[GitHub] [pinot] mneedham opened a new pull request, #8505: Error message if the dimension table in memory hasn't been populated
mneedham opened a new pull request, #8505:
URL: https://github.com/apache/pinot/pull/8505
There's a scenario where the Pinot Server previously downloaded the segment for a dimension table and is then restarted, which means the `addSegment` flow doesn't get called.
This means that the in-memory `DimensionTable` is empty and the `lookupJoin` function always returns null values. I'm not sure what the proper solution for solving that problem is - I guess the user could delete the segment and re-download it?
But this PR doesn't address that - instead, it throws an exception if you try to do a lookup join when the in-memory dimensions table is empty.
