Kem - I just assumed there was a seperate table for moving objects so this
is good to hear, but ... what about really slow movers? Will the MOP be
able to detect and track an object that crosses a chunk over the course of
6 months? 1yr? Put another way, do we need to assume some kind of small
but still significant (over the course of a release cycle) velocity for
objects in the main object table (especially leading up to DR1 since the
deep/moving pipelines won't have had very much time to discover/tell
eachother about such objects)?
Thanks,
Serge

Hi Jacek,
Your partitioning makes perfect sense, but there will be a few objects
which move more than quite a bit more than 1 chunk per night. But, I
think we were going to be keeping the moving obectsd in a separate table,
for this, as well as other, reasons.
cheers,
Kem

Hello,
Here is a brand new suggestion how to partition Object table
for the nightly processing use case:

Hope we will have time to talk about it during the telecon tomorrow.
Jacek
