What is the relationship between SingleStore DB and MySQL?

SingleStore DB is a standalone distributed database that is compatible with MySQL client software.

SingleStore DB is not a storage engine or other component of MySQL, nor is MySQL a component of SingleStore DB, and the SingleStore DB and MySQL servers do not share any code. The SingleStore DB server includes its own storage engine and SQL-based execution engine built around scalable distributed execution, lock-free data structures, and machine code generation.

Users use MySQL client software to connect to the SingleStore DB server. SingleStore DB uses the same wire protocol as MySQL and supports similar SQL syntax as MySQL for compatibility with MySQL client software.
