    • Method Detail

      • bootstrapServers

        public KafkaSender.Builder bootstrapServers​(String bootstrapServers)
        Initial set of kafka servers to connect to, rest of cluster will be discovered (comma separated). Ex "192.168.99.100:9092" No default
        See Also:
        ProducerConfig.BOOTSTRAP_SERVERS_CONFIG

      • messageMaxBytes

        public KafkaSender.Builder messageMaxBytes​(int messageMaxBytes)
        Maximum size of a message. Must be equal to or less than the server's "message.max.bytes" and "replica.fetch.max.bytes" to avoid rejected records on the broker side. Default 500KB.

      • overrides

        public KafkaSender.Builder overrides​(Map<String,​?> overrides)
        By default, a producer will be created, targeted to bootstrapServers(String) with 0 required acks. Any properties set here will affect the producer config.

        Consider not overriding batching properties ("batch.size" and "linger.ms") as those will duplicate buffering effort that is already handled by Sender.

        For example: Reduce the timeout blocking from one minute to 5 seconds. 

        
 Map<String, String> overrides = new LinkedHashMap<>();
 overrides.put(ProducerConfig.MAX_BLOCK_MS_CONFIG, "5000");
 builder.overrides(overrides);
