Date Fri, 02 Aug 2013 23:39:48 GMT

    [ https://issues.apache.org/jira/browse/HBASE-8408?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13728267#comment-13728267

Francis Liu commented on HBASE-8408:

Francis Liu So, regards system tables, they are all treated like meta table? They all get
assigned out before user tables? Or does meta go out first before everything else and other
system tables are a new tier of assigning?
Currently system tables is a new tier. Meta first, then system, then users. Tho it's missing
the open handler queue and wal. Let's add it as a follow on patch.

(I wonder if the meta log should become a system tables log now?)
That would be the next state. We need to add the notion of priorities into system table which
we need anyway. As long as we keep the table sizes of system tables minimal. Else we risk
slowing down MTTR. Though that should be a general principle for system tables in any case?
