Class OpenIndexTask
- java.lang.Object
-
- org.apache.lucene.benchmark.byTask.tasks.PerfTask
-
- org.apache.lucene.benchmark.byTask.tasks.OpenIndexTask
-
- All Implemented Interfaces:
Cloneable
public class OpenIndexTask extends PerfTask
Open an index writer.
Other side effects: index writer object in perfRunData is set.
Relevant properties:merge.factor, max.buffered, max.field.length, ram.flush.mb [default 0].Accepts a param specifying the commit point as previously saved with CommitIndexTask. If you specify this, it rolls the index back to that commit on opening the IndexWriter.
