sparse indexes for Pheonix

Curious, has anyone looked at implementing sparse Indexes in Phoenix?
It seems like it would be a natural fit for secondary indexes that are too
large to fit in memory naturally.

I'm thinking of something like Postgres BRIN indexes

Not sure if the block layout on disk, or the underlying HBase
implementation would even allow this.

Asking here before I pursue it more.

Thanks,
