branch-4.1: [feature](be) Support zstd stream load compression #64711#64750
Merged
Conversation
Stream load does not support `compress_type=zstd` in the shared load format parser. Async group commit also checks only legacy compressed CSV format enum values when estimating compressed input size, so `compress_type` based compressed input is not handled consistently by stream load and HTTP stream load. This PR adds ZSTD parsing in `LoadUtil::parse_format`, adds a shared `LoadUtil::is_compressed_load` helper for `compress_type` and legacy compressed CSV format types, and uses it in stream load and HTTP stream group commit paths. This PR also adds BE UT and regression coverage for ZSTD CSV/JSON stream load and group commit stream/HTTP stream load.
