Changing a specific thread pool can be done by setting its type and

The `queue_size` allows to control the size of the queue of pending
requests that have no threads to execute them. By default, it is set to
`-1` which means its unbounded. When a request comes in and the queue is
full, the `reject_policy` parameter can control how it will behave. The
default, `abort`, will simply fail the request. Setting it to `caller`
will cause the request to execute on an IO thread allowing to throttle
the execution on the networking layer.

==== `blocking`
The `blocking` pool allows to configure a `min` (defaults to `1`) and
`size` (defaults to the number of cores times 5) parameters for the
number of threads.
It also has a backlog queue with a default `queue_size` of `1000`. Once
the queue is full, it will wait for the provided `wait_time` (defaults
to `60s`) on the calling IO thread, and fail if it has not been
executed.
