SymfonyDay Montreal 2026: Reconfiguring Symfony in real time with sidekicks (Symfony Blog)

SymfonyDay Montreal 2026 is scheduled for June 4, 2026, at L'Espace Quartier Latin (UQAM). Nicolas Grekas, Symfony Core team member, will present a talk on reconfiguring Symfony in real time using a new pattern called 'application sidekicks'. These are specialized PHP workers running outside the HTTP lifecycle via FrankenPHP, enabling dynamic reconfiguration without polling, TTLs, or redeployments. Use cases include Redis Sentinel discovery and dynamic feature flags. The event also includes a community networking drink sponsored by Pimcore.
