KafkaProducerConfig

The Kafka Producer config.

For the official documentation on the available configuration options, see Producer Configs on kafka.apache.org.

bootstrapServers: is the bootstrap.servers setting and represents the list of servers to connect to.
acks: is the acks setting and represents the number of acknowledgments the producer requires the leader to have received before considering a request complete. See Acks.
bufferMemoryInBytes: is the buffer.memory setting and represents the total bytes of memory the producer can use to buffer records waiting to be sent to the server.
compressionType: is the compression.type setting and specifies what compression algorithm to apply to all the generated data by the producer. The default is none (no compression applied).
retries: is the retries setting. A value greater than zero will cause the client to resend any record whose send fails with a potentially transient error.
sslKeyPassword: is the ssl.key.password setting and represents the password of the private key in the key store file. This is optional for client.
sslKeyStorePassword: is the ssl.keystore.password setting, being the password of the private key in the key store file. This is optional for client.
sslKeyStoreLocation: is the ssl.keystore.location setting and represents the location of the key store file. This is optional for client and can be used for two-way authentication for client.
sslTrustStoreLocation: is the ssl.truststore.location setting and is the location of the trust store file.
sslTrustStorePassword: is the ssl.truststore.password setting and is the password for the trust store file.
batchSizeInBytes: is the batch.size setting. The producer will attempt to batch records together into fewer requests whenever multiple records are being sent to the same partition. This setting specifies the maximum number of records to batch together.
clientId: is the client.id setting, an id string to pass to the server when making requests. The purpose of this is to be able to track the source of requests beyond just ip/port by allowing a logical application name to be included in server-side request logging.
connectionsMaxIdleTime: is the connections.max.idle.ms setting and specifies how much time to wait before closing idle connections.
lingerTime: is the linger.ms setting and specifies to buffer records for more efficient batching, up to the maximum batch size or for the maximum lingerTime. If zero, then no buffering will happen, but if different from zero, then records will be delayed in absence of load.
maxBlockTime: is the max.block.ms setting. The configuration controls how long KafkaProducer.send() and KafkaProducer.partitionsFor() will block. These methods can be blocked either because the buffer is full or metadata unavailable.
maxRequestSizeInBytes: is the max.request.size setting and represents the maximum size of a request in bytes. This is also effectively a cap on the maximum record size.
partitionerClass: is the partitioner.class setting and represents a class that implements the org.apache.kafka.clients.producer.Partitioner interface.
receiveBufferInBytes: is the receive.buffer.bytes setting being the size of the TCP receive buffer (SO_RCVBUF) to use when reading data.
requestTimeout: is the request.timeout.ms setting, a configuration the controls the maximum amount of time the client will wait for the response of a request.
saslKerberosServiceName: is the sasl.kerberos.service.name setting, being the Kerberos principal name that Kafka runs as.
saslMechanism: is the sasl.mechanism setting, being the SASL mechanism used for client connections. This may be any mechanism for which a security provider is available.
securityProtocol: is the security.protocol setting, being the protocol used to communicate with brokers.
sendBufferInBytes: is the send.buffer.bytes setting, being the size of the TCP send buffer (SO_SNDBUF) to use when sending data.
sslEnabledProtocols: is the ssl.enabled.protocols setting, being the list of protocols enabled for SSL connections.
sslKeystoreType: is the ssl.keystore.type setting, being the file format of the key store file.
sslProtocol: is the ssl.protocol setting, being the SSL protocol used to generate the SSLContext. Default setting is TLS, which is fine for most cases. Allowed values in recent JVMs are TLS, TLSv1.1 and TLSv1.2. SSL, SSLv2 and SSLv3 may be supported in older JVMs, but their usage is discouraged due to known security vulnerabilities.
sslProvider: is the ssl.provider setting, being the name of the security provider used for SSL connections. Default value is the default security provider of the JVM.
sslTruststoreType: is the ssl.truststore.type setting, being the file format of the trust store file.
reconnectBackoffTime: is the reconnect.backoff.ms setting. The amount of time to wait before attempting to reconnect to a given host. This avoids repeatedly connecting to a host in a tight loop. This backoff applies to all requests sent by the consumer to the broker.
retryBackoffTime: is the retry.backoff.ms setting. The amount of time to wait before attempting to retry a failed request to a given topic partition. This avoids repeatedly sending requests in a tight loop under some failure scenarios.
metadataMaxAge: is the metadata.max.age.ms setting. The period of time in milliseconds after which we force a refresh of metadata even if we haven't seen any partition leadership changes to proactively discover any new brokers or partitions.
monixSinkParallelism: is the monix.producer.sink.parallelism setting indicating how many requests the KafkaProducerSink can execute in parallel.
