Purpose of this producer is used for Google Cloud Managed Kafka load test. Hence you could use that for sizing and cost estimation

Use this dataflow consumer to achieve best performance and retrieve stats information.

Quickstart

Prerequisites, the Google Auth Server

1. install the server

./authserver install

2. start the server

./authserver start

Go Program build

code you need to change before build

• topicName is the Kafka Topic you want to send to
• "bootstrap.servers": "bootstrap.dingo-kafka.us-central1.managedkafka.du-hast-mich.cloud.goog:9092", replace the value accordingly to your Kafka server
• Optional
  • numPublishers number of Kafka publishers concurrently
  • numDataGenThreads number of data generation threads, only increase the number if data pool is constantly empty which may potentially affect the publishing performance
  • numWorkers better to keep this same as numPublishers, this only pull the data from the pool and fill the data chanel, which is dedicated for each publisher

1. init the project (you only need to do that once)

make init

2. build the Golang code

make build

3. Dump the data You should be able see a binary named main in the project root directory, simply run it ./main or make run
