Hi
In the very good performance guide made by Tobias, there are 2 options to achieve parallel replication. I have tried to understand the PROS and CONS between the 2 methods as described below.
What other PROS and CONS using either method are there?
Using Generic Tables Ranges
PRO:
Will give parallel replication
You can change the number of ranges for a table for which the replication process is running
Easy to define/customise in SLT
CON:
Not supported by all databases, i.e. DB2 is not supported
Does not support POOL tables
Defining Table Ranges Manually
PRO:
Will give parallel replication
Supports all databases
Supports all table types
CON:
Deep knowledge to data is required in order to define groupings/ranges for a table
More difficult to change the number of ranges for a table
