Example does not work #7

Open hanusto opened 5 years ago

hanusto commented 5 years ago

I am trying to use this example with docker-compose up. Everything seems to be ok, but, when I add record into message table (manually via dbeaver client) nothing happens.

What is wrong? My expectation is that when something is inserted into MESSAGE table, new kafka event is emitted.

What's the output of docker-compose ps and docker-compose logs cdcservice? The CDC service needs to be running in order to publish messages inserted into the MESSAGE table.

Also, what's the value of DOCKER_HOST_IP?

hanusto commented 5 years ago

docker-compose logs cdcservice -> everything looks like good. CDC service is running.

WARNING: The DOCKER_HOST_IP variable is not set. Defaulting to a blank string.

I am using docker-compose as is.

Hi,currently everything works as expected. Mistake was between pc table and computer :). By the way, is there any documentation of implementation? For example what has to be done if someone want to use it. I am looking for documentation where I found explanation how it works, which Spring Boot properties have to be configured and why and so no.

@hanusto I expanded the README. Please review.

hanusto commented 5 years ago

Yes, it is great. And is there documentation where I can found how can I improve this code for example with AVRO integration? Which class I have to overload, or which configuration I have to change? Maybe I miss architecture overview or detail description how CDC is implemented. For example, now I have not MySQL db, but postgreSQL or MSSQL. So theoretically I can use the same approach but I have to change implementation of CDC service to read tx log for specific DB or use debezium engine, but how...

I can cooperate with you, for my opinion as someone who wants to use it some important notes are missing. I am thinking about using it in our project, but documentation is very high-level. Sorry for my feedback ;)

Docs definitely need work. Fixing this is a priority.

See this WIP manual on the CDC - http://eventuate.io/docs/manual/eventuate-tram/wip/

The CDC supports MySQL and postgres.

Wow! It is perfect. And why this is not linked in public website? Because it is in work in progress? But it is exactly what I am looking for :) Can I help you?

cer commented 5 years ago

@hanusto Sorry for the delayed response. Crazy work schedule. I've revised the docs. It would be great if you could take a look.

@hanusto Hey Tomas - Were you able to figure out how to integrate Avro with this?
