Make Reconnect Failure Behavior Configurable #622

Open pglombardo opened 4 months ago

pglombardo commented 4 months ago

🚀 Feature Request

Currently, when using automaticReconnectWithDefaultConfig, the client may hang indefinitely if it can't reconnect to the broker.

As pointed out (and requested by @dowhiletrue in #302), users would like the ability to configure this behavior to either:

There are three options on top of my mind:

  • block
  • throw
  • continue and try to connect later

Which option fits best depends on the use-case. Make the behavior configurable?

🔈 Motivation

🛰 Alternatives

For the existing behaviour, a work-around was provided by @SgtSilvio here.
