- org.apache.lucene.benchmark.byTask.tasks.PerfTask
-
- org.apache.lucene.benchmark.byTask.tasks.CreateIndexTask

- All Implemented Interfaces:
Cloneable
public class CreateIndexTask extends PerfTask
Create an index.
Other side effects: index writer object in perfRunData is set.
Relevant properties:merge.factor (default 10), max.buffered (default no flush), compound (default true), ram.flush.mb [default 0], merge.policy (default org.apache.lucene.index.LogByteSizeMergePolicy), merge.scheduler (default org.apache.lucene.index.ConcurrentMergeScheduler), concurrent.merge.scheduler.max.thread.count and concurrent.merge.scheduler.max.merge.count (defaults per ConcurrentMergeScheduler), default.codec
.This task also supports a "writer.info.stream" property with the following values:
- SystemOut - sets
IndexWriterConfig.setInfoStream(java.io.PrintStream)
toSystem.out
. - SystemErr - sets
IndexWriterConfig.setInfoStream(java.io.PrintStream)
toSystem.err
. - <file_name> - attempts to create a file given that name and sets
IndexWriterConfig.setInfoStream(java.io.PrintStream)
to that file. If this denotes an invalid file name, or some error occurs, an exception will be thrown.
