Maximum number of
[DataStore][google.cloud.discoveryengine.v1beta.DataStore]s to return. If
unspecified, defaults to 10. The maximum allowed value is 50. Values above
50 will be coerced to 50.
If this field is negative, an INVALID_ARGUMENT is returned.
A page token
[ListDataStoresResponse.next_page_token][google.cloud.discoveryengine.v1beta.ListDataStoresResponse.next_page_token],
received from a previous
[DataStoreService.ListDataStores][google.cloud.discoveryengine.v1beta.DataStoreService.ListDataStores]
call. Provide this to retrieve the subsequent page.
When paginating, all other parameters provided to
[DataStoreService.ListDataStores][google.cloud.discoveryengine.v1beta.DataStoreService.ListDataStores]
must match the call that provided the page token. Otherwise, an
INVALID_ARGUMENT error is returned.
Required. The parent branch resource name, such as
projects/{project}/locations/{location}/collections/{collection_id}.
If the caller does not have permission to list
[DataStore][google.cloud.discoveryengine.v1beta.DataStore]s under this
location, regardless of whether or not this data store exists, a
PERMISSION_DENIED error is returned.
