Rising Whale

Playing around with Streaming and Rising Wave

Quickstart

Project setup

This project is managed through invoke.

$ poetry install
$ inv --list

and serve yourself :)

Setting up Rising Wave

$ cd docker
$ docker-compose up --build -d

After this, you should be able to access:

• Rising Wave UI: http://127.0.0.1:5691/
• Grafana: http://127.0.0.1:3001/
• Minio: http://127.0.0.1:9400/
  • Username: hummockadmin
  • Password: hummockadmin
• Prometheus: http://127.0.0.1:9500/
• Redpanda Console: http://127.0.0.1:8080/

And connect to a local postgres instance with the arguments in .env suffixed with RISING_WAVE.

Example setup

I'm assuming you already configured Rising Wave following the previous step!

As this in still under active development, there is not a single neat clean tidy entrypoint/CLI for this.

$ python src/rising_whale/kafka/main.py

After running this:

1. You should have 1 topic created
2. You should have 1 message in the topic
3. The message's schema should be registered in RedPanda schema registry

Next:

1. Connect to RisingWave database through your favorite SQL Client
2. Allow Rising Wave to read from the topic and query from it:

CREATE SOURCE IF NOT EXISTS rising_whale_purchase
WITH (
   connector='kafka',
   topic='rising-whale-input',
   properties.bootstrap.server='message_queue:29092',
) FORMAT PLAIN ENCODE AVRO (
   schema.registry = 'http://message_queue:8081'
);

select *, _rw_kafka_timestamp from rising_whale_purchase;
