Please take a look at my SPOI-5823 branch. I am almost done with the
enhancement and just finishing up some synchronization code. Note that
the branch is for review only and I am waiting for code migration to
Apache to commit my changes.

Sound pretty cool.
I have half baked patch for the thing I talked about. I think I can help
with your patch and/or extend it to something of what I have in mind.
Could you please point me to the right repo?

To add to Chetan comment, I am working on an enhancement that offloads
bufferserver spooling to disk to a separate thread. This thread will kick
in when only half (should it be configurable?) of memory blocks are left
available. This should further avoid possibility of I/O spikes.

The bufferserver writes pages to disk *only when* it runs out of memory to
hold them.
Can you elaborate where you see I/O spikes?

Folks,
I was wondering if it makes sense to have a functionality in which
bufferserver writes out data pages to disk in batches defined by
timeslice/application window.
This will allow flexible workloads and reduce I/O spikes (I understand
that
we have non-blocking I/O but it still would incur disk head costs).
Thoughts?
