Hi, I have a doubt over number of fields in Elastic. Since elastic keeps a default limit of 1000, can I ensure that less than 1000 fields will definitely not lead to a mapping explosion? Also, is there a certain number which can ensure me of Mapping Explosion? What are the most obvious causes of Mapping Explosion ? ---

Is this not a duplicate of [this thread](https://discuss.elastic.co/t/elastic-mapping-explosion/162647/10)? Please do not open multiple threads around the same question. ---
