Package org.apache.lucene.benchmark.byTask.tasks

Class CreateIndexTask

java.lang.Object

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) to System.out.
• SystemErr - sets IndexWriterConfig.setInfoStream(java.io.PrintStream) to System.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.
