Various small improvements to contrib/benchmark
-----------------------------------------------
Key: LUCENE-1139
URL: https://issues.apache.org/jira/browse/LUCENE-1139
Project: Lucene - Java
Issue Type: Improvement
Components: contrib/benchmark
Reporter: Michael McCandless
Assignee: Michael McCandless
Priority: Minor
Fix For: 2.4
Attachments: LUCENE-1139.patch
I've worked out a few small improvements to contrib/benchmark:
* Refactored the common code in Open/CreateIndexTask that sets the
configuration for the IndexWriter. This also fixes a bug in
OpenIndexTasks that prevented you from disabling flushing by RAM.
* Added a new config property for LineDocMaker:
doc.reuse.fields=true|false
which turns on/off reusing of Field/Document by LineDocMaker.
This lets us measure performance impact of sharing Field/Document
vs not, and also turn it off when necessary (eg if you have your
own consumer that uses private threads).
* Added merge.scheduler & merge.policy config options.
* Added param for OptimizeTask, which expects an int and calls
optimize(maxNumSegments) with that param.
* Added param for CloseIndex(true|false) -- if you pass false that
means close the index, aborting any running merges
