Description

Is there option for getting records from mysql as flat array rather than object. Something like this { contractor_id: 199 , contractor_name: ... } represented as [199,"Andrew","Banks", 88.92, 55,15].

I want to speed up reading of 75k records, now it takes 35 seconds I am wandering is array representation would be transferred to node faster as 35 seconds.

Research direction
The issue requests an option to return rows as flat arrays to improve performance. Investigate the current implementation of row parsing in lib/protocol/ResultSetHeader.js and related files. Consider adding a configuration option like 'rowsAsArray' in the connection or query options. Profile the overhead of object creation versus array creation for large result sets. See similar features in other MySQL drivers (e.g., node mysql2 has 'rowsAsArray' option).
