Overview

Use a self hosted Kafka installation as a streaming source for AWS Lambda.

require 'aws-cdk-lib'

# With provisioned pollers and poller group for cost optimization
my_function = nil # AWSCDK::Lambda::Function
kafka_credentials = nil # AWSCDK::SecretsManager::ISecret

my_function.add_event_source(AWSCDK::LambdaEventSources::SelfManagedKafkaEventSource.new({
    bootstrap_servers: ["kafka-broker1.example.com:9092", "kafka-broker2.example.com:9092"],
    topic: "events-topic",
    secret: kafka_credentials,
    starting_position: AWSCDK::Lambda::StartingPosition::LATEST,
    authentication_method: AWSCDK::LambdaEventSources::AuthenticationMethod::SASL_SCRAM_512_AUTH,
    provisioned_poller_config: {
        minimum_pollers: 1,
