Re: [xmlblaster] Queue and starving

[Michele Laghi <laghi at swissinfo.org>]

Ciao Michele,
in fact there is no mechanism to avoid such "starving" of low priority 
messages. I believe it is a correct behaviour to priorize high priority 
messages. If there are no free resources available to sent all messages, 
then it is correct to hold back low priority messages.

Of course you could discuss the fact that messages which are in the 
queue since a long time become a higher priority but this is a specific 
behaviour (you could have other such behaviours) which could be solved 
with a specific plugin.

Cheers
Michele (Laghi)
