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.
