Hi,
Reinitiating the discussion and need inputs please.
How is the Talend generated code performed on Hadoop cluster (~200 nodes) processing 100 M rows with approx 10 columns. i googled and and couldn't find much details on Talend 6 or earlier version performance metrics. I am aware that Talend is just a code generator but, does anyone has any performance metrics of SCD Type 1 (On hive) and SCD Type2 (on Hbase) processing? 
Please share if anyone has any details or some references.
Thanks,
Ugandhar

Hi,I am trying to impliment the SCD type 2 through Hive,could someone pls guide me to understand these descriptions from the previopus post.
" SCD in Hadoop can be implemented using Hive ELT components.  My implementation has three parts:
-Change Data Capture (Using tELTHiveMap, tELTHiveInput(s) and tELTHiveOut).  The SCD table and staging table that contains today's records need to be left joined on the keys and if record exists compare the columns and write the appropriate code (Insert, Update/Insert). I wrote the results to a Delta Table.
- Now Apply the Inserts (New rows).
- Apply the type II updates (or SCD).  Insert Overwrite the rows that needs to be obsoleted. Add the new version needs to be updated.
