mapleFU commented on issue #43716: URL: https://github.com/apache/arrow/issues/43716#issuecomment-2314456266
I've read the related code in Velox[1] and arrow-rs[2], they use similiar encoding here. List: ``` [null-flag][element-count] [ element +] ``` Element list is stored together or in variable-length area. Struct: ``` [null-flag][elements] ``` I'd like to: 1. Finish https://github.com/apache/arrow/issues/43758 firstly 2. Support (non-nested) List in RowEncoder 3. Support in HashJoin / SwissJoin In the future more types ( included nested ) can be supports cc @pitrou @zanmato1984 [1] https://github.com/facebookincubator/velox/blob/db8875c425e8132f553adf12e106cd2e28a811c0/velox/exec/ContainerRowSerde.cpp [2] https://github.com/apache/arrow-rs/blob/master/arrow-row/src/lib.rs#L147 -- This is an automated message from the Apache Git Service.
