OpenSearch keyword-sort investigation

Benchmarked five OpenSearch releases and linked slower keyword sorting to a Lucene optimization threshold. In synthetic tests, lowering max_clause_count from 1024 to 128 made sorts roughly 2–3× faster on 2.12.0, 2.19.0, and 3.8.0, with little change on older controls. Upstream investigation remains open.

Preserving shard routing during OpenSearch migrations

Investigated a migration failure where a missing number_of_routing_shards setting concentrated writes on fewer shards, and reported it with a reproducible case. Maintainers resolved the report in March 2026 with a fix that preserves that setting and adds regression tests.
