using DotPulsar;
using DotPulsar.Extensions;

const string myTopic = "persistent://public/default/mytopic";

// connecting to pulsar://localhost:6650
await using var client = PulsarClient.Builder().Build();

// consume messages
await using var consumer = client.NewConsumer(Schema.String)
    .SubscriptionName("MySubscription")
    .Topic(myTopic)
    .InitialPosition(SubscriptionInitialPosition.Earliest)
    .Create();

// produce a message
await using var producer = client.NewProducer(Schema.String).Topic(myTopic).Create();
