Space requirements

(Srividya Srungaram) #1

Is there any calculator for disk space requirement for ES? For example for each k number of docs with n number of fields we ll need x GB. Can you give an example?
Also how do we specify the retention policy for the documents?

No, there is not, as it depends on a number of factors. Best way is to find out is to index a sample of your data and see. make sure that you index a good amount of data (at least a few tens of MB) as compression generally improves with shard size.

For managing retention, I would recommend you look into Curator.
