* refactor: simplify `QueryChunk` data access We have only two types for chunks (now that the RUB is gone): 1. In-memory RecordBatches 2. Parquet files Loads of logic is duplicated in the different `read_filter` implementations. Also `read_filter` hides a solid amount of logic from DataFusion, which will prevent certain (future) optimizations. To enable #5897 and to simplify the interface, let the chunks return the data (batches or metadata for parquet files) directly and let `iox_query` perform the actual heavy-lifting. * docs: improve Co-authored-by: Andrew Lamb <alamb@influxdata.com> * docs: improve Co-authored-by: Andrew Lamb <alamb@influxdata.com> Co-authored-by: Andrew Lamb <alamb@influxdata.com> Co-authored-by: kodiakhq[bot] <49736102+kodiakhq[bot]@users.noreply.github.com> |
