------------------------------------------
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}}.
