Steve Blackmon commented on STREAMS-276:
----------------------------------------
re-opened because a lot of this refactoring and cleanup is still unfinished.
this should be the focus of the 0.5 round of provider "level up" work.
> Upgrade providers to supply StreamsDateTimeFormat, DocumentClassifier, and
> ActivityConverter implementations
> ------------------------------------------------------------------------------------------------------------

> Key: STREAMS-276
> URL: https://issues.apache.org/jira/browse/STREAMS-276
> Project: Streams
> Issue Type: Improvement
> Reporter: Steve Blackmon
> Assignee: Steve Blackmon
> Fix For: 0.5
>
>
> For each provider where the proposed re-factoring improvement is feasible,
> create sub-tasks to perform the following:
> 1) Add DocumentClassifier(s) capable of classifying each provider-specific
> type combination the provider expects to receive from all upstream end-points.
> 2) Add a test demonstrating one and only one of these Classifiers returns
> true across a set of example origin documents.
> 3) Add an ActivityConverter for each objectType/Verb combination the provider
> expects to emit. requiredClass should be one of String.class,
> ObjectNode.class, or a POJO which extends Serializable.
> 4) Add tests demonstrating that individual ActivityConverters are able to
> convert the set of example origin documents into activities with correct
> objectType/verb.
> 5) Add tests demonstrating that ActivityConverterProcessor is able to convert
> the set of example origin documents into activities with correct
> objectType/verb.
> 6) Add a StreamsDateTimeFormat for each non-RFC3339 date string the provider
> expects to receive.
> 7) Add a test demonstrating that StreamsJacksonMapper is able to convert
> matching date strings to DateTimes.
> 8) Mark legacy TypeConverters as Deprecated, or delete if they are now
> unmaintainable.
> 9) Mark legacy EventClassifiers as Deprecated, or delete if they are now
> unmaintainable.
> 10) Mark legacy StreamsMappers as Deprecated, or delete if they are now
> unmaintainable.
> For any provider where the proposed re-factoring improvement is not feasible,
> document why in the module README and/or create issues for whatever
> refactoring would be necessary to make that provider compatible with
> ActivityConverterProcessor.
