[jira] [Created] (IMPALA-8450) Add support for zstd and lz4 in parquet

Tim Armstrong created IMPALA-8450:
-------------------------------------

             Summary: Add support for zstd and lz4 in parquet
                 Key: IMPALA-8450
                 URL: https://issues.apache.org/jira/browse/IMPALA-8450
             Project: IMPALA
          Issue Type: Improvement
          Components: Backend
            Reporter: Tim Armstrong


PARQUET-970 added these codecs to the format. We have LZ4 in the toolchain already and I just added zstd: https://gerrit.cloudera.org/#/c/13079/

These codec probably offer a better trade-off of density and speed than snappy or gzip.
