Hi everyone,
I started learning about Elasticsearch last week and I found it great.
I noticed that by default Logstash ( yes we want to use elastic for storing logs, but I guess we will go further than storing logs) names indexes as myindex_yyyy.mm.dd.
What is the purpose of this approach, what is the benefit ?
I found that we can easily search by indexes like myindex__* or myindex_2015.*.
So, my main question is: why is that set by default, do I have to do the same? What will be different if I name index just myindex without date ?
Best, Ihor.
