Re: [rules-users] Running rules from the past

Did you try Guvnor? it already store the snapshots version. So you can
get the right snapshot for running your rules against an old Loan
again.
@Ansgar: why do you recommend to not use snapshots?
They change over time, making it more complex to track down the correct
version.
I'd preferr a stable loan application <=> rule set association. OTOH, it is
probably *possible* to retrieve the correct snapshot version for a loan
application if additional metadata is available. It's just more
complicated: metadata needs to be available and sufficient to determine
exactly *one* snapshot, snapshot needs to be available (not sure if Guvnor
stores all snapshots forever or just a few).
For releases, there is *one* figure you need to know to reference a certain
ruleset (the version number). Releases are normally kept forever. Or, at
least in my environment, deleting releases is done with extra extra care
-if at all-, whereas snapshots older than a week or so get removed
automatically on a daily basis.
Best regards,
Ansgar
