From a4af3415e833525ee33a3ac41e409a1b96c2f985 Mon Sep 17 00:00:00 2001 From: Matteo Merli Date: Tue, 17 Mar 2026 09:29:54 -0700 Subject: [PATCH 1/2] Add Etcd metadata store provider plugin Etcd metadata store support is being removed from Pulsar core (PIP-462). This module provides it as an external plugin for users who still need it. The plugin can be loaded by adding the shaded jar to the Pulsar classpath and setting the system property: -Dpulsar.metadata.store.providers=org.apache.pulsar.metadata.impl.EtcdMetadataStoreProvider
