Use bulk copy-in to improve the performance of subscription
materialization.
When dsi_bulk_copy is
on, Replication Server uses bulk copy-in to materialize the subscriptions
if the number of insert commands in each transaction
exceeds dsi_bulk_threshold.
Note: In normal replication, bulk operation is disabled for
a table if autocorrection is on. However, in
materialization, bulk operation is applied even when autocorrection is
enabled, if dsi_bulk_threshold is
reached and the materialization is not a nonatomic subscription
recovering from failure.
