Lars Hofhansl commented on HBASE-14613: --------------------------------------- Didn't think my musing about G1 and MSLAB would lead to a long a useful discussion :) Should we set InitiatingHeapOccupancyPercent based on configuration? By default we allow 40% of the heap for block cache and 40% for the memstore. When configured such, should we set InitiatingHeapOccupancyPercent to 80? Or maybe if we assume the memstores are on average 1/2 filled maybe this reasoning would lead to 60% as a good default...? > Remove MemStoreChunkPool? > ------------------------- > > Key: HBASE-14613 > URL: https://issues.apache.org/jira/browse/HBASE-14613 > Project: HBase > Issue Type: Brainstorming > Reporter: Lars Hofhansl > Priority: Minor > Attachments: 14613-0.98.txt, gc.png, writes.png > > > I just stumbled across MemStoreChunkPool. The idea behind is to reuse chunks > of allocations rather than letting the GC handle this. > Now, it's off by default, and it seems to me to be of dubious value. I'd > recommend just removing it. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
