Chris Riccomini commented on SAMZA-40:
--------------------------------------
bq. Support a programatic, code-level API for building, validating and
deploying jobs? Hopefully, this would make it possible to build higher-level
frameworks on top that could dynamically generate jobs. I don't know if I'd
ever want to do this but if the API is there, you never know what will spring
up.
This is something that's been floating around for a while, and I think could be
pretty useful. At minimum, it'd just be a builder API to generate a Config
object programmatically. This could then be used with the JobRunner to start a
job.
bq. Support for validation during build and during runtime initialization to
catch errors early.
+1 to this as well. We need to figure out a smart way to do it, but a lot of
class-not-found stuff could be caught immediately.
> Refactor Samza configuration

> Key: SAMZA-40
> URL: https://issues.apache.org/jira/browse/SAMZA-40
> Project: Samza
> Issue Type: Bug
> Components: container
> Affects Versions: 0.6.0
> Reporter: Chris Riccomini
> Labels: project
>
> Samza's configuration system has several problems that we need to resolved.
> * Want to auto-generate documentation based off of configuration.
> * Should support global defaults for a config property. Right now, we do
> config.getFoo.getOrElse() everywhere.
> * Should validate config up front, rather than thrown runtime exceptions
> randomly throughout the code.
> * We are mixing wiring and configuration together. How do other systems
> handle this?
> * We have fragmented configuration (anybody can define configuration). How do
> other systems handle this?
> * How to handle undefined configuration? How to make this interoperable with
> both Java and Scala (i.e. should we support Option in Scala)?
> * Should remain immutable.
> * Should remove implicits. It's just confusing.
> * Do we want to support complex types (list, map) for values, not just String?
> We need a design proposal for this.
