Subject [jira] Created: (HBASE-2055) Serialize WAL as Avro records
Date Fri, 18 Dec 2009 18:22:18 GMT
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-dev@.
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
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.
