Subject [jira] [Commented] (DBUTILS-78) Add asynchronous batch, query, and update calls
Date Mon, 26 Sep 2011 14:37:26 GMT


Simone Tripodi commented on DBUTILS-78:

Thanks a lot for your prompt help William, very appreciated! :)

I proposed to use {{ExecutorService}} due to my not big experience with concurrent APIs, and
just reading basic javadoc I found that {{ExecutorService}} is the more primitive element
to run {{Callable}}s.
So apologize for having reopened the issue, I thought that just providing {{ExecutorService}}
would reduce code redundancies.

Anyway, since you submitted the initial patch (I guess you had a usecase for having submitted
it), if you can confirm that the new version of {{AsyncQueryRunner}} would be really useful,
I would be pleased to apply it.

Many thanks in advance!

DBUTILS-78_Future.patch, DBUTILS-78_Future_v2.patch, async.diff, pom.diff
> I propose a new QueryRunner class, AsyncQueryRunner, which changes the return type of
batch, query, and update methods. Instead of returning their respective return types, the
methods would return a RunnableFuture. This would allow callers to either execute the RunnableFuture
in a thread or via an CompletionService like the ExecutorCompletionService.
