> StreamSpec constructors in the ExecutionEnvironments
> ----------------------------------------------------
>
> Key: SAMZA-1096
> URL: https://issues.apache.org/jira/browse/SAMZA-1096
> Project: Samza
> Issue Type: Bug
> Reporter: Jake Maes
> Assignee: Jake Maes
> Fix For: 0.13.0
>
>
> SAMZA-1075 added the notion of a StreamSpec for describing streams to be
> created, validated, or simply used in a samza application.
> SAMZA-1073 added the basic Fluent API but directly instantiated StreamSpecs,
> which puts undue burden on the user.
> This task is to provide a basic constructor(s) in the ExecutionEnvironments
> to enable users to easily create a StreamSpec.
> Goals:
> 1. ExecutionEnvironment can influence the type of StreamSpec returned. For
> example a TestExecutionEnvironment might return a StreamSpec corresponding to
> an in-memory Collection stream, whereas the production ExecutionEnvironments
> would return a more scalable option, such as a Kafka StreamSpec.
> 2. We want 1 constructor which derives everything (type, properties, system,
> etc) from config.
> 3. We want to be able to add convenience constructors for various types, like
> streamFromFile() for a file impl. These can be added later, but the
> foundational work should support it.
