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 https://www.percona.com/blog/2019/07/16/brin-index-for-postgresql-dont-forget-the-benefits/ 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, Ben DeMott
