Gagan Goel	d4d0ebdf5d	Improve batch inserts. ... 1) Instead of making dbrm calls to writeVBEntry() per block, we make these calls per batch. This can have non-trivial reductions in the overhead of these calls if the batch size is large. 2) In dmlproc, do not deserialize the whole insertpackage, which consists of the complete record set per column, which would be wasteful as we only need some metadata fields from insertpackage here. This is only done for batch inserts at the moment, this should also be applied to single inserts.	2020-05-10 19:38:06 -04:00
