I am kind of new in the ES word, i work with ES V5 and I have some questions...
Thanks in advance to lightening me
I need to know the total real occupancy of my datas through my ES cluster.
To do that, I use those commands : _cat/shard and _cat/indices
A very simple and short document (only one field, just a letter as a value...) takes 7kb while this document weighs barely 500b...
I am half surprised : in a way, I understand that this document will be stored and/or indexed and then, it cost more than the original payload. But, normally, with compression, I was expecting a little bit more efficient...
-So, first question : is it "normal" to observe that thing ?
-Is the use of _cat/shards and _cat/indices give the true size (uncompressed) of datas or the compressed size of datas ?
-If a "Double" value costs 64bits (8octets), how many cost a "Text" (String) value ?
-Will a property name in a document ("property_name":"value") will cost like a "Text" value ?
Again, thanks a lot
