update readme with some more info, like this....
Installing Kafka Transaction driver
Create a Kafka / Eventstreams development instance. I used IBM's Cloud Pak for Integration's EventStreams
NOTE ** If you use Cloud Pak for Integration the quickstart deployment will not work.
Create a topic ... we use mosparz
Go to "connect to this cluster"
Generate a scram-user... we use scram-user as the user name
Copy the scram-user password and put it in the kafkaproducer.js file as 'sasl.password'
Download the .pem file
Get the Kafka listener and credentials, next to the scram you just generated. Should look like this:
kafka-dev-kafka-bootstrap-cp4i.marks-kafka2-1e3af63cfXXXXXXXX98d645120e18baf-0000.us-south.containers.appdomain.cloud:443
use this in the kafkaproducer.js as the metadata.broker.list
Clone(this repo) https://github.com/bmos299/TYSKafKaSample
run:
npm install node-rdkafka
replace the es-cert.pem in the directory with the one you downloaded above
You need to use node version 12.13.1 or you will see the error noted at the bottom of this readme
Use 2 terminal windows. in the first
run
node kafkaconsumer.js
NOTE: see below if you get a node error, sometimes the machine resets itself to a bad node version.
In the second terminal you have the option to run a single message or multiple
For a single message run
node kafkaproducer_single_message.js
For a several messages, run
node kafkaproducer_multiple_message.js
Once your run one of the producers you should see a message come across with some values and says "Message I want to send Barry"
This means you have successfully sent a message thru the Kafka queues and back.
