Class 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 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.
