Document database backed by keyvalue storage P&L: 0 (≃ 0 CNY)
I am interested in database technology and distributed systems.
I have an experimental python project which is less than 1000 lines and supports basic SQL and SQL inner joins and basic Cypher graph database queries and keyvalue storage. There is no persistence layer.
On the linked website page from this project which is GitHub issues I am talking how I plan to implement document storage so that JSON documents can be mapped to individual keys and joined with SQL queries.
