Externaliz rarely used Libraries

[predic8]

We need to provide functionality based on prometheus, mongodb, opentelemetry, elastic, javascript ... . Then we can either include those libs or program adapters ourselves (Prometheus).

Idea:

Put the libraries as Jars into the lib after installing Membrane.
We use the libs as compile time but not as run time dependency.
An Interceptors init() Method checks if the lib is there and throws an ConfigruationException with a explanation how to install the jar into the lib folder.

Variations to discuss:

• Bundle some dependencies in a pom only git project e.g. membrane-operation with prometheus and opentelemetry, membrane-rhino, ...
• Publish the Jars as maven projects.
• Maybe some lib are optional. If prometheus is in the classpath the time interceptor publishes to prometheus otherwise not.

Some of the libs are:

• derby 3.5 MB
• kotlin std 1.8 MB
• rhino 1.3 MB
• soa model 1.2 MB
• jedis
• opentelemetry
• xmemcachd
• mongodb

What do you think?

What a about just delete the JARs from lib in the Dockerfile?

okhttp3 is included (separate HTTP stack impl, 2.94MB). can we switch from opentelemetry-exporter-sender-okhttp to opentelemetry-exporter-sender-jdk ?

[predic8]

think so
