Is there a matrix out there with the various needs that one might have of a DB/storage solution (consistency, throughput, sharding, replication, etc) with products associated with each of those sets of requirements? I feel like for a lot of what I do on a daily basis I do end up using the same old one-size-fits-all approaches, and as those scale we feel the pain -- but the product search and vetting process is tough and time consuming to even begin. Would be nice to be able to narrow options down to a smaller search space at least.
