There will be five new configurations added for distributed workers:

• internalinter.requestworker.key.generation.algorithm
  • Purpose: the algorithm used to generate session keys
  • Type: string
  • Default: "HmacSHA256"
  • Importance: low
• internalinter.requestworker.key.size
  • Purpose: the size of generated session keys, in bits; if null, the default key size for the generation algorithm will be used (see the KeyGenerator Javadocs; specifically: "In case the client does not explicitly initialize the KeyGenerator (via a call to an init method), each provider must supply (and document) a default initialization.")
  • Type: int
  • Default: null
  • Importance: low
• internalinter.requestworker.key.rotation.intervalttl.ms
  • Purpose: how often to force a rotation of the internal key used for request validation, or 0 if forced rotation should never occur
  • Type: long
  • Default: 3600000 (one hour)
  • Importance: low
• internalinter.requestworker.signature.algorithm
  • Purpose: the algorithm to use to sign internal requests when sent from a follower worker to the leader
  • Type: string
  • Default: "HmacSHA256"
  • Importance: low
• internalinter.requestworker.verification.algorithms
  • Purpose: a list of supported algorithms for verifying internal requests that are received by the leader from a follower. This list must include the value provided for the internal.request.signature.algorithm property
  • Type: list
  • Default: "HmacSHA256"
  • Importance: low
