Status

Current state: Accepted

Discussion thread: here

JIRA: KAFKA-4343

Released: 0.11.0.0 (WIP)

Please keep the discussion on the mailing list rather than commenting on the wiki (wiki discussions get unwieldy fast).

Motivation

Currently we don't expose information about whether a connector is a source or sink. This is useful when, e.g., categorizing connectors in a UI. Given naming conventions we try to encourage you might be able to determine this via the connector's class name, but that isn't reliable. We would also like to expose a Connector's version information.

Public Interfaces

We will add a `type` field to each element of the array that indicates whether the given Connector is a Source or SInk. e.g.:

 

 

Compatibility, Deprecation, and Migration Plan

  • This is purely an addition to the current API and is backwards compatible.

Rejected Alternatives

The current method to get this information is to use a heuristic (does a class contain SInk/Source?), or use a lookup table. Neither of which works in every case, or with dynamically loaded Connectors.
