             Summary: Improve calls to the localStorage
                 Key: AMBARI-12868
                 URL: https://issues.apache.org/jira/browse/AMBARI-12868
             Project: Ambari
          Issue Type: Bug
          Components: ambari-web
    Affects Versions: 2.1.1
            Reporter: Oleg Nechiporenko
            Assignee: Oleg Nechiporenko
             Fix For: 2.1.2


methods like {{setDBProperty}} and {{getDBProperty}} work slow, if are used several times one after another. Example:
{code:javascript}
var a = this.getDBProperty('a');
var b = this.getDBProperty('b');
var c = this.getDBProperty('c');
{code}
Each getDBProperty-call does {{localStorage.getObject}} which may be slow if readable object is too big (it may take 100-150 ms). So, it's better to read list of values with one call, like:
{code:javascript}
this.getDBProperties(['a', 'b', 'c']);
{code}
And same for {{setDBProperties}}.
