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? {quote} 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. {quote} (I wonder if the meta log should become a system tables log now?) {quote} 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? > Implement namespace > ------------------- > > Key: HBASE-8408 > URL: https://issues.apache.org/jira/browse/HBASE-8408 > Project: HBase > Issue Type: Sub-task > Reporter: Francis Liu > Assignee: Francis Liu > Attachments: HBASE-8015_11.patch, HBASE-8015_12.patch, HBASE-8015_1.patch, HBASE-8015_2.patch, HBASE-8015_3.patch, HBASE-8015_4.patch, HBASE-8015_5.patch, HBASE-8015_6.patch, HBASE-8015_7.patch, HBASE-8015_8.patch, HBASE-8015_9.patch, HBASE-8015.patch, TestNamespaceMigration.tgz, TestNamespaceUpgrade.tgz > > -- This message is automatically generated by JIRA.
