Alternatively, Google Spanner is a horizontally-scalable SQL database, built for massively scalable and geo-distributed applications. Our plan was to first move the PostgreSQL system tables into DocDB (the storage layer of YugaByte DB) with support for some a few data types and some simple queries initially, and add more data types and query support over time. Our post Distributed PostgreSQL on a Google Spanner Architecture – Query Layer highlights how the query layer works in detail.
