Duo Zhang commented on HBASE-14969: ----------------------------------- [~apurtell] In this patch we move and remove some classes marked as {{IA.CONFIG}} and map the old class name to new class name in Factory class(which means we are still compatible with old config file). Does this break our compatibility assumptions? Thanks. > Add throughput controller for flush > ----------------------------------- > > Key: HBASE-14969 > URL: https://issues.apache.org/jira/browse/HBASE-14969 > Project: HBase > Issue Type: Improvement > Affects Versions: 2.0.0 > Reporter: Yu Li > Assignee: Yu Li > Fix For: 2.0.0, 1.3.0 > > Attachments: HBASE-14969.branch-1.patch, HBASE-14969.patch, > HBASE-14969_v10.patch, HBASE-14969_v2.patch, HBASE-14969_v3.patch, > HBASE-14969_v4.patch, HBASE-14969_v5.patch, HBASE-14969_v6.patch, > HBASE-14969_v9.patch, fd78628_9909808_compat_report.html, > load-nothrottling.log, load-throttling.log > > > In HBASE-8329 we added a throughput controller for compaction, to avoid spike > caused by huge IO pressure like network/disk overflow. However, even with > this control on, we are still observing disk utils near 100%, and by analysis > we think this is caused by flush, especially when we increase the setting of > {{hbase.hstore.flusher.count}} > In this JIRA, we propose to add throughput control feature for flush, as a > supplement of HBASE-8329 to better control IO pressure. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
