Usage example
Inputs in, outputs out. Illustrative wiring, not a standalone deployment.
Supply aws.primary and aws.dr provider aliases. Configure producers and consumer rules separately; cross-region routing is optional. Configure provider requirements and credentials in your root module; check the documentation for all required inputs and version changes.
main.tf
module "events" {
source = "pomo-studio/event-bus/aws"
version = "~> 1.0"
name = "my-app-events"
enable_dr = true
enable_archive = true
enable_cross_region_routing = true
}Key inputs
- name
- enable_dr
- enable_schema_registry
- enable_archive
- enable_cross_region_routing
Useful outputs
- bus_name_primary
- bus_arn_primary
- bus_arn_dr
- cross_region_rule_arn
What you get
02
Event archive
Retain and replay historical traffic for recovery and debugging.
03
Schema registry
Document event contracts and reduce accidental breaking changes.
Patterns that use this component
- Materialized View
Precompute a read-optimized projection so queries stay fast without recomputing on every request.
- CQRS
Separate the write model from the read model so each can be shaped for its own job.
- Event-Driven Fan-out
Publish one event and let independent consumers react, without the producer knowing who they are.
