Method propose_metadata

nodedb-cluster/tests/common/test_node.rs:295–301

Propose a `MetadataEntry` directly to the metadata Raft group on this node. Fails if this node is not the group-0 leader. This is the path integration tests use to inject replicated DDL without bringing up a pgwire client. Production uses the same underlying `RaftLoop::propose_to_metadata_group`.

        &self,
        entry: &nodedb_cluster::MetadataEntry,

        let bytes = nodedb_cluster::encode_entry(entry)?;
        Ok(self.raft_loop.propose_to_metadata_group(bytes)?)
    }
