   In fact, we are also trying to implement a batch delete function that can support the deletion of a large number of specified keys (including specifying multiple values in inPredicate)
   
   In your current implementation, if there are too many values in InPredicate (for example, tens of thousands), then each column must be looped through tens of thousands of conditions during query, which may be inefficient.
   
   Maybe you can discuss it with @yangzhg about it.
