> Implement dedicated WAL for system tables
> -----------------------------------------
>
> Key: HBASE-14623
> URL: https://issues.apache.org/jira/browse/HBASE-14623
> Project: HBase
> Issue Type: Sub-task
> Components: wal
> Reporter: Ted Yu
> Assignee: Ted Yu
> Labels: wal
> Fix For: 2.0.0

> Attachments: 14623-v1.txt, 14623-v2.txt, 14623-v2.txt, 14623-v2.txt,

> As Stephen suggested in parent JIRA, dedicating separate WAL for system
> tables (other than hbase:meta) should be done in new JIRA.
> This task is to fulfill the system WAL separation.
> Below is summary of discussion:
> For system table to have its own WAL, we would recover system table faster
> (fast log split, fast log replay). It would probably benefit
> AssignmentManager on system table region assignment. At this time, the new
> AssignmentManager is not planned to change WAL. So the existence of this JIRA
> is good for overall system, not specific to AssignmentManager.
> There are 3 strategies for implementing system table WAL:
> 1. one WAL for all non-meta system tables
> 2. one WAL for each non-meta system table
> 3. one WAL for each region of non-meta system table
> Currently most system tables are one region table (only ACL table may become
> big). Choices 2 and 3 basically are the same.
> From implementation point of view, choices 2 and 3 are cleaner than choice 1
> (as we have already had 1 WAL for META table and we can reuse the logic).
> With choice 2 or 3, assignment manager performance should not be impacted and
> it would be easier for assignment manager to assign system table region (eg.
> without waiting for user table log split to complete for assigning system
> table region).
