Subject C++ messaging client: fractional values for reconnect parameters?
Date Wed, 01 Feb 2012 15:21:22 GMT
Presently the C++ client takes options for reconnecting (reconnect-timeout, 
reconnect-interval-min/max etc.) in seconds. A second is too long for 
applications that require rapid fail-over. I'd like to make these values more 
fine grained, but I don't want to break the existing interface.

Proposal: Have C++ treat reconnect time values as floats, so e.g. 
reconnect-interval-min=0.001 sets a millisecond as the minimum interval. 
Existing code will be unaffected. I believe this is already the case for the 
python client, since python normally expresses time in floating-point seconds.

Does anyone see a problem with this approach or have an alternative suggestion? 
The only alternatives I can think of are:

- break backward compatibility and re-interpret reconnect values as milliseconds 
or nanoseconds rather than seconds.
- add another set of reconnect-timeout-ms or reconnect-timeout-ns options on top 
of the existing second options.

I don't like either of those.
