------------------------------------
Hi Zheng,
1. I never ran it before. That's a lot of warnings. I'll use it from now on in
my editor.
2. Ah yes it needs a bit of refactoring. I was trying to do a quick and dirty
fix to get the job done.
To give you some background, on my project we are using JdbcTemplates with dbcp
and running multiple queries concurrently. We for instance import data from 1
load table into multiple partitions at the same time. So those threads start
roughly at the same time and look roughly the same making this an issue.
2.1 Sounds like a good idea.
2.2 Would you prefer Context.generateExecutionId() way of doing it? it
theoretically can still collide although extremely unlikely.
Using a UUID prevents this completely (although at a price). Either way is fine
by me.
Would you like me to make these changes or would this be part of the larger
issue?
Thanks.
