Temporal Worker

Temporal Worker is a role for Temporal service used for hosting any components responsible for performing background processing on the Temporal cluster.

Replicator

Replicator is a background worker responsible for consuming replication tasks generated by remote Temporal clusters and pass it down to processor, so they can be applied to local Temporal cluster.

Quickstart for localhost development

1. Start Temporal development server for active zone:

   make start-cdc-active
   

2. Start Temporal development server for standby(passive) zone:

   make start-cdc-standby
   

3. Connect two Temporal clusters:

   tctl --ad 127.0.0.1:7233 adm cl upsert-remote-cluster --frontend_address "localhost:8233"
   tctl --ad 127.0.0.1:8233 adm cl upsert-remote-cluster --frontend_address "localhost:7233"
   

4. Create global namespaces

   tctl --ns sample namespace register --gd true --ac active --cl active standby
   

5. Failover between zones:

   Failover to standby:

   tctl --ns sample namespace update --ac standby
   

   Failback to active:

   tctl --ns sample namespace update --ac active
   

Archiver

Archiver is used to handle archival of workflow execution histories. It does this by hosting a Temporal client worker and running an archival system workflow. The archival client gets used to initiate archival through signal sending. The archiver shards work across several workflows.
