Subject: Multiple concurrent async ops per IoCtx?
Date: Wed, 29 Aug 2012 12:57:09 +0200	[thread overview]
Message-ID: <k1ksi5$q2p$1@ger.gmane.org> (raw)


Dear list,

are Rados' IoCtx objects able to process multiple asynchronous 
operations at the same time, or is it necessary to wait for an operation 
to complete, before issuing a following operation?

I.e., can I do the following and expect it to work?

IoCtx ctx;
ctx.aio_read( ... read 1 ... );
ctx.aio_read( ... read 2 ... );
ctx.aio_read( ... read 3 ... );

... time passes ...

read 3 completes (e.g.)
read 1 completes
read 2 completes

TIA,
Cheers,

Rutger
