Consider event sourcing projections #1819

Open Swoorup opened 3 years ago

Swoorup commented 3 years ago

This is both a question/request. One of the requirements of event sourcing application is projection/subscription to create read models.

Could edgedb provide mechanism to subscribe from a specific row in the events (append only table) and push changes to the consumers. That would eliminate the need for polling or message brokers like kafka.

We are planning to add support for event pub/sub via a configurable trigger system.

Is this feature still planned? Is that the proper issue/discussion to track or is there another one?

elprans commented 10 months ago

Yes, EdgeDB 3.0 supports triggers, however a general pub/sub mechanism has not been implemented yet. On the TODO list.
