Bin2DataStreamer

Overview

Bin2DataStreamer implements a data streamer that uses a proprietary binary format for streaming data across the network. This format is compatible with the Delphi version of Data Abstract.

The Bin2DataStreamer is provided as an alternative to the existing BinDataStreamer, which, of course, is still supported for backward compatibility.

Benefits

  • New streaming format: better defined and much more efficient, especially for large data transfer.
  • Reduction of network traffic: SendReducedDelta mode, pre-validation of the stream structure and non-transmission of null values.
  • Bin2DataStreamer has additional optimization for cases when OnBeforeFieldValueSerialization and OnWriteFieldValue events are not used. Changing of BufferSize property may also increase performance.
