Karthik Ranganathan updated HBASE-7163: --------------------------------------- Summary: Low-hanging perf improvements in HBase client (was: Change cachedRegionsLocations in HConnectionManager from SoftValueSortedMap to ConcurrentSkipListMap) > Low-hanging perf improvements in HBase client > ---------------------------------------------- > > Key: HBASE-7163 > URL: https://issues.apache.org/jira/browse/HBASE-7163 > Project: HBase > Issue Type: Sub-task > Reporter: Karthik Ranganathan > Assignee: Karthik Ranganathan > > This change saves 15% CPU on the client side per profiling. In using the > ConcurrentSkipListMap, we can do: > tableLocations.floorEntry(row).getValue() > instead of doing: > SortedMap<byte[], HRegionLocation> matchingRegions = > tableLocations.floorEntry(row).getValue(); > if (!matchingRegions.isEmpty()) { > HRegionLocation possibleRegion = > matchingRegions.get(matchingRegions.lastKey()); > } -- This message is automatically generated by JIRA.
