Redis or Kafka Pub/Sub Service
I need a standard publisher/subscriber service created for users to subscribe to trading signals.
I currently have a fully functional solution that generates a trade signal and inserts the signal into a Postgres DB through GraphQL managed with Hasura. The signal is then sent to users of the iOS and Android apps through push notifications. This is all working well.
What I need now is new functionality that allows a user to subscribe via API to receive the trade signals (instead of receiving them via the mobile app). My thinking is to use an event in Hasura to fire every time a new signal is inserted in Postgres. The event triggers Redis or Kafka pub/sub to push the signal details to subscribers listening to the channel.
This architecture of the current system:
Azure VM
GraphQL
Hasura
Postgres
I need the Redis/Kafka components for the pub/sub model. I also need the ability to validate the subscriber is authorized to access the signals service. I also need the ability to easily create/activate new channels for users to subscribe.
Hi
My robust knowledge in Apache and Kafka will allow me to tackle your project and deliver it to you in no time.
In particular recent days I have built a solution using Apache Kafka and Flink to process big data stream from IoT devices.
The data generated by IoT devices were streamed to kafka topic and flik jobs were analyzed them.
And finally it were stored on AWS S3 to provide consumers.
I think my experience will help you.
Could we please discuss details?
Best regards,
Evgeny

Hello
I have a pretty good idea to a solution architecture that will fit your requirements while being both scalable and prepared for future expansion.
We should have a private chat about this to get started building a nice signal push integration.
I am a Danish software developer, living in Bulgaria (my wife’s home land). I have 10+ years of development experience, 5 of these on Azure.
