I am trying to fetch around 100000 records from an oracle db server. As fetch size of ojdbc driver by default is 10 it takes too much time to process these records. I tried to alter setFetchSize api of ResultSet but Talend Open Studio isn't supporting this change of code. What can I do to solve this problem?

In the advanced settings of the input components there is a use cursor / cursor size option. The name is very misleading but it does what you are looking for: set the fetchsize. I usually go with 100.
