问题 I am fairly new to Python and MySQL. I am writing code that queries 60 different tables each containing records for each second in a five minute period. The code executes every five minutes. A few of the queries can reach 1/2 MB of data but most are in the 50 KB range. I am running on a workstation running Windows 7,64-bit using MySQL Connector/Python. I am testing my code using PowerShell windows but the code will eventually run as a scheduled task. The workstation has plenty of RAM (8 GB).
