Constructor and Description
Kafka08JsonTableSink(String topic, Properties properties) Creates KafkaTableSink to write table rows as JSON-encoded records to a Kafka 0.8 topic with fixed partition assignment.
Kafka08JsonTableSink(String topic, Properties properties, org.apache.flink.streaming.connectors.kafka.partitioner.FlinkKafkaPartitioner<org.apache.flink.types.Row> partitioner) Creates KafkaTableSink to write table rows as JSON-encoded records to a Kafka 0.8 topic with custom partition assignment.
Kafka08JsonTableSink(String topic, Properties properties, org.apache.flink.streaming.connectors.kafka.partitioner.KafkaPartitioner<org.apache.flink.types.Row> partitioner) Deprecated. This is a deprecated constructor that does not correctly handle partitioning when producing to multiple topics. Use Kafka08JsonTableSink(String, Properties, FlinkKafkaPartitioner) instead.

Constructor Detail

Kafka08JsonTableSink

public Kafka08JsonTableSink(String topic,
                            Properties properties)

Creates KafkaTableSink to write table rows as JSON-encoded records to a Kafka 0.8 topic with fixed partition assignment.

Each parallel TableSink instance will write its rows to a single Kafka partition.

• If the number of Kafka partitions is less than the number of sink instances, different sink instances will write to the same partition.
• If the number of Kafka partitions is higher than the number of sink instance, some Kafka partitions won't receive data.

Parameters:

topic - topic in Kafka to which table is written

properties - properties to connect to Kafka

Kafka08JsonTableSink

public Kafka08JsonTableSink(String topic,
                            Properties properties,
                            org.apache.flink.streaming.connectors.kafka.partitioner.FlinkKafkaPartitioner<org.apache.flink.types.Row> partitioner)

Creates KafkaTableSink to write table rows as JSON-encoded records to a Kafka 0.8 topic with custom partition assignment.

Parameters:

topic - topic in Kafka to which table is written

properties - properties to connect to Kafka

partitioner - Kafka partitioner

Deprecated. This is a deprecated constructor that does not correctly handle partitioning when producing to multiple topics. Use Kafka08JsonTableSink(String, Properties, FlinkKafkaPartitioner) instead.

Creates KafkaTableSink to write table rows as JSON-encoded records to a Kafka 0.8 topic with custom partition assignment.

Parameters:

topic - topic in Kafka to which table is written

properties - properties to connect to Kafka

partitioner - Kafka partitioner
