Could I connect to DB mutiply with Gatling JDBC feeder?

Hi, everyone.

I’ve been using Gatling for load testing our product. This time, we are trying to manage our user id in DB, so we start using JDBS feeder for getting user information, such as user Id and password.

Normally we test our product with 50K user and several load generators. I wonder that it would work well connecting DB multiply using JDBS feeder. Please share you guy’s experiences.

Detailed question.
If I use JDBS feeder with 3 load generator(docker container) of 1500 virtual users, how many connections happen during load test?
(I just want to know each generator(container) makes connections with bunch of virtual users. only one or same with thread counts(virtual user count)?)

Thank you.
