bfetch.It is especially beneficial to applications that send multiple requests in a session, like
dashboard.It should address customer complaints on loading taking long and using a lot of network due to making multiple connections.
Without
bfetchWith
bfetch, the dashboard is re-loaded using a single request.Edge cases and things to pay attention to
Requests can be sent in more than one batch. Batches are limited by size and by time. In some cases, multiple batches might be sent

bfetchstream is hung up for some reason, all requests are rejected properly.Release Notes
