> The current version of OraOOP seems to perform very low from performance POV when --direct
mode turned on (regardless if the partitioned feature is turned of).
> Just as a baseline from the current trunk version:
> Inserting 100.000 rows into a 800 column wide Oracle table has 400-600 kb/sec with direct
mode on my cluster, while the standard oracle driver can produce up to 1.2-1.8 mb/sec. (depending
on the number of mappers, batch size).
> Inserting 1.000.000 rows into the same table goes up to 800k-1mb/sec with OraOOP, however
with the standard Oracle connector it's around 3.5mb/sec.
> It seems OraOOP export needs a thorough review and some fixing.
