Subject Aw: Re: nifi 1.4 - variables

<html><head></head><body><div style="font-family: Verdana;font-size:

<div>thank you Bryan.</div>

<div>&nbsp;</div>

<div>is there documentation around for the variables?</div>

<div>&nbsp;</div>

<div>If I add variables to the processor group and I want to reference a variable of
the parent flow, will I have to add the scope somehow like &#36;{scope.variable}?</div>

<div>
<div>&nbsp;</div>

<div>If I have variables in different hierarchies of the flow with the same name, which
one will be used?</div>

<div>&nbsp;</div>

<div>&nbsp;</div>

<div>P.S. I really like your blog :-)</div>

<div>&nbsp;</div>

<div>Rgds,</div>

<div>&nbsp;</div>

<div>Uwe</div>

<div name="quoted-content">Hello,<br/>
<br/>
You can use them in any fields that support expression language, just<br/>
like variables in a properties file<br/>
(nifi.variable.registry.properties= in nifi.properties) or system<br/>
properties in bootstrap.conf.<br/>
<br/>
In the properties file approach you had to restart NiFi for any<br/>
changes in the properties to be picked up.<br/>
<br/>
In the new approach you no longer need to restart anything yourself,<br/>
it will be handled for you.<br/>

&gt; Hello,<br/>
&gt;<br/>
&gt; in 1.4 when you right-click the processor group then there is an entry<br/>
&gt; &quot;variables&quot;. I have defined some, but I wonder how I can use them.<br/>
&gt;<br/>
&gt; I have not found documentation on this. Does somebody have details or a<br/>
&gt; link to documentation or an example?<br/>
