Subject Re: Architecture discussion about monitor and gfac integration
Date Mon, 21 Apr 2014 00:08:46 GMT
Hi All,

I think after the discussion following things were concerned.

GFAC execution chain is broken and all the executions became asynchronous.

GFAC monitoring abstraction is not required in all the cases and when
someone try to extend the gfac they have to extend the monitoring and
provider interface.

I think we will be able to solve the above concerns by supporting gfac
execution chain for old synchronous mode and this will let developers to
extend the provider functionality without using monitoring abstraction we
have currently. If they prefer to execute the chain in asynchronous mode
its up to them to extend the monitoring abstraction or resuse existing
monitoring implementation.

I will implement the above solution and arrange another review session.
Thank You everyone for the inputs during the discussion.

Regards
Lahiru
