redirector.v1

key uniquely identifies the assignment of system_id to the cluster.

clusters that the system is assigned to.

system_id is the unique identifier of a device.

name of the cluster. The name can change over time as new clusters

are added or removed.

hosts in the cluster that the devices can connect to.

values contains the list of clusters associated with the region

Key uniquely identifies a Assignment instance to retrieve.

This value must be populated.

Time indicates the time for which you are interested in the data.

If no time is given, the server will use the time at which it makes the request.

Value is the value requested.

This structure will be fully-populated as it exists in the datastore. If

optional fields were not given at creation, these fields will be empty or

set to default values.

Time carries the (UTC) timestamp of the last-modification of the

Assignment instance in this response.

Time indicates the time for which you are interested in the data.

If no time is given, the server will use the time at which it makes the request.

Value is the value requested.

This structure will be fully-populated as it exists in the datastore. If

optional fields were not given at creation, these fields will be empty or

set to default values.

Error is an optional field.

It should be filled when there is an error in the GetSome process.

PartialEqFilter provides a way to server-side filter a GetAll/Subscribe.

This requires all provided fields to be equal to the response.

While transparent to users, this field also allows services to optimize internal

subscriptions if filter(s) are sufficiently specific.

TimeRange allows limiting response data to within a specified time window.

If this field is populated, at least one of the two time fields are required.

For GetAll, the fields start and end can be used as follows:

* end: Returns the state of each Assignment at end.

* Each Assignment response is fully-specified (all fields set).

* start: Returns the state of each Assignment at start, followed by updates until now.

* Each Assignment response at start is fully-specified, but updates may be partial.

* start and end: Returns the state of each Assignment at start, followed by updates

until end.

* Each Assignment response at start is fully-specified, but updates until end may

be partial.

This field is not allowed in the Subscribe RPC.

Value is a value deemed relevant to the initiating request.

This structure will always have its key-field populated. Which other fields are

populated, and why, depends on the value of Operation and what triggered this notification.

Time holds the timestamp of this Assignment’s last modification.

Operation indicates how the Assignment value in this response should be considered.

Under non-subscribe requests, this value should always be INITIAL. In a subscription,

once all initial data is streamed and the client begins to receive modification updates,

you should not see INITIAL again.

Time holds the timestamp of the last item included in the metadata calculation.

Operation indicates how the value in this response should be considered.

Under non-subscribe requests, this value should always be INITIAL. In a subscription,

once all initial data is streamed and the client begins to receive modification updates,

you should not see INITIAL again.

Count is the number of items present under the conditions of the request.
