@advancedxy Yea, `CometRowToColumnarExec` could be a more general solution, not only for `InMemoryRelation`, but also for other types of data sources like CSV, JSON, etc. The advantage of implementing Arrow for `CachedBatchSerializer` here is that we can avoid the extra cost from row to columnar conversion, and potentially be more space efficient because of better compression. -- This is an automated message from the Apache Git Service.
