Hi,
i m trying to undestand how does parallelism works in ES ...
Searched around and read several itens about it but cant find the right answer to my question.
I find myself , probably, missing some concept or confiuration...
She scenario is straight forward - ES with LogStash working to read around 20 files from several IIS installed in my infra-structure.
It works well and it load all information into ES.
Since those files are gigs in size, it takes a while loading all info into ES. But when i refresh the graphics showing, for example, total hits, it slowing builds one graph at a time. I m hitting the refresh button and i see the info in one graph increasing , and only after it ends, it goes to the next graph. Like its loading info in sequential order.
I was expcting to see several graphs showing new date at the same time and not one at a time.
Used pipeline with multiple workers ,but didnt change the beahviour and tryed the -w option in logstash and had no effect also.
Now i m confused beetween read parallelism and bulk paralllelism ... 
What am i missing here.... ?
( Windows 2012 with ES 7.4 with LS 7.4 also )
Thks in advance.
