Hello all, In MySQL 5.1, I see that NDB exposes the HA_NEED_READ_RANGE_BUFFER flag as a table flag, and the result is that the functions handler::read_multi_range_first and handler::read_multi_range_next may possibly use the buffer passed in somehow. What is the contract here? How may the variable multi_range_buffer be used if a handler exposes HA_NEED_READ_RANGE_BUFFER?
