As we know elasticsearch stores the logstash indices in the format logstash-yyyy.mm.dd. Does elastic search creates new indexes for new date by re-indexing previous day indexes?
Ex: I am observing every day logstash-* folders content in getting increased by twice the previous day size.
logstash-2015.11.17 was ~500MB,
logstash-2015.11.18 was ~1.5 GB and
logstash-2015.11.19 is > 3 GB
