SFSObject expensive serialization size

Postby grhwood » 03 Jul 2015, 19:10

Hi,

I tested SFSObject serialization with an empty SFSObject and result in 3 bytes, but with empty byte[] it is 11bytes.

Here is my test code:

Code: Select all

SFSObject sfsObject = new SFSObject();
      sfsObject.putByteArray("1", new byte[] {});
      System.out.println(DefaultSFSDataSerializer.getInstance().object2binary(sfsObject).length);


Is it too much overhead ?

Thanks

Data types need to be identified and keys for each entry also take up a few bytes, depending on their string length.
If you want to squeeze every possible byte, you can put all of your data in an SFSArray which uses only indexes.

Additionally SFS2X can compress your packets when their size is greater than a certain threshold. By default it is 1024 byes. Applying compression to smaller data may not provide much advantage.
