Difference between ignore_older and sincedb_path in logstash
<p>I'm gathering data from csv file. since data should be imported only one times, I needed to set some config for it in logstash.
Below both config works same way that brings only new added rows. Any difference between them?</p>

<pre><code>1.
start_position =&gt; "beginning"
ignore_older =&gt; 0 

2.
sincedb_path =&gt; "/dev/null"
start_position =&gt; "end"
</code></pre>
