very interesting syntax sugar related to that takeIf

What
In order to allow us to utilize all available sockets by default in speed mode we need to stop setting a default concurrency value of 1.
How
New source configs will not set concurrency value by default, letting the connector decide based on mode and available sockets.
Existing connections will migrate where connections that were previously set to any number other than the default 1 will behave as if not set.
The new optional field will allow an admin to define a max value as before.
effective concurrency is
Users who didn't set anything manually would run with concurrency = number of sockets, which is the optimal value for performance. For example 8 concurrent select queries running over 8 sockets.
