problem? Please describe.
The issue entails the tasks that are essential to ensure robustness for ZSTD.
Describe the solution you'd like
- Long running tests to verify for any corruption or memory leaks
- Reindexing between different compression codecs
- Create a snapshot, delete an index, restore from snapshot
- Split/Shrink api since they modify segments to some extent
- Index Blocks
- Upgrade from the earliest version supported for version upgrade to 2.x (from os 1.0/es 7.9)
- Upgrade from the n-1 version
- Minor version upgrade with zstd and zstd no dict segments
- Force merge of segments with multiple compression mode into zstd
- Close an index, update the setting, test the indexing and search flows, snapshots, etc i.e. with multiple compression settings on different segments
- Move ZStd compression codecs to plugins from core (Optional)
