Function Mesh CRD configurations

This document lists CRD configurations available for Function Mesh. The CRD configurations for Function Mesh consist of Function configurations and common CRD configurations.

Function Mesh configurations​

The Function Mesh configurations are a combination of Pulsar Function configurations, Pulsar source configurations and Pulsar sink configurations. For details, see the following documentation.

This is a Function Mesh CRD example, which is used to submit the ElasticSearch sink connector and a Pulsar Functions to a Pulsar cluster.
