@KRISHNA A scheduled script and a saved search would probably be your best bet - See SuiteAnswer ID 70816 as an example

@theglenjamin I already have a suitescript that deletes the records using a saved search results. As I have more than 100K records it is taking more time to delete the records. I am looking for something that speeds up this deleting process not taking 2 to 3 days to save my time.

@KRISHNA Got it, I thought you were using the mass update feature and using a scheduled script instead would likely have better performance. Other than reviewing the script to see if any changes can be made to increase performance (such as possibly using a map reduce script type) I'm not sure what else could be done short of purchasing Suitecloud Plus for multiple processors and queues. That would also increase the performanceof the csv imports.
