faas-bb's Issues

template http mode: parse input on content type

Add testing example

This isn't necessarily a Function example.

Question: how can we work around the function.handler namespace incompatibility with use outside OpenFaaS, with minimal setup?

Still some warmup is needed on first invoke

Still, some warmup is needed on the first invoke.
Figure out a way to fix this externally through some OpenFaaS mechanism or from the bb side. The latter is better because it requires no user configuration.

Add Function example establishing db connection

Add Function example establishing db connection:

• Pool database connections
• Database connection pool persists between requests
• Database pooling should be established if there isn't one

Support handler for request to manually set up response headers

Some use cases: https://developer.mozilla.org/en-US/docs/Glossary/Response_header

We could either configure using environment variable or a different handler name like req-handler. The latter is more likely, because the difference is explicit by looking at the handler ns file.

Add template using of-watchdog HTTP mode

Compare streaming and http templates

Support multiple handlers on different HTTP methods

Explore using multimethods for distinction.

Support copying local .m2 cache to image

A use case is persisting a shared .m2 cache between containers so that:

• We don't need to warm up the first time the container is run by fetching deps.
• When provisioning many replicas at the same time, we don't compromise the network.

Add wrap-edn-body and wrap-edn-response

Depending on the situation, we can pass either an "accept" environment variable to the Function or as a header.

Add Function example addressing log issue when printing to stdout

Add Function example addressing log issue when printing to stdout, when using of-watchdog streaming mode.

Bundle mvn deps in docker build to avoid faas replica warmup on first invokation
