Hello Multitenancy World!
summary
Astra migrated from single-tenant to multitenant by containerizing Spring/Tomcat applications, running them on Kubernetes in GCP, and automating provisioning with Terraform and FluxCD. Tenant isolation is implemented either via a tenant_id column or separate databases, Kafka topics are namespaced by tenant, and Keycloak plus a permissions matrix enable per-tenant feature rollout; onboarding is one command but provisioning still takes ~30 minutes. They built a dynamic Mongo connector (context-holder with cached connections) and GitOps pipelines that work, while issues remain with timezoneed schedulers, Spring context restarts, and noisy-tenant resource limits.
