03/27/2023, 6:57 AMWith reindexing you can perform schema changes, repartition data, filter out unwanted data, enrich existing data, and so on.
With compaction you can optimize segment size for better query performance.

03/27/2023, 8:53 AMCompaction is simpler than re-indexing in two situations, one of which is to schedule it via auto-compaction.
The other is that it also doesn't require you to know or configure the schema and granularities of the datasource as they are auto-determined
