The KafkaConsumer iterator implementation +has been greatly simplified so that it just wraps consumer.poll(). The prior +implementation will remain available for a few more releases using the optional +KafkaConsumer config: `legacy_iterator=True` . This is expected to improve +consumer throughput substantially and help reduce heartbeat failures / group +rebalancing. + +Client +------ +* Send socket data via non-blocking IO with send buffer (dpkp / PR #1912) +* Rely on socket selector to detect completed connection attempts (dpkp / PR #1909) +* Improve connection lock handling; always use context manager (melor,dpkp / PR #1895) +* Reduce client poll timeout when there are no in-flight requests (dpkp / PR #1823) + +KafkaConsumer +------------- +* Do not use wakeup when sending fetch requests from consumer (dpkp / PR #1911) +* Wrap `consumer.poll()` for KafkaConsumer iteration (dpkp / PR #1902) +* Allow the coordinator to auto-commit on old brokers (justecorruptio / PR #1832) +* Reduce internal client poll timeout for (legacy) consumer iterator interface (dpkp / PR #1824) +* Use dedicated connection for group coordinator (dpkp / PR #1822) +* Change coordinator lock acquisition order (dpkp / PR #1821) +* Make `partitions_for_topic` a read-through cache (Baisang / PR #1781,#1809) +* Fix consumer hanging indefinitely on topic deletion while rebalancing (commanderdishwasher / PR #1782) + +Miscellaneous Bugfixes / Improvements +------------------------------------- +* Fix crc32c avilability on non-intel architectures (ossdev07 / PR #1904) +* Load system default SSL CAs if `ssl_cafile` is not provided (iAnomaly / PR #1883) +* Catch py3 TimeoutError in BrokerConnection send/recv (dpkp / PR #1820) +* Added a function to determine if bootstrap is successfully connected (Wayde2014 / PR #1876) + +Admin Client +------------ +* Add ACL api support to KafkaAdminClient (ulrikjohansson / PR #1833) +* Add `sasl_kerberos_domain_name` config to KafkaAdminClient (jeffwidman / PR #1852) +* Update `security_protocol` config documentation for KafkaAdminClient (cardy31 / PR #1849) +* Break FindCoordinator into request/response methods in KafkaAdminClient (jeffwidman / PR #1871) +* Break consumer operations into request / response methods in KafkaAdminClient (jeffwidman / PR #1845) +* Parallelize calls to `_send_request_to_node()` in KafkaAdminClient (davidheitman / PR #1807) + +Test Infrastructure / Documentation / Maintenance +------------------------------------------------- +* Add Kafka 2.3.0 to test matrix and compatibility docs (dpkp / PR #1915) +* Convert remaining `KafkaConsumer` tests to `pytest` (jeffwidman / PR #1886) +* Bump integration tests to 0.10.2.2 and 0.11.0.3 (jeffwidman / #1890) +* Cleanup handling of `KAFKA_VERSION` env var in tests (jeffwidman / PR #1887) +* Minor test cleanup (jeffwidman / PR #1885) +* Use `socket.SOCK_STREAM` in test assertions (iv-m / PR #1879) +* Sanity test for `consumer.topics()` and `consumer.partitions_for_topic()` (Baisang / PR #1829) +* Cleanup seconds conversion in client poll timeout calculation (jeffwidman / PR #1825) +* Remove unused imports (jeffwidman / PR #1808) +* Cleanup python nits in RangePartitionAssignor (jeffwidman / PR #1805) +* Update links to kafka consumer config docs (jeffwidman) +* Fix minor documentation typos (carsonip / PR #1865) +* Remove unused/weird comment line (jeffwidman / PR #1813) +* Update docs for `api_version_auto_timeout_ms` (jeffwidman / PR #1812) + + 1.4.6 (Apr 2, 2019) ################### |
