Subject [jira] Commented: (LUCENE-1577) Benchmark of different in RAM realtime techniques
Date Tue, 11 Aug 2009 22:30:14 GMT

Mark Miller commented on LUCENE-1577:
-------------------------------------

bq. normally bulk indexing is done up front, and only a "trickle" of updates to doc are then
done for near real-time search

Really depends though I think - I would bet that many users that want real time are dealing
with a huge amount of updates at given times, and that type of thing seems likely to grow.
A lot of times its I think it could be much more than a trickle.

A lot of installations I have seen have certain times when a lot of documents are coming in
(certain times, certain days). Social Networking type sites likely see a constant stream of
updates at most times. Press releases have hotspots for release - newspaper data all comes
in at once in the morning - etc.
