Enhancements
#10568 Add shutdown counter information to
emqx ctl listeners
command#10571 Do not emit useless crash report when EMQX stops. Previously, when EMQX (and
emqx_topic_metrics
in particular) stopped and removed underlying tables, some messages were still being handled and crashed.#10588 Increase the time precision of trace logs from second to microsecond. For example, change from
2023-05-02T08:43:50+00:00
to2023-05-02T08:43:50.237945+00:00
.#10623 Renamed
max_message_queue_len
tomax_mailbox_size
in theforce_shutdown
configuration. Old name is kept as an alias, so this change is backward compatible.#10417 Improve get config performance by eliminating temporary references.
#10525 Reduce resource usage per MQTT packet handling.
#10528 Reduce memory footprint in hot code path.
#10573 Improved performance of Webhook bridge when using synchronous query mode. This also should improve the performance of other bridges when they are configured with no batching.
#10591 Improve the configuration of the limiter.
- Simplify the memory representation of the limiter configuration.
- Make sure the node-level limiter can really work when the listener's limiter configuration is omitted.
#10625 Simplify limiter configuration.
- Reduce the complexity of the limiter's configuration.
e.g. now users can use
limiter.messages_rate = 1000/s
to quickly set the node-level limit for the message publish. - Update the
configs/limiter
API to suit this refactor.
- Reduce the complexity of the limiter's configuration.

emqx_connector_http
ifAuthorization
