We are using ES on AWS EC2 instances and we are want to reduce our JVM usage. The most common solution to this is to use doc values and thus reducing the in memory field data. When we tried it on a test system this is resulted with high I/O consumption and very large storage.
We want to use the doc values in the ephemeral storage but when I looked into it the doc values files are stored with the all the other data.
Is it possible to make a way to store the doc values only on another filesystem?
Thanks in advance,
