Project: Agroal
Issue Type: Feature Request
Components: pool
Reporter: Jesper Pedersen
Assignee: Luis Barreiro
Priority: Major
Fix For: 1.6
In scenarios where multiple pools access the same data source instance you may end up in
a situation where the combined number of max-pool-size is greater than the maximum number
of connections in the data source.
Introduce a pool-less mode, where the underlying connection is closed upon return to the
pool if the pool size is greater than min-pool-size.
This will allow you to configure Agroal to
{{.mode("pool-less").minSize(0).maxSize(1)}}
that only use 1 connection that is returned upon close. This is especially useful for
service-mesh scenarios where each service is short-lived, and process one transaction.
