Virag Kothari commented on HBASE-12233:
---------------------------------------
bq. Right now meta gets 20000x more reads than writes on real production
clusters
Write throughput on meta become important during cluster startups, operations
like create/enable/disable and during rack failures. Any assignments involved
during such activity usually does minimum 2 writes to meta for a single region
as each region goes through at least 2 states.
So even in best case scenarios, there will be 2M writes just for bringing a
table with 1M regions online.
Although, a split meta would help with both reads and writes as discussed over
in parent JIRA.
