[jira] [Created] (FLINK-24564) Change the default compression to snappy for parquet, orc, avro in table

Jingsong Lee created FLINK-24564:
------------------------------------

             Summary: Change the default compression to snappy for parquet, orc, avro in table
                 Key: FLINK-24564
                 URL: https://issues.apache.org/jira/browse/FLINK-24564
             Project: Flink
          Issue Type: Improvement
          Components: Formats (JSON, Avro, Parquet, ORC, SequenceFile), Table SQL / Runtime
            Reporter: Jingsong Lee
             Fix For: 1.15.0


According to the experience of other frameworks, snappy compression is recommended by default, which will reduce the file size.
This does not affect reading, because these formats will automatically uncompress the file according to the head information of the file.
