Features

User-visible or operator-visible capabilities that span multiple services and systems. These are the things a developer would say "Temporal can do X"; understanding them requires tracing through more than one place in the source.

Feature	What it lets users do
Workflows and activities	The core durable-execution model.
Nexus	Compose Temporal services across namespaces and clusters.
Scheduling	Cron-style scheduled workflow execution.
Search attributes and visibility	Indexed metadata and ListWorkflowExecutions queries.
Namespaces and multi-cluster	Tenant isolation and cross-cluster replication.
Worker versioning	Run multiple worker versions safely against one task queue.
Updates and queries	Synchronous-style interaction with running workflows.
Archival	Long-term storage of completed histories. (Lives under systems.)

Cross-cutting concerns

Some capabilities are not listed here because they are owned by a single subsystem:

• Persistence pluggability — see Systems → Persistence.
• Replication / XDC — see Systems → Replication.
• Authorization / TLS — see Security.

The split is somewhat arbitrary; if you don't find a topic here, check Systems.
