efficient way of doing SCD on huge tables

Hi,

 

I'm having a data source table which contains 30 million records. On a given day, there could changes done only around 1000 records. I need to write a SCD type 2 table flow to fetch these changes. Can anyone please suggest the efficient way of reading the data from a huge table.

 

Currently I'm using tmysqlSCD for loading scd type 2 table

Quick thought: Bulk Load a certain no.of records into Temp table and use this temp table as source.

Parallelization might also do the trick. Can you try and post your findings?
