}

A specification of a set of documents to listen to.

This type is not used in any activity, and only used as part of another schema.

Fields

documents: Option<DocumentsTarget>

A target specified by a set of document names.

read_time: Option<String>

Start listening after a specific read_time.

The client must know the state of matching documents at this time.

query: Option<QueryTarget>

A target specified by a query.

resume_token: Option<String>

A resume token from a prior TargetChange for an identical target.

Using a resume token with a different target is unsupported and may fail.

target_id: Option<i32>

A client provided target ID.

If not set, the server will assign an ID for the target.

Used for resuming a target without changing IDs. The IDs can either be client-assigned or be server-assigned in a previous stream. All targets with client provided IDs must be added before adding a target that needs a server-assigned id.

once: Option<bool>

If the target should be removed once it is current and consistent.
