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), max.field.length (default 10,000 tokens), max.field.length, 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) .
