Temporal Namespaces and Task Queues#

Namespaces and task queues are Temporal’s two primary organizational mechanisms. Namespaces provide isolation – separate history, retention, and access. Task queues route work to specific workers. Together, they determine where workflows run and how long their history is kept.

For the underlying architecture, see Introduction to Temporal.

Namespaces#

A namespace is a logical isolation boundary. Every workflow belongs to exactly one namespace. Namespaces provide history isolation (workflows cannot see across boundaries), independent retention policies, per-namespace search attributes, and scoped access control.
