SWIP - SkyWalking Improvement Proposal

SWIP - SkyWalking Improvement Proposal, is an official document to propose a new feature and/or feature improvement, which are relative to end users and developers.

SkyWalking has been very stable since v9.x. We are getting over the rapid changing stage. The core concepts, protocols for reporting telemetry and query, 3rd party integration, and the streaming process kernel are very stable. From now(2024) on, SkyWalking community would focus more on improvement and controllable improvement. All major changes should be evaluated more seriously, and try as good as possible to avoid incompatible breaking changes.

What is considered a major change?

The catalogs of a major change are listed as follows

  • New Feature. A feature doesn’t exist for the latest version.
  • Any change of the network Interfaces, especially for Query Protocol, Data Collect Protocols, Dynamic Configuration APIs, Exporting APIs, AI pipeline APIs.
  • Any change of storage structure.

Q: Is Agent side feature or change considered a SWIP?

A: Right now, SWIP targets OAP and UI side changes. All agent side changes are pending on the reviews from the committers of those agents.
