Xapian discuss - Nov 2009 - Is there any problem with multithread?

Hi, all:

	I am now using xapian in a web environment, I need multithread for writing the
database.
	So I wonder if there is any problem with multithread for writing?(all the
threads share a single WritableDatabase object)


-------------------------------
 
Best wishes from Ray.

Hi Ray,

WritableDatabase objects can only be used by a single thread.
Generally the best approach is to marshal all your writes into a
single structure (e.g. a queue or spool directory) and have a thread
or process to pick off items and write them to the database.

Is there any particular reason you want to have multiple writer threads?

cheers,
Tom

Hi, Tom:
