json format can be given by \_BULK API [1.To](http://1.To) index into ES is there any other way or format(not json) which is read by elasticsearch 2.Also i dont require logstash as it can send csv format. Only elastic search and its accepting format types.. please reply,.. ---

Elasticsearch only supports JSON. If you want to send something else you need to transform it. You can use logstash or whatever other system (even your code). ---

thank you. when does elastic search perform best (in context of performance testing) 1. with indexing data format in JSON (or) 2. with indexing data format in CSV ---

It does not make sense. As I said you can only send json docs to Elasticsearch. Note that in Kibana 5, you'll be able to upload CSV directly from the interface. ---

There is a caveat. Elasticsearch can support different encodings for that _JSON_. Namely you can read/write/store data in several [json-like formats](https://github.com/elastic/elasticsearch/blob/2.4/core/src/main/java/org/elasticsearch/common/xcontent/XContentFactory.java#L104). That would be: - JSON itself - YAML - Smile - has better serialization performance than json, but can be larger than JSON if storing many small numbers. - CBOR - much better performance than json. variable size number encoding which saves space. But unfortunately there is no [bulk support](https://github.com/elastic/elasticsearch/issues/8481) for CBOR format. In order to utilize these formats you have to talk to ES via native driver and not JSON interface. So yes, if you're looking to squeeze a little extra out of the server I would advise using _Smile_ until _CBOR_ support is complete. ---
