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, max.buffered,
max.field.length, ram.flush.mb [default 0],
[default true]
.
This task also supports a "writer.info.stream" property with the following
values:
- SystemOut - sets
IndexWriter.setInfoStream(java.io.PrintStream)
to System.out
.
- SystemErr - sets
IndexWriter.setInfoStream(java.io.PrintStream)
to System.err
.
- <file_name> - attempts to create a file given that name and sets
IndexWriter.setInfoStream(java.io.PrintStream)
to that file. If this
denotes an invalid file name, or some error occurs, an exception will be
thrown.
