This is the roadmap for the NATS Server. The purpose of this document is to give insight into some of the major features we plan to implement in the near future. It is a living document, and will change as goals and milestones are completed and new plans are made.
This project's release plan is kept updated on the wiki.
A master project release plan for all NATS projects can be found here
An Open-Source Planning Process is used to define the Roadmap.
This project is managed via GitHub milestones. Project Pages define the goals for each Milestone and identify current progress.
Upcoming features and bugfixes will be added to the relevant milestone. One or more Milestones will in turn be assigned to a release. If a feature or bugfix is not part of a milestone, it is currently unscheduled for implementation.
We will enable changes to a subset of configuration items on a running gnatsd without requiring
the instance to be restarted.
See Issue #338
We have done some work recently on exporting NATS monitoring data via Promethus. We plan to share this work in an upcoming release.
See Issue #345
We will improve/extend the auth interface(s) and configuration to support external auth endpoints.
See Issue #434
Multi-tenancy is a popular discussion topic, and one of the requirements we often hear is for the
ability to isolate/encapsulate the subject namespace by "tenant" (e.g. an account or organization).
For example, messages published on FOO.BAR by tenant A would not be visible to tenant B's
subscribers on FOO.BAR, and vice versa. We'd like to support this in an efficient and performant way.
See Issue #347 and Issue #348
Another multi-tenancy concern is the ability to limit the rate at which publishers can publish messages
to gnatsd. We've implemented this in a branch for an internal project but would like to make it public soon.
See Issue #346
Right now auto-unsubscribe is two operations: SUB foo 1 followed by UNSUB foo 1 1 (unsubscribe
after 1 message). For the sake of simplicity, efficiency and usability, we'd like to make that an
atomic protocol operation, optionally specifying the limit as part of the subscription e.g. SUB foo 1 1
See Issue #344
The original Ruby-based NATS server (now retired) was called nats-server, and the newer Go
version needed a unique name, hence gnatsd. We've recently gone through and attempted to
normalize names across all NATS projects to make them more predictable. Renaming gnatsd to
nats-server would align it more closely with the rest of the components in the NATS family.
See See Issue #226
Now that cluster auto-discovery is implemented for both clients and servers, NATS clusters can be dynamically expanded on demand. When this happens, it would be useful to (optionally) re-balance the client connections across the new (larger) cluster.
