WL#3359: Decouple binary protocol from prepared statements
Affects: Benchmarks-3.0 — Status: Un-Assigned — Priority: Medium
Choosing to use MySQL prepared statements requires some compromises, such as an extra round trip for the "prepare" phase and a disabled query cache. In contrast, using MySQL's binary protocol for result sets is almost always good for performance. It should be possible to use the binary protocol without prepared statements. A client should be able to send a command COM_RESULTS_BINARY, requesting for all future result sets to be returned using the binary protocol. A similar command, COM_RESULTS_TEXT, would request that all future result sets use the text protocol. (Remark: no need to define a new command for that. We already have COM_SET_OPTION, currently used to enable/disable multi statements. We have 2^16-2 other possible option values left. We could use two of them for use_binary_result and use_text_result)
