MariaDB Support Services

MariaDB Corporation delivers technical support services including Problem Resolution Support, Engineering Support, and Consultative Support for MariaDB Enterprise, MySQL Server, and related products via its web- and email-based Customer Support Center (CSC). All support services are delivered in English.

Each designated technical contact will receive a CSP login (based on the associated email address) that can be used to report new support issues, monitor ongoing issues, or review historical issues. Information regarding making changes to technical contacts can be found in the "Welcome Kit" provided after signup, and is also available in the Help section of the CSP.

Problem Resolution Support

The focus of Problem Resolution Support is helping to restore service (due to outages caused by crashes, replication failures, table corruption, etc.), and assisting with command syntax, installation, configuration, upgrades, and other general product usage topics.

Engineering Support

Engineering Support involves bug fixes, patches, hot fixes, and topics that require communication with the product engineering team. Custom Feature Development (Non-Recurring Engineering) is a separate service and is not included in Engineering Support.

Hot fixes are provided to address critical failures and may not receive the full QA and regression testing performed on regular maintenance releases due to the urgent nature of the situation.

Consultative Support

Consultative Support covers issues that are specific to a customer’s deployment, such as performance tuning, best practice recommendations, and code reviews, rather than general product usage, service failures, or software defects. MariaDB Remote DBA is a separate service and is not included in Consultative Support.

It is intended for narrow, specific topics and is not a replacement for a dedicated, on-site consulting engagement to address systemic, architectural, or wide-ranging subjects.

Consultative support is only available to MariaDB Enterprise Advanced and MariaDB Enterprise Cluster customers.

Performance Tuning

MariaDB Support Engineers will provide assistance resolving performance problems caused by server configuration, "bad" queries, table definitions, indexing strategies, storage engines, and more, suggesting changes and identifying alternative implementations suited to a particular environment.

Code Review

MariaDB Support Engineers can review source code to assist with following best practices and ensuring code correctness regarding the various client APIs, stored SQL and server extensions, recommending changes as necessary to support particular needs.

Login Support

MariaDB Support Engineers may log in to customer systems, subject to customer request and approval, to gather diagnostic information or attempt a problem resolution directly.

Login support is intended for exceptional circumstances when diagnosing or resolving a technical support problem requires direct access to the system. It should not be used for routine technical support issues.

Customers must provide remote access to the system, which may involve opening ports on the network firewall. Unix-based systems can provide access via the secure shell (sshd) service, while Microsoft Windows Server systems can provide access via Terminal Services. Customers may also be able to provide access via “shared desktops” using Webex, Dimdim and similar web conferencing systems.

MariaDB Support is unable to assist in configuring customer systems and networks to provide remote access for login support.

Issue Severity

All support issues are assigned a Severity level reflecting the impact to production operations. This is set initially by the technical contact when reporting a new issue via the CSP, and MariaDB Support will help to ensure that the issue receives an appropriate rating:

  • Severity 1 (S1): Catastrophic problem that severely impacts the ability to conduct business. This means that production systems are down (completely non-responsive or not functioning) and no known workaround exists.
  • Severity 2 (S2): High impact problem in which production operations are disrupted but remain somewhat productive or have an available workaround.
  • Severity 3 (S3): Medium or lower impact problem that involves partial loss of non-critical functionality. This may be a minor issue with limited or no loss of functionality or impact to production operations. This includes administrative requests and errors in product documentation.
  • Severity 4 (S4): Low level problem that does not significantly affect system function or operations. This includes new feature requests.

In exceptional situations, MariaDB Support may elect to assign an S1 or S2 Severity level for failures on non-production systems based on the overall business impact.

Telephone Support

For S1 emergency production outages, customers may request that a MariaDB Support Engineer make contact by telephone. Resolving technical support issues generally requires analysis of system logs and other data that must be transmitted via email and file attachments to the support issue rather than by telephone. Including this information when reporting the support issue dramatically hastens the process of resolving the problem and restoring production functionality.

Escalation Requests

Customers may request escalation of a specific support issue directly within the CSP by clicking the Escalate Issue link at the top of any issue details page, then selecting the type of escalation and supplying other relevant information.

Available escalations include:

  • Emergency Callbacks for S1 emergency production outages
  • Higher Priority Handling when an issue has become more serious than reported
  • Engineer in Different Timezone
