Hello, I'm building a site (a "dictionary") using couchdb, es and the couchdb river plugin. The database contains around 40000 words and short definitions. I would now like to host this on a VPS and my question is: What are the memory (ram) requirements (how can I estimate?), is there a way to experiment with this on my dev box (it has 4gb and am just using the standard out-of-the-box settings)? Does "top" provide a good estimate? --Albin ---

By default, ES\_MAX\_MEM is set to 1gb. For such a small index, you can certainly go with less. The way to test it is to simply index the data, run some searches, and check that things are ok memory wise.

Hi, If i try to index of 1 lac docs (including searches) then how much would be of my RAM size? -jagmee On Feb 20, 6:15 am, Shay Banon [shay.ba...@elasticsearch.com](mailto:shay.ba...@elasticsearch.com) wrote: > By default, ES\_MAX\_MEM is set to 1gb.

Can't answer that, as it varies greatly depending on many factors, including type of searches, sorting, facets, number of terms the index ends up with. You need to test it, and see. The node stats api can give a lot of info when it comes ot memory allocations.
