For historical reasons, the handling of FOREIGN KEY constraints in MariaDB Server is somewhat peculiar. Unlike CHECK constraints, which are being enforced at the query execution layer for all tables, FOREIGN KEY constraint definitions will simply be ignored unless the underlying storage engine supports them.
The storage engine is not only responsible for enforcing referential integrity between tables, but also storing the constraint definitions. Currently, InnoDB is the only storage engine that supports foreign key constraints, between persistent, non-partitioned tables.
Partitioning is implemented by a storage engine wrapper that makes each partition or subpartition appear as a separate table in the underlying storage engine.

At some point, nearly every developer encounters a common challenge: working with deeply nested JSON only to run into an arbitrary depth limit imposed by the database.

To address this, we decided to remove the limitation entirely.
The database now supports JSON documents and JSON paths with virtually unlimited nesting! This change unlocks the ability to work with more flexible and expressive data models without forcing developers to restructure or flatten their data.

One of the standout features of Oracle PL/SQL is the associative array — a versatile and efficient in-memory data structure that developers rely on for fast temporary lookups, streamlined batch processing, and dynamic report generation.
With the MariaDB 12.1 preview release, we’re excited to announce that associative arrays have landed in MariaDB as part of our growing set of Oracle compatibility features. This milestone, tracked under MDEV-34319, brings Oracle-style associative arrays into the MariaDB procedural language — complete with native type declarations, variable construction, and method support.
Let’s explore what’s included, what’s different, and how this feature was implemented from the ground up.
