Increase the default time on SQL queries

I have set up DB connection with tables which contains a following amounts of data:

When I want to create Periodic SQL invocation step for the whole table (select * from <table>), the creation for the huge table failed. When I click on Next button, the UI shows "The query could not be completed in 15.0 seconds.". Partial workaround for this issue is adding a limit for query e.g.

SELECT * FROM hugea LIMIT 10000

However, what if the customer wants to select the whole table.
