Akash Ashok reassigned HBASE-4529: ---------------------------------- Assignee: Akash Ashok > Make WAL Pluggable > ------------------- > > Key: HBASE-4529 > URL: https://issues.apache.org/jira/browse/HBASE-4529 > Project: HBase > Issue Type: Improvement > Components: regionserver, wal > Reporter: Akash Ashok > Assignee: Akash Ashok > Labels: regionserver, wal > > Make WAL a pluggable, configurable component, thus making it easier to write > to different filesystems (including multiple filesystems). > From Stack: > Pluggable WAL component would need to check that the split can deal w/ > multiple logs written by the one server concurrently (sort by sequence > edit id after sorting on all the rest that makes up a wal log key). > From Jesse Yates: > It would be nice to be able to tie pluggable WAL component into a service > that logs directly to > disk, rather than go through HDFS giving some potentially awesome speedup at > the cost of having to write a logging service that handles replication, etc. > From Karthik Tunga: > Along with the log replaying part, logic is also needed for log roll. > This, I think, is easier compared to the merging of the logs. Any edits less > than the last sequence number on the file system can be removed from all > the WALs. -- This message is automatically generated by JIRA.
