Subject [jira] [Updated] (LUCENE-4039) Add AddIndexesTask to Benchmark
Date Mon, 07 May 2012 13:26:50 GMT


Shai Erera updated LUCENE-4039:

    Attachment: LUCENE-4039.patch

Patch adds AddIndexesTask (+Test) and an addIndexs.alg.

Because of how Benchmark works, the input directory can only be a location on the file system
(and not e.g. RAMDirectory).

I haven't included yet PayloadProcessorProvider, I think it can be added separately.

> I was interested in measuring the performance of IndexWriter.addIndexes(Directory) vs.
IndexWriter.addIndexes(IndexReader). I wrote an AddIndexesTask and a matching .alg. The task
takes a parameter whether to use the IndexReader or Directory variants. I'll upload the patch
and describe the perf results.
