Thanks very much Paul, Could you like to tell me what time spent in your querying ten thousands of records from tables one time? In my test, when I query 10,000 records from a table which contains 17 millions records total, it will cost less than 1 second of querying INDEX, or cost more than 30 seconds of querying normal COLUMNs. I want to know query speed in larger table.
