Key: LUCENE-1036
URL: https://issues.apache.org/jira/browse/LUCENE-1036
Project: Lucene - Java
Issue Type: Bug
Components: Index
Affects Versions: 2.3
Environment: AIX 5.3 Unix, Java 1.4,
lucene-core-2007-10-26_03-16-46.jar
Reporter: R Giles
Since the upcoming 2.3 version of Lucene has support for the
setRAMBufferSizeMB() method in Index Writer, I thought I would test its
performance. So, using my application that was built upon (and worked with)
Lucene 2.2, I downloaded the nightly build 2007-10-26_03-16-46 and rebuilt my
application with new code setting setRAMBufferSizeMB() from a properties file.
My test data resides in a database table of 30 columns holding 1.25 million
records. The good news is that performance is superior to Lucene 2.2. The
indexing completes in roughly 1/3 the time. The bad news is the Index
Writer.optimize() step now throws an java.lang.IllegalArgumentException.
I also run tests against various other tables. Indexing smaller amounts of
data did not throw the exception. Indexing largers amounts of data did throw
the exception. Note, I also tested nightly builds dating back to 2007-10-05.
