Release 2.0.0

This is the first version after enter ASF incubator, thanks everyone for making it happen!

Upgrade from 1.x.x to 2.0.0

The transition from CeresDB to Apache HoraeDB introduces several breaking changes. To facilitate upgrading from older versions to v2.0.0, specific alterations are necessary.

Upgrade Steps

  1. Setup required envs
export HORAEDB_DEFAULT_CATALOG=ceresdb
  1. Update config

Etcd’s root should be configured both in horaedb and horaemeta

For horaedb

[cluster_deployment.etcd_client]
server_addrs = ['127.0.0.1:2379']
root_path = "/rootPath"

For horaemeta

storage-root-path = "/rootPath"
  1. Upgrade horaemeta

Horaedb will throw following errors, which is expected

2024-01-23 14:37:57.726 ERRO [src/cluster/src/cluster_impl.rs:136] Send heartbeat to meta failed, err:Failed to send heartbeat, cluster:defaultCluster, err:status: Unimplemented, message: "unknown service meta_service.MetaRpcService", details: [], metadata: MetadataMap { headers: {"content-type": "application/grpc"} }
  1. Upgrade horaedb

After all server upgraded, the cluster should be ready for read/write, and old data could be queried like before.
