Apache Pulsar Go Client Library
A Go client library for the Apache Pulsar project.
Goal
This projects is developing a pure-Go client library for Pulsar that does not depend on the C++ Pulsar library.
Once feature parity and stability are reached, this will supersede the current CGo based library.
Requirements
- Go 1.11+
Status
Check the Projects page at https://github.com/apache/pulsar-client-go/projects for tracking the status and the progress.
Usage
Import the client library:
import "github.com/apache/pulsar-client-go/pulsar"Create a Producer:
client, err := pulsar.NewClient(pulsar.ClientOptions{
URL: "pulsar://localhost:6650",
})
defer client.Close()
producer, err := client.CreateProducer(pulsar.ProducerOptions{
Topic: "my-topic",
})
_, err = producer.Send(context.Background(), &pulsar.ProducerMessage{
Payload: []byte("hello"),
})
defer producer.Close()
if err != nil {
fmt.Println("Failed to publish message", err)
}
fmt.Println("Published message")Create a Consumer:
client, err := pulsar.NewClient(pulsar.ClientOptions{
URL: "pulsar://localhost:6650",
})
defer client.Close()
consumer, err := client.Subscribe(pulsar.ConsumerOptions{
Topic: "my-topic",
SubscriptionName: "my-sub",
Type: pulsar.Shared,
})
defer consumer.Close()
msg, err := consumer.Receive(context.Background())
if err != nil {
log.Fatal(err)
}
fmt.Printf("Received message msgId: %#v -- content: '%s'\n",
msg.ID(), string(msg.Payload()))Contributing
