Thanks for the detailed source-code references! You are correct on both counts: 1. The default really is **LZ4F** before 4.0.3 (not `lz4`). The change to `ZSTD` landed in apache/doris#58923 (`dev/4.0.3-merged`). 2. The valid-values list was also incomplete — the actual accepted values are `LZ4, LZ4F, LZ4HC, ZLIB, ZSTD, SNAPPY, NONE` (case-insensitive), per `PropertyAnalyzer.stringToCompressionType`. Fix opened in #3746 covering current/dev and 4.x, EN + zh. Note: the FE config `default_compression_type` doesn't exist in `branch-2.1` or `branch-3.0` of apache/doris, so the 2.1 docs don't need this entry. The LZ4F values you cited from `tablet_schema.h` / `segment_v2.proto` / `olap_file.proto` are the BE-side storage defaults, which are a separate layer from this FE config (the FE config controls the default for newly created tables; the proto defaults govern serialized fallback at the BE storage layer). For 3.1.3, the FE config default of `LZ4F` matches the proto defaults you found, which is consistent. -- This is an automated message from the Apache Git Service.
