The short version

  • Each has a real cost: Crossplane requires Kubernetes expertise and infrastructure; MariaDB jSON support using text fields rather than native binary type; lacks MySQL's JSON syntax and functions
  • They diverge on capability: Crossplane covers Kubernetes extension, MariaDB covers MySQL Compatibility.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Crossplane

  • Requires Kubernetes expertise and infrastructure
  • Steep learning curve for teams new to Kubernetes patterns
  • Provider ecosystem smaller than Terraform

MariaDB

  • JSON support using text fields rather than native binary type; lacks MySQL's JSON syntax and functions
  • Galera Cluster maximum performance limited to the slowest node in cluster
  • InnoDB tables limited to 1,017 columns and 64 secondary indexes
  • Transaction size limits in Galera (128K rows and 2GB by default)
  • Less strict SQL type checking than PostgreSQL; allows implicit conversions

Answered from the vendors’ own pages

Crossplane: Is Crossplane free?

Yes, Crossplane is open source and free to use. It requires a Kubernetes cluster but has no licensing costs.

Source
MariaDB: Is MariaDB completely free and open source?

Yes. MariaDB Server is licensed under GPLv2 and guaranteed to remain perpetually free and open source, independent of any commercial entities.

Source
Crossplane: What is Crossplane used for?

Crossplane is used to build control planes and platforms for infrastructure management, enabling platform teams to expose safe APIs to other teams.

Source
MariaDB: Is MariaDB backward compatible with MySQL?

Yes. MariaDB was designed as a drop-in replacement for MySQL. Every application, driver, and configuration that worked with MySQL works with MariaDB without code changes.

Source
MariaDB: What are the storage engine options in MariaDB?

MariaDB supports multiple storage engines including InnoDB (transactional, default), Aria (crash-safe, good for read-heavy workloads), and MyISAM. The Aria engine is faster than InnoDB for certain read-heavy queries and full table scans.

Source
MariaDB: How much does MariaDB cost?

MariaDB Community Server is completely free to download and use. MariaDB offers paid enterprise support and managed cloud services for organizations needing professional support.

Source
MariaDB: Does MariaDB support native JSON storage?

MariaDB stores JSON using text fields (the JSON type is an alias for LONGTEXT), not as a native binary type like MySQL does. JSON support exists but is less sophisticated than MySQL's JSON functions and syntax.

Source
MariaDB: What scaling options does MariaDB provide?

MariaDB supports both scaling up (more cores, memory, storage) and scaling out (read replication, Galera Cluster with multi-node replication). However, Galera Cluster performance cannot exceed the slowest node in the cluster.
