Subject: Use keys to speed DB queries
X-Git-Tag: 3.0.2-ONAP~10^2
X-Git-Url: https://gerrit.onap.org/r/gitweb?a=commitdiff_plain;h=refs%2Fchanges%2F36%2F85336%2F1;p=policy%2Fmodels.git

Use keys to speed DB queries

When a filter specifies a name (and possibly version), those can
be used to speed DB searches.  Modified the code to use the keys
rather than always retrieving every record before applying the
filter.
