Configuration

Firefly configuration can come from properties files, environment variables, and CLI arguments. CLI arguments have the highest priority.

Base

firefly.config.profile=pg
firefly.node.mode=standalone
firefly.node.name=firefly-standalone
firefly.node.roles=api,gateway,scheduler
firefly.plugins=metrics-prometheus

Admin HTTP

firefly.admin-http.host=127.0.0.1
firefly.admin-http.port=9710

Admin UI

FIREFLY_ADMIN_UI_HOST=127.0.0.1
FIREFLY_ADMIN_UI_PORT=9720
FIREFLY_ADMIN_API=http://127.0.0.1:9710

Metrics

firefly.metrics.prometheus.host=127.0.0.1
firefly.metrics.prometheus.port=9711

Gateway

firefly.executor.gateway.netty.port=9700
firefly.executor.registration.auto-create-definition=true

Security

firefly.security.jwt.secret=firefly-local-development-signing-secret-unsafe-change-me
firefly.security.jwt.issuer=firefly
firefly.security.jwt.access-token-ttl=PT1H

The local default account is admin/admin. Production deployments should rotate the password and replace the JWT secret.

Scheduler

firefly.scheduler.shard-count=32
firefly.scheduler.max-due-records-per-tick=10000
firefly.scheduler.max-idle-wakeup=PT0.5S

firefly.scheduler.shard-count is a cluster invariant and cannot be changed online after initialization.
