Ably Pub/Sub has introduced a cost optimization feature called server-side message batching to address the challenges of high-scale, high-frequency messaging and burst activity. This feature reduces the number of messages sent over the network, optimizing bandwidth usage and lowering costs. By combining multiple messages into batches, developers can focus on application development instead of working through the mechanics of batching. The feature offers predictable cost reductions and latency, allowing users to customize the batching interval to suit their specific needs. It is particularly beneficial for high-volume chat applications, fan engagement platforms, virtual events, and collaboration tools that experience spikes in message volumes during high-impact events or user concurrency. With simple configuration through the Ably dashboard, developers can start batching messages quickly and easily, without extra development work or cognitive load.
