builtin durable storage backend has been replaced with the following two backends:

  • builtin_local: A durable storage backend that doesn't support replication. It can't be used in a multi-node cluster. This backend is available in both open source and enterprise editions.
  • builtin_raft: A durable storage backend that uses Raft algorithm for replication. This backend is available only in the enterprise edition.

The following Prometheus metrics have been renamed:

  • emqx_ds_egress_batches -> emqx_ds_buffer_batches
  • emqx_ds_egress_batches_retry -> emqx_ds_buffer_batches_retry
  • emqx_ds_egress_batches_failed -> emqx_ds_buffer_batches_failed
  • emqx_ds_egress_messages -> emqx_ds_buffer_messages
  • emqx_ds_egress_bytes -> emqx_ds_buffer_bytes
  • emqx_ds_egress_flush_time -> emqx_ds_buffer_flush_time
