Hi... I am working with last 6 months of data. I am going to push my data into elasticsearch by using logstash. The 6 months of data divide into sub folders by referring date. As example data related in 2017-07-17 will containing folder call 20170717. I want to know best procedure to generate indexes for this large number of data set. Thank you

Logstash will do this by default, see [https://www.elastic.co/guide/en/logstash/current/plugins-outputs-elasticsearch.html#plugins-outputs-elasticsearch-index](https://www.elastic.co/guide/en/logstash/current/plugins-outputs-elasticsearch.html#plugins-outputs-elasticsearch-index)
