| <h1>Apache Flink 1.3.2 Released</h1> |
| <p><i></i></p> |
| |
| <article> |
| <p>05 Aug 2017</p> |
| |
| <p>The Apache Flink community released the second bugfix version of the Apache Flink 1.3 series.</p> |
| |
| <p>This release includes more than 60 fixes and minor improvements for Flink 1.3.1. The list below includes a detailed list of all fixes.</p> |
| |
| <p>We highly recommend all users to upgrade to Flink 1.3.2.</p> |
| |
| <div class="alert alert-warning"> |
| Important Notice: |
| |
| <p>A user reported a bug in the FlinkKafkaConsumer |
| (<a href="https://issues.apache.org/jira/browse/FLINK-7143">FLINK-7143</a>) that is causing |
| incorrect partition assignment in large Kafka deployments in the presence of inconsistent broker |
| metadata. In that case multiple parallel instances of the FlinkKafkaConsumer may read from the |
| same topic partition, leading to data duplication. In Flink 1.3.2 this bug is fixed but incorrect |
| assignments from Flink 1.3.0 and 1.3.1 cannot be automatically fixed by upgrading to Flink 1.3.2 |
| via a savepoint because the upgraded version would resume the wrong partition assignment from the |
| savepoint. If you believe you are affected by this bug (seeing messages from some partitions |
| duplicated) please refer to the JIRA issue for an upgrade path that works around that.</p> |
| |
| <p>Before attempting the more elaborate upgrade path, we would suggest to check if you are |
| actually affected by this bug. We did not manage to reproduce it in various testing clusters and |
| according to the reporting user, it only appeared in rare cases on their very large setup. This |
| leads us to believe that most likely only a minority of setups would be affected by this bug.</p> |
| </div> |
| |
| <p>Notable changes:</p> |
| |
| <ul> |
| <li>The default Kafka version for Flink Kafka Consumer 0.10 was bumped from 0.10.0.1 to 0.10.2.1.</li> |
| <li>Some default values for configurations of AWS API call behaviors in the Flink Kinesis Consumer |
| were adapted for better default consumption performance: 1) <code>SHARD_GETRECORDS_MAX</code> default changed |
| to 10,000, and 2) <code>SHARD_GETRECORDS_INTERVAL_MILLIS</code> default changed to 200ms.</li> |
| </ul> |
| |
| <p>Updated Maven dependencies:</p> |
