[CR #614717] When you change the value of the parallel_dsi parameter using the alter connection command or configure replication server command, Replication Server changes the existing configuration values of these parameters:
dsi_num_threads
dsi_num_large_xact_threads
dsi_serialization_method
dsi_sqt_max_cache_size
This may impact your replication performance.
Workaround: You should set the parallel_dsi parameter first, and then manually set the desired values for the above-mentioned parameters for your environment if you do not want to use the default values.
