This dependency is 18MB jar. I am not sure if it be worth it to bring such a big dependency as this jar also has to be bundled with hive-exec. We discussed this during the initial HLL implementation that this 3rd party dependency is big and replaced Int2ByteSortedMap with java TreeMap. If performance becomes a bigger concern we can consider bringing the jar, I think for now we can stick on to TreeMap and add just the optimizations. > HLL merges tempList on every add > > > Key: HIVE-19578 > URL: https://issues.apache.org/jira/browse/HIVE-19578 > Project: Hive > Issue Type: Bug >Reporter: Sergey Shelukhin >Assignee: Prasanth Jayachandran >Priority: Major > Attachments: Screen Shot 2018-05-16 at 15.29.12 .png > > > See comments on HIVE-18866; this has significant perf overhead after the > even bigger overhead from hashing is removed. !Screen Shot 2018-05-16 at > 15.29.12 .png! -- This message was sent by Atlassian JIRA (v7.6.3#76005)

Ran a quick benchmark with following scenarios
{code:java}
testHLLAddHive - Current Hive implementation that uses TreeMap for HLL Sparse
Register
testHLLAddInt2ByteSortedMap - TreeMap replaced with Int2ByteSortedMap for HLL
Sparse Regsiter
testHLLAddInt2ByteSortedMapPlusOpt - Int2ByteSortedMap + branch optimizations
in HLL add() inner loop{code}
{code:java}

[ https://issues.apache.org/jira/browse/HIVE-19578?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel=16478398#comment-16478398 ] Prasanth Jayachandran commented on HIVE-19578: -- HLL p value is also changing to 10 in HIVE-18079. With that the encoding switch threshold is only 153 but temp list's default size is 1024. So there is no point maintaining temp list. I will probably remove temp list as it will not help and can cut on additional branches. > HLL merges tempList on every add > > > Key: HIVE-19578 > URL: https://issues.apache.org/jira/browse/HIVE-19578 > Project: Hive > Issue Type: Bug >Reporter: Sergey Shelukhin >Assignee: Prasanth Jayachandran >Priority: Major > Attachments: Screen Shot 2018-05-16 at 15.29.12 .png > > > See comments on HIVE-18866; this has significant perf overhead after the > even bigger overhead from hashing is removed. !Screen Shot 2018-05-16 at > 15.29.12 .png! -- This message was sent by Atlassian JIRA (v7.6.3#76005)
