Class NearRealtimeReaderTask

  • All Implemented Interfaces:

    public class NearRealtimeReaderTask
    extends PerfTask
    Spawns a BG thread that periodically (defaults to 3.0 seconds, but accepts param in seconds) wakes up and asks IndexWriter for a near real-time reader. Then runs a single query (body: 1) sorted by docdate, and prints time to reopen and time to run the search.
    WARNING: This API is experimental and might change in incompatible ways in the next release.
    It's also not generally usable, eg you cannot change which query is executed.
