Hi,

Just wondering if there is something available to test from the index update effort.

Thanks,

Gary

Hi Dimitar,

Thanks for the info.  I see that adding a document changes the database indexing status to off.  A query to locate a document by node value in a database with 54k documents went from 3 seconds to 4 minutes.

I can image it’s difficult to balance performance in different aspects of the application and maintain database stability at the same time.  For the past couple of weeks I’ve tested query performance on a half dozen databases and BaseX queries were almost always quickest and never crashed even when running with lower memory.

Depending on how things go with my research I may be able to help test the index updating feature when you are ready for that.

Thanks,

Gary

Subject: Updates and indexing

Hi,

I was reading a thread in the mail list from Oct 2010 which states updates are not indexed:

https://mailman.uni-konstanz.de/pipermail/basex-talk/2010-October/000707.html

Is this still the case with version 6.5.1?   When talking of updates does that mean whole document replacement (or deletion) as well as XQuery updates?

Thanks for any clarification,

gary
