We recently enabled the feature to return exceptions for cases when some segments are missing (as opposed to returning partial results).

This feature was rolled out in #7823.

After enabling it we have started seeing the following error occasionally for our Realtime tables. On digging a bit we found that this error comes when a segment is deleted due to retention.

ServerSegmentMissing:1 segments [<segment-name>] missing on server: <server-name>, errorCode:235
