Subject [jira] [Commented] (ACCUMULO-883) evaluate different thrift components for performance
Date Wed, 28 Nov 2012 15:32:58 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-883?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13505546#comment-13505546

Eric Newton commented on ACCUMULO-883:
--------------------------------------

I wrote a simple test, ran it three times.  I chose the update method, with a small {{Mutation}}
with 200 columns.

||{{TServer}}||{{TProtocol}}||Times|| || || Average||
|{{THaHs}}|{{TCompactProtocol}}|8504|5748|6477|6909
| |{{TBinaryProtocol}}|7503|5994|7093|6863
|{{ThreadedSelector}}|{{TCompactProtocol}}|7760|6170|5970|6633
| |{{TBinaryProtocol}}|9293|7708|6428|7809
|{{TThreadPool}}|{{TCompactProtocol}}|3648|4307|3379|3778
| |{{TBinaryProtocol}}|3508|3431|2931|3290

Presently we are using THaHs with an adaptive thread pool and the TCompactProtocol; I'm leaning
towards changing it to TThreadPool and TBinaryProtocol.

> Now that we've upgraded to Thrift 0.9, evaluate the fastest combination of TServer and
TProtocol on typical server hardware (many cores, lots of ram, fast networks).
