Hi Perplumblewintz, While technically you could try to customize segment size using a custom MessageBuilder subclass, I don't think it's going to work very well for such tight constraints. Instead, I'd suggest you serialize the whole message into a byte buffer upfront, apply any compression (whether that be packed mode or a real compression algorithm like zstd), then split the final buffer into 100-byte chunks. Then reassemble on the other side before parsing.
