I got a bwc test failure on the yaml tests in Serverless - I guess because in bwc scenarios, the default setting is initially to allow partial results, but the test specifically expects to fail. The original PR made the test stricter to force strict handling of partial failures here; to make the test pass, I specifically won't revert this part, which is fine as it only makes the test more specific. |
Reverting it results in bwc test failures on Serverless.

Fix #126275
@idegtiarenko and I investigated and believe this needs reverting: silently dropping results from the query response in case any index is missing can lead to real problems if users don't spot their mistake. I'm also not sure if all the results will get dropped, or only from some nodes/shards/clusters, meaning that this might be hard to spot by users if only some results get dropped.
The main PR has no transport version bump, no new ESQL capability, and was merged 15h ago - so it should be safe to just revert it. I noticed there was a linked Serverless PR on the original PR, but it merely disabled some obsolete tests on Serverless and doesn't require reverting itself.
