Go

The fluvio-go client is a community project put together by @avinassh.

It’s still under development but still very exciting!

 

Connecting

To connect to the fluvio cluster do:

f, err := fluvio.Connect()
 

Producer

To create a TopicProducer do:

producer, err := f.TopicProducer("hello-go")
 

Send

To send into a topic do:

val := fmt.Sprintf("(from Go) %d (%s)", i, time.Now().String())
err = producer.SendString(fmt.Sprintf("%d", i), val)
 

Consumer

To get a consumer, do:

partitionConsumer, err := f.PartitionConsumer("hello-go", 0)
 

Stream

To get a stream from the consumer do:

stream, err := partitionConsumer.Stream(fluvio.NewOffsetFromBeginning(0))
for {
     r, err := stream.Next()
     fmt.Printf("Got record: key=%s, value=%s\n", string(r.Key), string(r.Value))
}
 

Smart Streams

 

Filter

Create a consumer config with the wasm file and get the filtered stream:

wasmFile := "example/filter.wasm"
config, err := fluvioClient.ConsumerConfigWithWasmFilter(wasmFile)
stream, err := partitionConsumer.StreamWithConfig(fluvio.NewOffsetFromBeginning(0), config)
for {
     r, err := stream.Next()
     fmt.Printf("Got record: key=%s, value=%s\n", string(r.Key), string(r.Value))
}
