Hi,
(how) does CDO support batch/bulk updates?
My application is getting master data daily in a night run.
The master data makes up to 70 percent of the total data.
How can I combine/load the data with CDO?
Currently we import the data as normal CDOs, which results in bad performance.
Is there a way to do a bulk insert/update?
Thanks in advance,
Joe

I know of no good way. All data instertions/modifications must happen in the scope of a transaction/commit for the
history to be correct.
Depending on various aspects, such as store type or DB vendor, it could be possible to tune for inserts. The DBStore,
for example, offers "WithRanges" mapping strategies for the auditing/branching modes with better insert/update
charecteristics. If you don't need auditing/branching make sure you switched them off.
