The short version

  • Each has a real cost: Consul namespaces, admin partitions and other multi tenancy controls are Consul Enterprise only; MariaDB jSON support using text fields rather than native binary type; lacks MySQL's JSON syntax and functions
  • They diverge on capability: Consul covers Service discovery, 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.

Consul

  • Namespaces, admin partitions and other multi tenancy controls are Consul Enterprise only
  • Audit logging, OIDC authentication and FIPS 140-2 builds require Consul Enterprise, so compliance driven deployments cannot use the free edition
  • Automated backups, redundancy zones, read replicas and automated server upgrades are Enterprise only
  • Long Term Support releases are Enterprise only, so community users must upgrade to stay supported
  • Service mesh and advanced traffic management sit in the Premium Enterprise tier above Standard Enterprise
  • HashiCorp does not publish a Consul rate on its pricing page, which lists per resource prices for Terraform instead

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

Consul: How much does Consul cost?

Consul does not publish specific pricing. The open source Community edition is free. HashiCorp also offers a Consul Enterprise edition, but pricing details are not disclosed publicly and must be obtained by contacting HashiCorp sales.

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.

Consul includes a free, open source Community edition. HashiCorp also offers a proprietary Enterprise edition for organizations requiring advanced features, but no public pricing is available for the Enterprise version.

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 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.
