I am not sure if a connection pool is the right pattern for my use case. What i
want is a cache for connections. Because eclipse-milo (respectively OPC-UA)
supports [subscription
|https://github.com/eclipse/milo/blob/master/milo-examples/client-examples/src/main/java/org/eclipse/milo/examples/client/SubscriptionExample.java]
on a OPC-UA Node value. So for my use case i have multiple subscriptions
(round about 100) which can use the same connection. The follow code shows the
routes in my application:
{code:java}
from("milo-client:opc.tcp://localhost:4344?node=RAW(nsu=urn:foo:bar;s=item-1)"
// ...
from("milo-client:opc.tcp://localhost:4344?node=RAW(nsu=urn:foo:bar;s=item-2)"
// ..
from("milo-client:opc.tcp://localhost:4345?node=RAW(nsu=urn:foo:bar;s=item-3)"{code}
In the example above i would have two connections. One connection per server.
So my suggestion would be to define a new SPI.

> Project: Camel
> Issue Type: Improvement
> Components: camel-milo
> Reporter: Claus Ibsen
> Priority: Major
> Fix For: 3.x

>
> Add an SPI interface to plugin a connection factory, so users can choose
> different implementations.
> This is what other component would do like messaging components.
> Then end users can build pooling or shared connection factories or whatnot.
