backup: compaction dist sql processor now handles errors correctly

kev-cao · kev-cao · commit aa9c18f270a5 · 2025-04-17T18:45:58.000Z
Previously, when one of the processor nodes in the backup compaction
dist SQL plan ran into an error, the compaction job would continue on,
blissfully unaware of the error. This would result in faulty job
successes. This patch fixes the coordinator node so that errors from
other nodes is properly handled and surfaced.

Epic: None
