Heap fragmentation in region server
-----------------------------------
Key: HBASE-3455
URL: https://issues.apache.org/jira/browse/HBASE-3455
Project: HBase
Issue Type: Brainstorming
Components: performance, regionserver
Reporter: Todd Lipcon
Attachments: HBasefragmentation.pdf
Stop-the-world GC pauses have long been a problem in HBase. "Concurrent mode
failures" can usually be tuned around by setting the initiating occupancy
fraction low, but eventually the heap becomes fragmented and a promotion
failure occurs.
This JIRA is to do research/experiments about the heap fragmentation issue and
possible solutions.
