When an index contains unnecessary data, the I/O to read this data and memory to cache it reduce the performance and scalability of the server. To tune queries for InnoDB tables, create an appropriate set of indexes on each table. Follow these ...

This causes it to use the mysql_use_result() C API function to retrieve the result set, which places less of a load on the client (but more on the server). Is it reasonable that it should return so many rows? If not, correct the query and try again.
