Subject [jira] [Commented] (FALCON-1108) Custom recipe processing
Date Sat, 21 Mar 2015 10:06:38 GMT

Srikanth Sundarrajan commented on FALCON-1108:
----------------------------------------------

[~ajayyadava] Yes I was talking about isolation between different recipes. We need to be particularly
concerned about the isolation for the following things

* Class Path (libraries & dependencies) - different recipes may choose their implementation
with conflicting libraries
* Memory isolation (to protect against memory consumption & leaks of any one specific
implementation)
* Other resources (cpu/network)

Essentially we need make sure that one specific recipe isn't hurting the availability of the
service as a whole and doesn't cause issues for other recipes.

To provide for this level of isolation from within a single JVM might be complex and such
complexity is avoidable.
