TODO
- many oddities including permissions occasionally mixed up (still in spite of ACE fix)
- confusion about branches and versions
- Some sort of "deadlocks" occur on delete and insert when having an isolation level higher than read committed. These can hardly be "real" deadlocks as I only have one thread running :( Any hints?
- tests need to be run
my tests show that JDBCStore passes/fails the same tests of the other stores... so it seems in pretty good shape. What was its problem?
Hmmm. Have you tried the concurrent tests? Also, it really should not fail in any of the ordinary test... I have the file store to fail in null lock test only.
- ports to other major databases. I can do Oracle, but will need help with others
isn't plain SQL enough for what we need?
At least the DB schema needs to be adapted. We also need a common subset of SQL supported by all the major databases. This has to be determined practically, I guess. Additionally, there *always* is the difference in blob handling between Oracle and the rest of the world.
To my complete DISMAY performance measurements showed no significant difference to the "untuned" version. *Sigh*
bummer... maybe the database schema needs a redesign?
The schema looks good to me, but I will start a new thread discussing it.
how do you run those performance tests?
As I said, just puttting, reading, and finally deleting a large directory tree. Have a look at the quoted parted of the message you replied to.
But you are right, I only tested this with MS SQLServer with MS JDBC driver. So, I have to do proper tests later.
sorry for the ton of questions, but I'm trying to get up to speed so that I can help more effectively.
Thanks for all those questions :)
Oliver
