Batch

One ore more packet, each prefixed with their varuint-encoded length, compressed with zlib's deflate algorithm.

Fields:

• data

  Compressed data.

  Pseudo-code for decompression:

  							ubyte[] uncompressed = uncompress(batch.payload);
  int index = 0;
  while(index < uncompressed.length) {
     int length = varuint.decode(uncompressed, &index);
     if(length < uncompressed.length - index) {}
        ubyte[] packet = uncompressed[0..length];
        index += length;
     }
  }
  
  						

  Pseudo-code for compression:

  							ubyte[] payload;
  foreach(ubyte[] packet ; packets) {
     payload.concat(varuint.encode(packet.length));
     payload.concat(packet);
  }
  Batch batch = new Batch(compress(payload, Zlib.DEFLATE));
