Collection threadsafe ?
Hi,
some newbie questions about xindice.
Can I use a collection, which was created with
DatabaseManager.getCollection in more than one thread?
And is my assumption, that creating the collection is relative slow, correct?
Regards
Martin

And to reopen it, if a operation fails. Apparently a collection does not
survive a restart of the database :-)

Not that slow. I was considering, if I should close a collection immediately
after querying a resource and reopen it, if needed or reuse a collection,
which results in a slightly more complicated progamming logic.

It should work, but you need to be careful that you don't call the close
method at the wrong time.
