...Written fully in C++: starts fast, doesn't take much RAM, and low-level optimizations provide good performance. Can sync from MySQL/PostgreSQL/ODBC/xml/csv out of the box. Not fully ACID-compliant, but supports transactions and binlog for safe writes.
...Apart from multithreading it offers such features as multi-master replication, persistence capabilities, horizontal and vertical scalability and direct backup to AWS S3 right out of the box. KeyDB remains fully compatible with Redis protocol, modules, and scripts, including the atomicity guarantees for scripts and transactions. Keeping in sync with Redis development, it is a superb drop in replacement for existing Redis deployments.
RAQUEL : "Relational Algebra Query, Update and Executive Language"
...As a language, RAQUEL is to :
1. be a pure relational algebra language (unlike SQL) as defined by Date & Darwen's "The Third Manifesto";
2. incorporate a generalised extension of the ANSI-SPARC 3-layer DB architecture;
3. have the maximum ratio of functionality to conceptual complexity (as defined by Fred Brooks).
As a DBMS, RAQUEL is to :
1. have an Open Architecture, enabling a variety of DBMS configurations of 'black box' code, each installation optimised for a certain kind of DB;
2. be a stack of core black boxes to provide general DBMS functionality, plus a range of plug-in black boxes to support different physical storage mechanisms & scalar data types;
3. employ code designed with a mixture of functional, OO & other methods so as to minimise internal DBMS state complexity.
