Message Delta Compression: Bandwidth-efficient realtime messaging

Message Delta Compression reduces the bandwidth required to transmit realtime messages by sending only the changes from the previous message to subscribers each time there’s an update, instead of the entire message. Let’s say the first message sent over a channel is 16KiB and the message after that is the same but with an additional 4KiB of new data. With Delta Compression that message will have a payload of only 4KiB instead of 20KiB. This reduces bandwidth costs, improves latencies for end-users, and simplifies development by taking care of message size optimization. read on... here: https://www.ably.io/blog/message-delta-compression/
