Xinli Shang updated PARQUET-1872: --------------------------------- Summary: Add TransCompression Feature (was: Add TransCompression command ) > Add TransCompression Feature > ----------------------------- > > Key: PARQUET-1872 > URL: https://issues.apache.org/jira/browse/PARQUET-1872 > Project: Parquet > Issue Type: Improvement > Components: parquet-mr > Affects Versions: 1.12.0 > Reporter: Xinli Shang > Assignee: Xinli Shang > Priority: Major > > When ZSTD becomes more popular, there is a need to translate existing data to > ZSTD compressed which can achieve a higher compression ratio. It would be > useful if we can have a tool to convert a Parquet file directly by just > decompressing/compressing each page without decoding/encoding or assembling > the record because it is much faster. The initial result shows it is ~5 times > faster. -- This message was sent by Atlassian Jira (v8.20.1#820001)
