- Update library v1.3.0 -> 1.5.0
* Improved broker connection error reporting with more useful information and
hints on the cause of the problem.
* Consumer: Propagate errors when subscribing to unavailable topics (#1540)
* Producer: Add `batch.size` producer configuration property (#638)
* Add `topic.metadata.propagation.max.ms` to allow newly manually created
topics to be propagated throughout the cluster before reporting them
as non-existent. This fixes race issues where CreateTopics() is
quickly followed by produce().
* Prefer least idle connection for periodic metadata refreshes, et.al.,
to allow truly idle connections to time out and to avoid load-balancer-killed
idle connection errors (#2845)
* Added `rd_kafka_event_debug_contexts()` to get the debug contexts for
a debug log line (by @wolfchimneyrock).
* Added Test scenarios which define the cluster configuration.
* Added MinGW-w64 builds (@ed-alertedh, #2553)
* `./configure --enable-XYZ` now requires the XYZ check to pass,
and `--disable-XYZ` disables the feature altogether (@benesch)
* Added `rd_kafka_produceva()` which takes an array of produce arguments
for situations where the existing `rd_kafka_producev()` va-arg approach
can't be used.
* Added `rd_kafka_message_broker_id()` to see the broker that a message
was produced or fetched from, or an error was associated with.
* Added RTT/delay simulation to mock brokers.
* Subscribing to non-existent and unauthorized topics will now propagate
errors `RD_KAFKA_RESP_ERR_UNKNOWN_TOPIC_OR_PART` and
`RD_KAFKA_RESP_ERR_TOPIC_AUTHORIZATION_FAILED` to the application through
the standard consumer error (the err field in the message object).
* Consumer will no longer trigger auto creation of topics,
`allow.auto.create.topics=true` may be used to re-enable the old deprecated
