I have an elasticsearch-1.7 cluster and ingest about 800GB log data into an index. Then I found the `/_cat/indices` API show me the index size was 2.2TB. The `number_of_replicas` of this index has already been set to 0. The `_all` field set to be `disable` too. So, how could the index size inflate so much ?! Nearly 3 times. Most of the log data haven't extract new fields. They only have some meta field and one raw message. only 10% of the data was JSON format that may have some fields. * * * I had heard some information that elasticsearch-1.x may use more space after segments merge if multiple \_type have some field but typeA has a little doc with long length and typeB has lots of doc with small length. Is this possible problem keeping the same in only one \_type in one index? Is this resolved in elasticsearch-2.3? ---

What's the mapping look like? ---
