Class NearRealtimeReaderTask
- java.lang.Object
-
- org.apache.lucene.benchmark.byTask.tasks.PerfTask
-
- org.apache.lucene.benchmark.byTask.tasks.NearRealtimeReaderTask
-
- All Implemented Interfaces:
Cloneable
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.
