Batch.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));
