com.linkedin.databus2.relay.config.LogicalSourceStaticConfig
Extends the {@link WritableByteChannel} interface for use in chunked HTTP responses. The regularwrite operations create new chunks in the response. Two methods are added to support setting of header values in the trailer (aka footers). Footers are serialized when the channel is closed. @author cbotev
