Package sarama is a pure Go client library for dealing with Apache Kafka (versions 0.8 and later). It includes a high-level API for easily producing and consuming messages, and a low-level API for controlling bytes on the wire when the high-level API is insufficient. Usage examples for the high-level APIs are provided inline with their full documentation. To produce messages, use either the AsyncProducer or the SyncProducer. The AsyncProducer accepts messages on a channel and produces them asynchronously in the background as efficiently as possible; it is preferred in most cases. The SyncProducer provides a method which will block until Kafka acknowledges the message as produced. This can be useful but comes with two caveats: it will generally be less efficient, and the actual durability guarantees depend on the configured value of `Producer.RequiredAcks`. There are configurations where a message acknowledged by the SyncProducer can still sometimes be lost. To consume messages, use Consumer or Consumer-Group API. For lower-level needs, the Broker and Request/Response objects permit precise control over each connection and message sent on the wire; the Client provides higher-level metadata management that is shared between the producers and the consumer. The Request/Response objects and properties are mostly undocumented, as they line up exactly with the protocol fields documented by Kafka at https://cwiki.apache.org/confluence/display/KAFKA/A+Guide+To+The+Kafka+Protocol Metrics are exposed through https://github.com/rcrowley/go-metrics library in a local registry. Broker related metrics: Note that we do not gather specific metrics for seed brokers but they are part of the "all brokers" metrics. Producer related metrics: Consumer related metrics:
Readme
Sarama is an MIT-licensed Go client library for Apache Kafka.
You might also want to look at the Frequently Asked Questions.
Sarama provides a "2 releases + 2 months" compatibility guarantee: we support the two latest stable releases of Kafka and Go, and we provide a two month grace period for older releases. However, older releases of Kafka are still likely to work.
Sarama follows semantic versioning and provides API stability via the standard Go module version numbering scheme.
A changelog is available here.
