   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.

   maxInFlightRequestsPerConnection

   is the max.in.flight.requests.per.connection setting and represents the maximum number of unacknowledged request the client will send on a single connection before blocking. If this setting is set to be greater than 1 and there are failed sends, there is a risk of message re-ordering due to retries (if enabled).

   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.

   metricReporters

   is the metric.reporters setting. A list of classes to use as metrics reporters. Implementing the MetricReporter interface allows plugging in classes that will be notified of new metric creation. The JmxReporter is always included to register JMX statistics

   metricsNumSamples

   is the metrics.num.samples setting. The number of samples maintained to compute metrics.

   metricsSampleWindow

   is the metrics.sample.window.ms setting. The metrics system maintains a configurable number of samples over a fixed window size. This configuration controls the size of the window. For example we might maintain two samples each measured over a 30 second period. When a window expires we erase and overwrite the oldest window.

   monixSinkParallelism

   is the monix.producer.sink.parallelism setting indicating how many requests the KafkaProducerSink can execute in parallel.

   properties

   map of other properties that will be passed to the underlying kafka client. Any properties not explicitly handled by this object can be set via the map, but in case of a duplicate a value set on the case class will overwrite value set via properties.
