Greetings, I have found plenty of documents on guiding configuration tuning and plenty of use cases showing performance for a particular collection, but is there any advice which provides a reasonable hard number estimate based upon collection size ? (i.e. number of documents, total disk size of documents...) We plan to have 4 million documents with around a terrabyte of storage in raw json format. Thanks for any pointers.....love this product, it is fantastic....although it is still early in our relationship.

No, because there are still a number of variables that factor into this to make it into another "it depends". Things like heap, CPU, disk, query types, ES version, cluster and index size and setup, On 31 January 2015 at 04:39, Tony Neil [captaintneil@gmail.com](mailto:captaintneil@gmail.com) wrote: > Greetings, > > I have found plenty of documents on guiding configuration tuning and > plenty of use cases showing performance for a particular collection, but is > there any > advice which provides a reasonable hard number estimate based upon > collection size ?

You can get poor performance with 1TB of data if: - Your queries are not right (e.g. not using right filters/using wrong ranges etc) - Inferior storage hardware - Insufficient memory (RAM) You can get really great performance on the same data set of 1TB - if you have SSDs - enough RAM to cache the data - right cluster topology (e.g. dedicated data/client/master nodes) So the answer depends on how a lot of factors. 🙂 On Friday, 30 January 2015 09:39:11 UTC-8, Tony Neil wrote: > Greetings, > > I have found plenty of documents on guiding configuration tuning and > plenty of use cases showing performance for a particular collection, but is > there any > advice which provides a reasonable hard number estimate based upon > collection size ?
