Joseph Wu commented on MESOS-9258:
----------------------------------
Still in progress, but a prototype is up for preliminary review starting here:
https://reviews.apache.org/r/69180/
The idea is to let the {{master /api/v1 SUBSCRIBE}} call take a streaming
request (optional) as well as a streaming response. When the call is made via
a streaming request, the same stream will be used to send heartbeats from
client to master.
> Consider making Mesos subscribers send heartbeats

> Key: MESOS-9258
> URL: https://issues.apache.org/jira/browse/MESOS-9258
> Project: Mesos
> Issue Type: Improvement
> Components: HTTP API
> Reporter: Gastón Kleiman
> Assignee: Joseph Wu
> Priority: Critical
> Labels: mesosphere
>
> Some reverse proxies (e.g., ELB using an HTTP listener) won't close the
> upstream connection to Mesos when they detect that their client is
> disconnected.
> This can make Mesos leak subscribers, which generates unnecessary
> authorization requests and affects performance.
> We should evaluate methods (e.g., heartbeats) to enable Mesos to detect that
> a subscriber is gone, even if the TCP connection is still open.
