Tenant context.

also: tenant context propagation · tenant_id propagation

Knowing which tenant a request belongs to and carrying that tenant ID through every service, query, event and background job.

the two-minute refresher

Extract the tenant once, at the edge (subdomain, token claim, header).
Propagate it in request context, message headers and job payloads.
Every query filters by it: one missing WHERE tenant_id leaks data across customers.
Background jobs and event consumers are where it most often gets lost.
