The source is on GitHub
Sparkwing lives at github.com/sparkwing-dev/sparkwing. Read it, build it, file issues, send PRs.
Heads up: this is v0
Sparkwing is in early development. The architecture is shifting week to week as it gets exercised against real workloads. The dispatch model, cache layer, and controller are all in active redesign.
There is no stable public API yet. Expect breaking changes between releases, including the CLI surface, the SDK, the pipeline grammar, and the on-disk formats. Pin versions, read release notes, and don't build production systems on top of internals until the surface settles.
Licensing
Sparkwing is likely going to land as OSS. For now it's released under the Elastic License 2.0 to give time to figure out the right long-term license before v1.
