Serialize WAL as Avro records
-----------------------------
Key: HBASE-2055
URL: https://issues.apache.org/jira/browse/HBASE-2055
Project: Hadoop HBase
Issue Type: Improvement
Reporter: Andrew Purtell
Assignee: Andrew Purtell
Priority: Minor
There was some advocacy of using Avro for serialization of HBase WAL records up
on hbase-...@. Idea is Hadoop core is getting away from Writables and Avro is
the blessed replacement.
I think we have this criteria for its use:
1) Performance of writing Avro records is no worse than that for writing
Writables into a SequenceFile.
2) Space consumed by Avro serialization is no worse than that of Writables
3) File format is amenable to appends (cannot require valid trailers, etc.)
I'll put up a patch so we can try it out.
