 | schemaLatestVersionCacheTTL | N | When using Schema Registry Avro serialization/deserialization. The TTL for schema caching when publishing a message with latest schema available. Default is 5 min | `5m` |
 | clientConnectionTopicMetadataRefreshInterval | N | The interval for the client connection's topic metadata to be refreshed with the broker as a Go duration. Defaults to `9m`. | `"4m"` |
 | clientConnectionKeepAliveInterval | N | The maximum time for the client connection to be kept alive with the broker, as a Go duration, before closing the connection. A zero value (default) means keeping alive indefinitely. | `"4m"` |
+| consumerFetchMin | N | The minimum number of message bytes to fetch in a request - the broker will wait until at least this many are available. The default is `1`, as `0` causes the consumer to spin when no messages are available. Equivalent to the JVM's `fetch.min.bytes`. | `"2"` |
 | consumerFetchDefault | N | The default number of message bytes to fetch from the broker in each request. Default is `"1048576"` bytes. | `"2097152"` |
+| channelBufferSize | N | The number of events to buffer in internal and external channels. This permits the producer and consumer to continue processing some messages in the background while user code is working, greatly improving throughput. Defaults to `256`. | `"512"` |
 | heartbeatInterval | N | The interval between heartbeats to the consumer coordinator. At most, the value should be set to a 1/3 of the `sessionTimeout` value. Defaults to "3s". | `"5s"` |
 | sessionTimeout | N | The timeout used to detect client failures when using Kafka’s group management facility. If the broker fails to receive any heartbeats from the consumer before the expiration of this session timeout, then the consumer is removed and initiates a rebalance. Defaults to "10s". | `"20s"` |
 | escapeHeaders | N | Enables URL escaping of the message header values received by the consumer. Allows receiving content with special characters that are usually not allowed in HTTP headers. Default is `false`. | `true` |
