stack created HBASE-19645: ----------------------------- Summary: Add global barrier for offheap usage Key: HBASE-19645 URL: https://issues.apache.org/jira/browse/HBASE-19645 Project: HBase Issue Type: Task Reporter: stack
See discussion at the end of HBASE-16747. In synopsis, we do not have a global limit for offheap usage; we do no global accounting. There are the offheap buffers, short-circuit read buffers, offheap memstores, etc. Ideally, as for onheap, when we approach threshold, we'd bring on flushing to clear out offheap usage or make use of onheap.
