Search index shards and snapshot metadata
Serves read-only index shards to query nodes. Writes go through the indexing pipeline, never here.
| Shard set | Documents | Rebuilt |
|---|---|---|
| catalog-v4 | 2.1 M | nightly |
| docs-v2 | 480 K | hourly |
| archive-v1 | 9.6 M | weekly |
Snapshot integrity is verified after each rebuild; failed shards are withdrawn from rotation.
