Hi All,
I have different source DBs like SQL, Oracle Netezza to download data and on daily / Monthly basis I have to download very huge numbers of records
e.g 8-20 crores. Which take longer time to download data from these source system.
What are the Query optimization techniques to faster download data from these source systems.
In Oracle we tried parallel 8 query which is downloading data faster .
e.g select /*+ parallel(8) */
In same way is there any options available in SQL and Netezza (NZSQL).
Regards,
Sachin
