What happened?

To measure the TAT of database operations,
I installed Otel in Lambda Python with reference to the following.

I was able to measure the TAT of pymysql.
However, I can't properly measure the TAT of mysql-connector. (The TAT appears to be quite short..)

Research direction

Start by comparing the OpenTelemetry behavior for mysql-connector 9.3.0 and pymysql 1.1.1 in the reported AmazonLinux Lambda environment with Python 3.13. Reproduce the database operation traces and determine what is needed for mysql-connector TAT to match the expected duration.
