All those views are in the same pickle object, and so shouldn't be duplicated. That is frustrating.

As per @shoyer, the easiest way is to just not have the data in the first place. So not needing indexes at all should solve your case.

When pickling something with a reference, do you want to save the object, or the reference? If you pickle the reference, how can you guarantee to have the object available when unpickling? How would you codify the reference (memory location?)? 

Is that right? Or am I misunderstanding your problem?

On this narrow case, I think not having indexes at all should solve this, though
