 ## Format Details
 
-| Format | Databricks name | Behavior |
-|--------|----------------|----------|
-| CSV | `CSV` | Writes header once, skips duplicate headers from subsequent chunks |
-| JSON_ARRAY | `JSON_ARRAY` | Wraps in `[]`, strips brackets from chunks, inserts commas |
-| ARROW_STREAM | `ARROW_STREAM` | Re-encodes RecordBatches into single IPC stream (not byte-concat) |
