Make JSON DEPTH unlimited – new feature in MariaDB 12.1

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. In our case, that hard cap was set at 32 levels — sufficient for many scenarios but too restrictive for more complex or dynamic data structures. 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.

Bringing Oracle’s Associative Arrays to MariaDB

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.
