Examples

Adds a data history connection to a target Digital Twins instance with the $Default Event Hub consumer group.

az dt data-history connection create adx -n {instance_name} --cn {time_series_database_connection_name} --adx-cluster-name {adx_cluster_name} --adx-database-name {adx_database_name} --eventhub {event_hub} --eventhub-namespace {event_hub_namespace}

Adds a data history connection to a target Digital Twins instance using a User Assigned Identity associated with the Digital twin with the $Default Event Hub consumer group.

az dt data-history connection create adx -n {instance_name} --cn {time_series_database_connection_name} --adx-cluster-name {adx_cluster_name} --adx-database-name {adx_database_name} --eventhub {event_hub} --eventhub-namespace {event_hub_namespace} --mi-user-assigned {resource_id}

Adds a data history connection to a target Digital Twins instance with a custom Azure Data Explorer table name and Event Hub consumer group.

az dt data-history connection create adx -n {instance_name} --cn {time_series_database_connection_name} --adx-cluster-name {adx_cluster_name} --adx-database-name {adx_database_name} --adx-property-events-table {adx_property_events_table_name} --eventhub {event_hub} --eventhub-namespace {event_hub_namespace} --eventhub-consumer-group {event_hub_consumer_group}

Adds a data history connection to a target Digital Twins instance integrating with an Event Hub and Azure Data Explorer instances in different resource groups and subscriptions from the target instance.

az dt data-history connection create adx -n {instance_name} --cn {time_series_database_connection_name} --adx-cluster-name {adx_cluster_name} --adx-database-name {adx_database_name} --adx-resource-group {adx_resource_group} --adx-subscription {adx_subscription} --eventhub {event_hub} --eventhub-namespace {event_hub_namespace} --eventhub-resource-group {event_hub_resource_group} --eventhub-subscription {event_subscription}

Adds a data history connection to a target Digital Twins instance with the $Default Event Hub consumer group and skip the role assignment prompts.

az dt data-history connection create adx -n {instance_name} -y --cn {time_series_database_connection_name} --adx-cluster-name {adx_cluster_name} --adx-database-name {adx_database_name} --eventhub {event_hub} --eventhub-namespace {event_hub_namespace}

Adds a data history connection to a target Digital Twins instance with the $Default Event Hub consumer group and enables record property and item removals. An additional column will be added to the table used for storing updates to properties of twins and relationships (defaulted to AdtPropertyEvents).

az dt data-history connection create adx -n {instance_name} --cn {time_series_database_connection_name} --adx-cluster-name {adx_cluster_name} --adx-database-name {adx_database_name} --eventhub {event_hub} --eventhub-namespace {event_hub_namespace} --adx-record-removals true
