io.camunda.zeebe.logstreams.impl.serializer.DataFrameDescriptor

public final class DataFrameDescriptor
extends Object

Remnants of the dispatcher data framing. A 12 byte header starting with the frame length. The rest of the 12 bytes are unused. This is kept for backwards-compatibility reasons because LoggedEvent still expects this header.
