当用 Flink SQL 写入 kafka 的时候如何指定分区策略呢？其实 Flink SQL 本身是提供有 sink.partitioner 参数的，详细可以查看官网 https://nightlies.apache.org/flink/flink-docs-release-1.14/docs/connectors/table/kafka/#sink-partitioner
| sink.partitioner | optional | ‘default’ | String | Output partitioning from Flink’s partitions into Kafka’s partitions. Valid values aredefault: use the kafka default partitioner to partition records.fixed: each Flink partition ends up in at most one Kafka partition.round-robin: a Flink partition is distributed to Kafka partitions sticky round-robin. It only works when record’s keys are not specified.Custom FlinkKafkaPartitioner subclass: e.g. 'org.mycompany.MyPartitioner'.See the following |
