Constructor.

Parameters
Name Description
data array

Optional. Data for populating the Message object.
↳ gc_rule GcRule

Garbage collection rule specified as a protobuf. Must serialize to at most 500 bytes. NOTE: Garbage collection executes opportunistically in the background, and so it's possible for reads to return a cell even if it matches the active GC expression for its family.
↳ value_type Type

The type of data stored in each of this family's cell values, including its full encoding. If omitted, the family only serves raw untyped bytes. For now, only the Aggregate type is supported. Aggregate can only be set at family creation and is immutable afterwards. If value_type is Aggregate, written data must be compatible with: * * value_type.input_type for AddInput mutations
