[jira] [Created] (HBASE-4887) Write full enum name of
Compression.Algorithm into HFile
Write full enum name of Compression.Algorithm into HFile
--------------------------------------------------------
Key: HBASE-4887
URL: https://issues.apache.org/jira/browse/HBASE-4887
Project: HBase
Issue Type: Improvement
Reporter: Ted Yu
Currently the ordinal of compression algorithms is used.
This places unnecessary constraint when new compress algorithm is added.
We should write full enum name of Compression.Algorithm into HFile

[jira] [Commented] (HBASE-4887) Write full enum name of

Jimmy Xiang commented on HBASE-4887:
------------------------------------
Using full enum name is great. Since the ordinal in the file is an integer, to use enum name which is a string, we may need to increase the file version, or using some trick (for example, writing -1, then the enum name).
How about a different solution? Introducing an Id to the enum, for those existing Compression.Algorithm, we use their current ordinal as their Ids. For new compress algorithms, their ordinal will not matter any more.
