[GitHub] [pulsar] merlimat opened a new issue #13717: PIP-135: Include MetadataStore backend for Etcd

merlimat opened a new issue #13717:
URL: https://github.com/apache/pulsar/issues/13717


   ## Motivation
   
   Since all the pieces that composed the proposal in PIP-45 were finally merged
   and are currently ready for 2.10 release, it is now possible to add other
   metadata backends that can be used to support a BookKeeper + Pulsar cluster.
   
   One of the popular systems that is most commonly used in alternative of
   ZooKeeper is Etcd, thus it makes sense to have this as the first non-zookeeper
   implementation.
   
   ## Goal
   
   Provide a Etcd implementation for the `MetadataStore` API. This will allow
   users to deploy Pulsar clusters using Etcd service for the metadata and it will
   not require the presence of ZooKeeper.
   
   
   ## Implementation
   
    * Use the existing JEtcd Java client library for Etcd
    * Extends the `AbstractBatchedMetadataStore` class, in order to reuse the
      transparent batching logic that will be shared with the ZookKeeper
      implementation.
   
   Work in progress: https://github.com/apache/pulsar/pull/13225

   @hpvd We went through a different route here:
    * Provide a generic KV pluggable interface for Pulsar metadata access (`MetadataStore` APIs)
    * Implement Bookkeeper metadata access on top of Pulsar MetadataStore interfaces.
   
   BookKeeper is now able to use any of the Pulsar `MetadataStore` implementations.
