Parameters:

rmqConnectionConfig - The RabbitMQ connection configuration RMQConnectionConfig.

queueName - The queue to publish messages to.

schema - A SerializationSchema for turning the Java objects received into bytes

Method Detail

setLogFailuresOnly

public void setLogFailuresOnly(boolean logFailuresOnly)

Defines whether the producer should fail on errors, or only log them. If this is set to true, then exceptions will be only logged, if set to false, exceptions will be eventually thrown and cause the streaming program to fail (and enter recovery).

Parameters:

logFailuresOnly - The flag to indicate logging-only on exceptions.

open

public void open(org.apache.flink.configuration.Configuration config)
          throws Exception

Specified by:

open in interface org.apache.flink.api.common.functions.RichFunction

Overrides:

open in class org.apache.flink.api.common.functions.AbstractRichFunction

Throws:

Exception

invoke

public void invoke(IN value)

Called when new data arrives to the sink, and forwards it to RMQ.

Specified by:

invoke in interface org.apache.flink.streaming.api.functions.sink.SinkFunction<IN>

Specified by:

invoke in class org.apache.flink.streaming.api.functions.sink.RichSinkFunction<IN>

Parameters:

value - The incoming data

close

public void close()

Specified by:

close in interface org.apache.flink.api.common.functions.RichFunction

Overrides:
