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. > https://github.com/apache/arrow/pull/807/files might be a useful crib sheet > for how to add a compressor. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-all-unsubscr...@impala.apache.org For additional commands, e-mail: issues-all-h...@impala.apache.org
