Hi,

I'm using PDI-CE-6.0, java 1.7 64 bit mixed mode, MySQL database innodb. if my question is relevent in PDI forum if related to MySQL forum, will delete this thread but i have a hope on your suggestions.

I am observing slowness issue while load data using Synchronize after merge with merge rows(diff). as per my POC when i kept NOLOCK on my target table then it is some what better. Could you please suggest if someone having the same issue with this step.

in below step my target table is prod_regn_1 and one of the extracting table also same for merge rows(diff) step. table lock will be occur while writing on target thats why i kept NOLOCK.
