I have a job that extracts result from DB query and put in tFileDelimetedOutput component. The problem here is query results in more than 2Lakh+ records and it's taking more than 1 and half hour to execute.
Is there any possibility to speedup the execution?
Could you please refer the below link which contains answer to similar query?

@Suneel - Did it help to resolve your query?
1) Try using optimizer hint on select query as it use the optimal execution plan or you can create index on the table.
2) Under Advance Setting Check Use Cursor checkbox.
@Ganshyam - I would not recommend the usage of optimizer hint to force a DB like Oracle to fine tune performance.
I agree with other two recommendations. From Oracle 10g onwards, Oracle DB is suggesting not to use optimizer hints unless required as Oracle optimizer is intelligent to select the best plan. I would suggest to check the Oracle ADDM report to see performance recommendations from Oracle database itself.
