Re: [rules-users] Running rules from the past
@Ansgar, it looks like you are doing in a database the work that it's
being done by Guvnor, that keeps a lot of meta data for all the
snapshots and it's ready to keep the snapshots forever, exposing them
via a service, so you applications can get the right version. In the
same way that you mention just knowing the ID of the snapshot that
it's required.
Using Guvnor, there is no need to remove snapshots, each snapshot will
only contain the rules associated with it and not a complete
application.

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
