```
    Specifies the ZooKeeper connection string in the form hostname:port where host and port are the host and port of a ZooKeeper server. To allow connecting through other ZooKeeper nodes when that ZooKeeper machine is down you can also specify multiple hosts in the form hostname1:port1,hostname2:port2,hostname3:port3. The server may also have a ZooKeeper chroot path as part of it's ZooKeeper connection string which puts its data under some path in the global ZooKeeper namespace. If so the consumer should use the same chroot path in its connection string. For example to give a chroot path of /chroot/path you would give the connection string as hostname1:port1,hostname2:port2,hostname3:port3/chroot/path.

  - getBrokers
```
public String getBrokers()
```
  - setBrokers
```
public void setBrokers(String brokers)
```
    This is for bootstrapping and the producer will only use it for getting metadata (topics, partitions and replicas). The socket connections for sending the actual data will be established based on the broker information returned in the metadata. The format is host1:port1,host2:port2, and the list can be a subset of brokers or a VIP pointing to a subset of brokers.
    This option is known as metadata.broker.list in the Kafka documentation.
  - getProducerType
```
public String getProducerType()
```
  - setProducerType
```
public void setProducerType(String producerType)
```
    This parameter specifies whether the messages are sent asynchronously in a background thread. Valid values are (1) async for asynchronous send and (2) sync for synchronous send. By setting the producer to async we allow batching together of requests (which is great for throughput) but open the possibility of a failure of the client machine dropping unsent data.
  - getCompressionCodec
```
public String getCompressionCodec()
```
  - setCompressionCodec
```
public void setCompressionCodec(String compressionCodec)
```
    This parameter allows you to specify the compression codec for all data generated by this producer. Valid values are "none", "gzip" and "snappy".
  - getCompressedTopics
```
public String getCompressedTopics()
```
  - setCompressedTopics
```
public void setCompressedTopics(String compressedTopics)
```
    This parameter allows you to set whether compression should be turned on for particular topics. If the compression codec is anything other than NoCompressionCodec, enable compression only for specified topics if any. If the list of compressed topics is empty, then enable the specified compression codec for all topics. If the compression codec is NoCompressionCodec, compression is disabled for all topics
  - getMessageSendMaxRetries
```
public Integer getMessageSendMaxRetries()
```
  - setMessageSendMaxRetries
```
public void setMessageSendMaxRetries(Integer messageSendMaxRetries)
```
    This property will cause the producer to automatically retry a failed send request. This property specifies the number of retries when such failures occur. Note that setting a non-zero value here can lead to duplicates in the case of network errors that cause a message to be sent but the acknowledgement to be lost.
  - getRetryBackoffMs
```
public Integer getRetryBackoffMs()
```
  - setRetryBackoffMs
```
public void setRetryBackoffMs(Integer retryBackoffMs)
```
    Before each retry, the producer refreshes the metadata of relevant topics to see if a new leader has been elected. Since leader election takes a bit of time, this property specifies the amount of time that the producer waits before refreshing the metadata.
  - getTopicMetadataRefreshIntervalMs
```
public Integer getTopicMetadataRefreshIntervalMs()
```
  - setTopicMetadataRefreshIntervalMs
```
public void setTopicMetadataRefreshIntervalMs(Integer topicMetadataRefreshIntervalMs)
```
    The producer generally refreshes the topic metadata from brokers when there is a failure (partition missing, leader not available...). It will also poll regularly (default: every 10min so 600000ms). If you set this to a negative value, metadata will only get refreshed on failure. If you set this to zero, the metadata will get refreshed after each message sent (not recommended). Important note: the refresh happen only AFTER the message is sent, so if the producer never sends a message the metadata is never refreshed
  - getSendBufferBytes
```
public Integer getSendBufferBytes()
```
  - setSendBufferBytes
```
public void setSendBufferBytes(Integer sendBufferBytes)
```
    Socket write buffer size
  - getRequestRequiredAcks
```
public short getRequestRequiredAcks()
```
  - setRequestRequiredAcks
```
public void setRequestRequiredAcks(short requestRequiredAcks)
```
    This value controls when a produce request is considered completed. Specifically, how many other brokers must have committed the data to their log and acknowledged this to the leader? Typical values are (0, 1 or -1): 0, which means that the producer never waits for an acknowledgement from the broker (the same behavior as 0.7). This option provides the lowest latency but the weakest durability guarantees (some data will be lost when a server fails). 1, which means that the producer gets an acknowledgement after the leader replica has received the data. This option provides better durability as the client waits until the server acknowledges the request as successful (only messages that were written to the now-dead leader but not yet replicated will be lost). -1, The producer gets an acknowledgement after all in-sync replicas have received the data. This option provides the greatest level of durability. However, it does not completely eliminate the risk of message loss because the number of in sync replicas may, in rare cases, shrink to 1. If you want to ensure that some minimum number of replicas (typically a majority) receive a write, then you must set the topic-level min.insync.replicas setting. Please read the Replication section of the design documentation for a more in-depth discussion.
  - getRequestTimeoutMs
```
public Integer getRequestTimeoutMs()
```
  - setRequestTimeoutMs
```
public void setRequestTimeoutMs(Integer requestTimeoutMs)
```
    The amount of time the broker will wait trying to meet the request.required.acks requirement before sending back an error to the client.
  - getQueueBufferingMaxMs
```
public Integer getQueueBufferingMaxMs()
```
  - setQueueBufferingMaxMs
```
public void setQueueBufferingMaxMs(Integer queueBufferingMaxMs)
```
    Maximum time to buffer data when using async mode. For example a setting of 100 will try to batch together 100ms of messages to send at once. This will improve throughput but adds message delivery latency due to the buffering.
  - getQueueBufferingMaxMessages
```
public Integer getQueueBufferingMaxMessages()
```
  - setQueueBufferingMaxMessages
```
public void setQueueBufferingMaxMessages(Integer queueBufferingMaxMessages)
```
    The maximum number of unsent messages that can be queued up the producer when using async mode before either the producer must be blocked or data must be dropped.
  - getQueueEnqueueTimeoutMs
```
public Integer getQueueEnqueueTimeoutMs()
```
  - setQueueEnqueueTimeoutMs
```
public void setQueueEnqueueTimeoutMs(Integer queueEnqueueTimeoutMs)
```
    The amount of time to block before dropping messages when running in async mode and the buffer has reached queue.buffering.max.messages. If set to 0 events will be enqueued immediately or dropped if the queue is full (the producer send call will never block). If set to -1 the producer will block indefinitely and never willingly drop a send.
  - getBatchNumMessages
```
public Integer getBatchNumMessages()
```
  - setBatchNumMessages
```
public void setBatchNumMessages(Integer batchNumMessages)
```
    The number of messages to send in one batch when using async mode. The producer will wait until either this number of messages are ready to send or queue.buffer.max.ms is reached.
  - getSerializerClass
```
public String getSerializerClass()
```
  - setSerializerClass
```
public void setSerializerClass(String serializerClass)
```
    The serializer class for messages. The default encoder takes a byte[] and returns the same byte[]. The default class is kafka.serializer.DefaultEncoder
  - getKeySerializerClass
```
public String getKeySerializerClass()
```
  - setKeySerializerClass
```
public void setKeySerializerClass(String keySerializerClass)
```
    The serializer class for keys (defaults to the same as for messages if nothing is given).
  - getOffsetsStorage
```
public String getOffsetsStorage()
```
  - setOffsetsStorage
```
public void setOffsetsStorage(String offsetsStorage)
```
    Select where offsets should be stored (zookeeper or kafka).
  - isDualCommitEnabled
```
public Boolean isDualCommitEnabled()
```
  - setDualCommitEnabled
```
public void setDualCommitEnabled(Boolean dualCommitEnabled)
```
    If you are using "kafka" as offsets.storage, you can dual commit offsets to ZooKeeper (in addition to Kafka). This is required during migration from zookeeper-based offset storage to kafka-based offset storage. With respect to any given consumer group, it is safe to turn this off after all instances within that group have been migrated to the new version that commits offsets to the broker (instead of directly to ZooKeeper).
  - copy
