How can I perform compression in Elasticsearch ?  
I tried best\_compression but not good at all and also disabled some fields. Wherease Splunk stores index data equal a half of raw data, Elasticsearch stores index data bigger than raw data almost case. Thanks

When evaluating storage size, have you done the following:

- Optimized your mappings according to [these guidelines](https://www.elastic.co/guide/en/elasticsearch/reference/6.2/tune-for-disk-usage.html#tune-for-disk-usage) and [this blog post](https://www.elastic.co/blog/filebeat-modiles-access-logs-and-elasticsearch-storage-requirements).
- Ensured that you have large shards (\> 1 GB) to ensure compression is efficient.
- Run [force merge](https://www.elastic.co/guide/en/elasticsearch/reference/6.2/indices-forcemerge.html) on the index with `max_num_segments` set to `1`.
- Looked at how much data you are adding in form of enrichment
