Major Description
The goal is to minimize the number of connections from the client to the brokers.
On the Java client, there are potentially two types of network connections to brokers:
- Connections for metadata requests
- Connections for fetch, produce, etc. requests
The idea is to apply a much shorter idle time to client connections that have only served metadata (type 1 above) so that they become candidates for expiration more quickly.
Alternatively (or additionally), a change to the way metadata requests are routed could be made to reduce the number of connections.
