70-80% of the storage use for my indices are the Stored Fields. - that is, the .fdt files.
I am running in the cloud, and this becomes expensive, since I need quite large machines to contain the indices.
The total size of the indices are ~15-20TB.
Therefore I think about moving the stored fields onto a cheaper disk. I am aware, that this will make queries slower, but is it possible to do in an elegant and easy way?
Ie. by setting a pointer to the .fdt files position, somewhere in the settings?
I am running es 1.7.5, and I am aware that it would be preferable to upgrade it, but it is currently not a possibility
What I am looking for, is probably elastics implementation of this lucene feature:
