## Proposed changes Opt zstd block decompression by `ZSTD_decompressDCtx()` to replace streaming decompression. It will improve performance but consume more memory. Test result: - env: 1 node(16 cores, 64G). - parquet column: 100 million rows of char(255) column. - result: 5.2 -> 4.6. ## Further comments If this is a relatively large or complex change, kick off the discussion at [d...@doris.apache.org](mailto:d...@doris.apache.org) by explaining why you chose the solution you did and what alternatives you considered, etc... -- This is an automated message from the Apache Git Service.
