Remove invoker caching from Workflow interpreter
------------------------------------------------
Key: AIRAVATA-252
URL: https://issues.apache.org/jira/browse/AIRAVATA-252
Project: Airavata
Issue Type: Improvement
Reporter: Chathura Herath
Fix For: 0.3-INCUBATING
Currently in XBaya workflow interpreter we cache the invokers. THis was done so
that if the user reruns the workflow we could reuse the invoker as well as we
could simply use it as the service output store.
Two issues with this are;
1)If the invoker is cached and at a later time reused if the time between reuse
is more than proxy expire time, it will fail and reuse cannot be made anyway
2) Statistically cases that will reuse the invoker is much less than cases that
it will use once. So this performance gain can be let go of a memory gain. If
the user is rerunning, user is in the execution cycle and performance gain will
anyway go unnoticed
So i propose to remove the invoker map and store the output in the workflow
node itself in the graph as possible Futures object.
