Andrew Purtell resolved HBASE-2055. ----------------------------------- Resolution: Invalid Not going to happen > Serialize WAL as Avro records > ----------------------------- > > Key: HBASE-2055 > URL: https://issues.apache.org/jira/browse/HBASE-2055 > Project: HBase > Issue Type: Improvement > Reporter: Andrew Purtell > Priority: Minor > Attachments: HBASE-2055-v2.patch, HBASE-2055-v3.patch, > HBASE-2055-v4.patch, HBASE-2055.patch, > TEST-org.apache.hadoop.hbase.TestFullLogReconstruction.txt.gz, > TEST-org.apache.hadoop.hbase.regionserver.wal.TestHLog.txt.gz, > TEST-org.apache.hadoop.hbase.regionserver.wal.TestLogRolling.txt.gz, > jackson-core-asl-1.0.1.jar, jackson-mapper-asl-1.0.1.jar, paranamer-1.5.jar, > test-site.patch > > > 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 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. -- This message was sent by Atlassian JIRA (v6.2#6252)
