Create benchmark & approach for testing Lucene's near real-time performance
---------------------------------------------------------------------------
Key: LUCENE-2061
URL: https://issues.apache.org/jira/browse/LUCENE-2061
Project: Lucene - Java
Issue Type: Task
Components: Index
Reporter: Michael McCandless
Assignee: Michael McCandless
Priority: Minor
With the improvements to contrib/benchmark in LUCENE-2050, it's now
possible to create compelling algs to test indexing & searching
throughput against a periodically reopened near-real-time reader from
the IndexWriter.
Coming out of the discussions in LUCENE-1526, I think to properly
characterize NRT, we should measure net search throughput as a
function of both reopen rate (ie how often you get a new NRT reader
from the writer) and indexing rate. We should also separately measure
pure adds vs updates (deletes + adds); the latter is much more work
for Lucene.
This can help apps make capacity decisions... and can help us test
performance of pending improvements for NRT (eg LUCENE-1313,
LUCENE-2047).
