[jira] [Updated] (PARQUET-2217) Support gorilla encoding for float numbers

     [ https://issues.apache.org/jira/browse/PARQUET-2217?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Frank Dai updated PARQUET-2217:
-------------------------------
    Description: 
[Gorilla|https://www.vldb.org/pvldb/vol8/p1816-teller.pdf] is a de facto encoding algorithm for float numbers, it has been used by many time series database such as InfluxDB, TimescaleDB for a while.

For now Parquet only supports BYTE_STREAM_SPLIT encoding for float numbers, it would be nice to add gorilla encoding.
