Agneeswaran, I have tested and profiled ODBC using data from odbc-example and I can see that 1 million rows, 3 string columns each retrieved by ODBC in ~8 seconds on first run, and in less than ~5 seconds on second run.
Actually, ODBC driver always retrieving data by pages of size 1024 rows so it should be fast for the most use-cases. Please, check your configuration. In particular, if you've used odbc-example as a template, please, check that you have set proper value for the cfg.jvmMaxMem as the value in the example is low for a big number of records which can cause a lot of GC.
