Abstract:
A system includes one or more application nodes sending SQL queries to one or more query execution nodes. Each query execution node translates the SQL queries into key-based requests to the storage engine, which comprises one or more storage nodes. The system provides an abstraction layer with an external schema and an internal schema, maps the external schema into the internal schema; and generates one or more microshards for the storage node.
