The parameters to CreateSink.
.. attribute:: parent
Required. The resource in which to create the sink: ::
"projects/[PROJECT_ID]" "organizations/[ORGANIZATION_ID]"
"billingAccounts/[BILLING_ACCOUNT_ID]"
"folders/[FOLDER_ID]" Examples: "projects/my-logging-
project", "organizations/123456789".
Optional. Determines the kind of IAM identity returned as
writer_identity in the new sink. If this value is omitted
or set to false, and if the sink's parent is a project, then
the value returned as writer_identity is the same group or
service account used by Logging before the addition of writer
identities to this API. The sink's destination must be in the
same project as the sink itself. If this field is set to
true, or if the sink is owned by a non-project resource such
as an organization, then the value of writer_identity will
be a unique service account used only for exports from the new
sink. For more information, see writer_identity in
LogSink][google.logging.v2.LogSink].
