 # Go SDK Roadmap
 
-This roadmap is in progress. In the meantime, here are available resources:
+The Go SDK is currently experimental. As the first purely portable Beam SDK, the Go SDK is
constrained
+by the status of the [Beam Portabillity Framework](https://beam.apache.org/roadmap/portability/)
and the existence of
+portable runners.
 
- - JIRA: [sdk-go](https://issues.apache.org/jira/issues/?jql=project%20%3D%20BEAM%20AND%20component%20%3D%20sdk-go)
/ [BEAM-2083](https://issues.apache.org/jira/browse/BEAM-2083) |
- - Contact: [Henning Rohde](mailto:herohde@google.com)
+With that in mind present work on the Go SDK has the following goals:
+
+## Usability
+
+The Go SDK should not block users from writing the pipelines they need to run.
+
+* Support large elements [BEAM-4124](https://issues.apache.org/jira/browse/BEAM-4124)
+* Coder Registry to support complex user elements [BEAM-3306](https://issues.apache.org/jira/browse/BEAM-3306)
+
+## Performance
+
+Since the Go SDK has no official runner support at this time, this gives us the chance to
work on the performance
+of the SDK harness. When portable runners are ready, the Go SDK should be ready as well.
+
+* Reducing framework overhead on the SDK Harness side [BEAM-4726](https://issues.apache.org/jira/browse/BEAM-4726)
+* Tooling to enable and verify pipeline performance [BEAM-3612](https://issues.apache.org/jira/browse/BEAM-3612)
+* Measure the performance of the SDK at scale.
+
+## Integrating with the Go ecosystem
+
+The authors of the Go SDK intended to keep the parts of the language we love, and intend
for
+user pipelines to be as close to ordinary Go as possible, minimizing framework boiler plate
code.
+
+* Migrate to a vanity URL path [BEAM-4115](https://issues.apache.org/jira/browse/BEAM-4115)
+* Package versioning support [BEAM-5379](https://issues.apache.org/jira/browse/BEAM-5379)
+
+## Implement Portability features
+
+The following are dependant on the features being implemented in the Portability Framework.
+
+* Splitable DoFns (SDFs) for Scalable IO [BEAM-3301](https://issues.apache.org/jira/browse/BEAM-3301)
+  * This is the primary blocker for the Go SDK to scale to ingest large numbers of elements
in both batch and streaming.
+* Triggers and Timers [BEAM-3304](https://issues.apache.org/jira/browse/BEAM-3304)
+* Advanced WindowFns
+   * Session windows [BEAM-4152](https://issues.apache.org/jira/browse/BEAM-4152)
+   * Custom WindowFns (dependant on streaming Splitable DoFn support) [BEAM-2939](https://issues.apache.org/jira/browse/BEAM-2939)
+
+Without SDFs, IOs are always constrained to work on a single machine prior to a sharding
operation (like CoGroupByKey),
+which makes scalable IOs difficult to impossible to write.
+
+Otherwise, improving examples and documentation for devs and users alike is ongoing. 
+Contributions are welcome. Please contact the [dev list](mailto:dev@beam.apache.org?subject=%5BGo%20SDK%5D%20How%20can%20I%20help%3F)
+for assistance in finding a place to help out.
