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), 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)
.
This task also supports a "writer.info.stream" property with the following
