Cleo needs lot of memory -- using SSD instead of memory

[Vadi]

We have been using Cleo in production for an year now. It works flawlessly. We are indexing 9m documents that needs hefty amount of memory.

In the world of SSD, is there a way I can use some kind of DiskStore to keep elements instead of memory. I am not sure how to make this happen. Any help would be greatly appreciated.
