PostgreSQL/MySQL - Any-to-Any Database Wrapper
Similar to the gaming concepts of, I believe, Vulkan, Wine and Cedega, we could abstract out databases not on an ORM level, but on the DBMS protocol level.
Often, organisations support one database management system (DBMS), a relational DBMS such as PostgreSQL, MySQL or other proprietary DBMS, which I am reluctant to mention.
What if we could write a middleware that would act as a server of any DBMS protocol? That middleware could then replace the DBMS in question with a thin O(1) layer and just use the one the organisation wants. O(1) because prepared statements would be cached and in a hashmap that could provide O(1) added latency that could be sub-milliseconds and would not contribute to the bulk of the cost of the query.
This middleware could be written in any language as it would add only O(1) overhead to any DB queries posed by the client. This seems to work quite well for even games that have sub-ms queries and still run with near-native performance.
It would depend on the languages and libraries that they have. Maybe MariaDB and PostgreSQL have some code that could be re-used.
The prepared statements of queries could be cached in an efficient DB table that itself could work on any DBMS or just PostgreSQL for example.
It might be easiest to write it as a PostgreSQL extension that runs on a port and provides the MySQL API.
I think for now I would only use Regular Expressions, but later something like ANTLR might be the way to go.
OK, enough talk … I think I might actually start trying this out in a proof-of-concept for a small subset of queries.
One of my problems: Too many ideas and too little time. :-)
