Dear all,
I've a question regarding buffers in rados (using the C++ API). I'm
allocating and using my own buffers, and would like to read and write
directly into and from them. I'm using a bufferlist consisting of
static_buffers, which are passed to Rados' aio_read and aio_write.
For aio_write, rados works as expected, i.e., the bufferlist is returned
as it was before the call. However, when doing aio_read, it seems that
the bufferlist is destroyed (not used) in the call, despite all the
buffers being static.
Is this expected behaviour? I read a thread "read/write on RADOS using
external buffer" from this mailing list from 2010, but wasn't able to
figure out whether rados does or doesn't support reading into
user-provided static_buffers.
Thanks in advance,
Cheers,
Rutger
