MariaDB Support

24/7 MariaDB Support with a 15-Minute Emergency SLA

Last reviewed by Scott Sternloff

AceMQ provides MariaDB support for production estates: Galera nodes that will not rejoin after an SST, a cluster that dropped to non-Primary during a network partition, replicas that lag through the nightly batch, and query plans that changed after the move to 11.x. Community or Enterprise Server, on premises, in the cloud or on Kubernetes. Every ticket reaches a named senior engineer.

Incident Triage

MariaDB problems we fix every week

These are real symptoms from real MariaDB production environments — and the first thing our engineers check when one comes in.

Common MariaDB production problems and how AceMQ resolves them
Symptom you're seeingWhat we check firstTypical resolution
A Galera node keeps failing state transfer and never rejoinsWhether the joiner can get an IST from the donor's gcache or is forced into a full SST, then the SST method itself: mariadb-backup credentials, ports 4444, 4567 and 4568 between nodes, and free disk on both sides. A gcache sized smaller than a normal maintenance window turns every restart into a full copy of the data.1–3 hours
After a network partition the cluster stopped accepting writeswsrep_cluster_status on every node to find which partition, if any, kept quorum, then the seqno and safe_to_bootstrap values in grastate.dat to pick the most advanced node to bootstrap from. An even number of nodes with no arbitrator is the usual root cause, so the fix includes garbd or a third site.1–2 hours
Writes stall across the whole Galera cluster at oncewsrep_flow_control_paused and each node's receive queue. Galera flow control pauses every writer until the slowest node catches up, so one node on slow storage, or one very large transaction, sets the write speed of the entire cluster.Under 1 hour
Asynchronous replicas lag for hours during the batch windowslave_parallel_mode and slave_parallel_threads, then transaction size and tables without a primary key. Under row-based replication, every row event against a table with no primary key can mean a full table scan on the replica, which no amount of parallel apply fixes.1–2 hours
A promoted replica refuses to replicate with a GTID errorgtid_slave_pos against gtid_binlog_pos and gtid_current_pos on each server, gtid_strict_mode, and the domain IDs in use. MariaDB GTIDs use a domain-server-sequence format that MySQL tooling does not understand, so failover scripts written for MySQL often pick the wrong position.2–4 hours
Undo space and disk usage grow while the data does notHistory list length in SHOW ENGINE INNODB STATUS and the oldest open transaction in information_schema.innodb_trx. A forgotten transaction or a long-running report holds a read view that stops purge, and every change made after it stays in the undo logs until it ends.Under 2 hours
Queries that were fast on 10.x are slow after upgrading to 11.xANALYZE FORMAT=JSON for the same statement on both versions. MariaDB 11.0 introduced a new optimizer cost model, so plan changes after the upgrade are expected; we refresh engine-independent statistics, compare the chosen indexes and fix the queries that regressed rather than pinning the old optimizer.Under 2 hours
Clients and replicas cannot connect after moving to 11.4TLS settings on both ends. From 11.4 the server enables SSL by default with a self-signed certificate if none is configured, clients require SSL and verify the server certificate, and replication verifies it too. Older client libraries and connection strings without a trusted certificate fail at connect time.Under 1 hour
MaxScale sends reads to a replica that is minutes behindThe readwritesplit router's replication lag limit and the MariaDB Monitor settings that decide when a server is healthy, plus whether automatic failover is configured at all. Without a lag limit, a lagging replica keeps receiving reads and the application sees stale data.Under 1 hour

What's Included

Everything in your MariaDB support contract

No add-on pricing for incidents. No per-ticket charges. One contract covers the whole surface.

  • 01

    Emergency Incident Response

    Cluster without quorum, a node that will not rejoin, replication broken, or a disk filling with undo and binary logs. A senior engineer joins a live bridge within 15 minutes with access to diagnose, not a ticket acknowledgement.

  • 02

    Root Cause Analysis

    Every P1 closes with a written RCA: what failed, why, the fix applied, and the topology, schema or configuration change that stops it happening again. Delivered as standard, not on request.

  • 03

    Galera Cluster & Replication

    Quorum design and arbitrators, gcache sizing for IST, SST method selection, flow control tuning, GTID domains and parallel replication, and MaxScale routing and failover behavior under load.

  • 04

    Query & InnoDB Tuning

    Slow query log and ANALYZE FORMAT=JSON on your real workload, index design, engine-independent statistics and histograms, buffer pool and redo sizing, and purge lag from long-running transactions.

  • 05

    CVE & Patch Advisory

    Alerts for CVEs affecting your exact MariaDB build, with tested upgrade paths. For 10.4, 10.5 and 10.6, which are past community end of life, AceMQ's OSSeva platform provides patched builds of the series you already run.

  • 06

    Upgrades & Migrations

    Rolling upgrades from 10.x to 10.11, 11.4, 11.8 or 12.3 LTS, run node by node on Galera with mariadb-upgrade, plus migrations between MySQL and MariaDB and between self-managed servers and managed services, rehearsed with a rollback plan.

Why AceMQ

What you get that you don't get elsewhere

  • Named Engineers, Zero Cold Start

    The same senior engineers stay on your account. They know your Galera topology, your replication chains and your batch windows, so a P1 call starts with a hypothesis instead of twenty minutes of context transfer.

  • No Tier-1 Triage Layer

    You reach a senior MariaDB engineer directly by phone, email or Slack. Nobody collects information to hand off, and there is no escalation approval between you and the person who can read a wsrep status dump.

  • MariaDB Is Not MySQL With a New Name

    GTID format, Galera, MaxScale, storage engines such as Aria and MyRocks, the JSON type and the 11.x optimizer all differ from MySQL. Advice written for MySQL is often wrong on MariaDB, and we know where the two diverged.

  • Galera Problems Are Usually Topology Problems

    Split brain, endless SSTs and cluster-wide stalls tend to come from node count, gcache size and one slow disk rather than from Galera itself. We fix the incident, then the layout that caused it.

  • Genuine Follow-the-Sun Coverage

    Engineers across 26+ countries and every time zone. Your 3am quorum loss is someone's mid-afternoon: no overnight skeleton crew, no waiting for a region to come online.

  • Full-Stack, Not Just mariadbd

    We diagnose across the connection pool, MaxScale, the ORM's generated SQL, storage latency, kernel settings and Kubernetes. MariaDB symptoms often have causes well outside the database process.

We support MariaDB wherever it's deployed

Cloud, Kubernetes, bare metal, hybrid, and air-gapped — including environments where you can't give us outbound network access.

Version coverage

MariaDB versions we support

The MariaDB Foundation names one long-term release (LTS) a year and ships rolling releases every quarter. From 11.8, community LTS binaries are published for three years after GA, with critical and security fixes in source releases for two more; releases up to 11.4 get five years of community binaries.

Pricing

What does AceMQ MariaDB support cost?

AceMQ MariaDB support contracts typically run $24,000–72,000 a year, depending on SLA level, scope (number of clusters or nodes, and environments) and deployment (self-managed, cloud-managed or Kubernetes).

What does AceMQ MariaDB support cost?
What moves the priceHow it changes the contract
SLA levelBusiness-hours cover costs less than 24/7 cover with a 15-minute emergency response.
ScopeMore clusters or nodes, and more environments, make a larger contract.
DeploymentSelf-managed, cloud-managed and Kubernetes estates need different amounts of hands-on work.

Covering several technologies under one contract, for example RabbitMQ, Kafka and Redis, earns an aggressive discount.

Support In Practice

Support options

Four stages of MariaDB support.

AceMQ offers MariaDB support in four stages, each handing more of the day-to-day work to AceMQ: 24/7 support and incident management for Galera clusters and replicas your team runs, proactive monitoring that finds gcache, quorum and lag problems first, managed MariaDB on your own infrastructure, and fully managed MariaDB on AceMQ infrastructure. MariaDB 10.4 to 13.x is supported, and 10.4 to 10.6 can be kept patched through OSSeva.

  • Stage 1

    MariaDB 24/7 Support & Incident Management

    You run it, we back you up

    • 15-minute P1 response for quorum loss, failed state transfers and broken replication
    • Named senior engineers who know your Galera topology and MaxScale routing
    • Community Server, Enterprise Server and Amazon RDS for MariaDB covered

    Best for: Teams that run Galera or replicated MariaDB themselves and need senior cover when a cluster splits at 3am.

  • Stage 2

    MariaDB 24/7 Support with Proactive Monitoring

    You run it, we watch it with you

    • Scheduled reviews of wsrep status, flow control and gcache sizing
    • Failover tests for MaxScale routing and replica promotion
    • CVE alerts for your exact MariaDB build, including 10.4 to 10.6 past end of life

    Best for: Teams that want the three-node cluster that cannot keep quorum, or the full SST on every restart, found in a review, not in an outage.

  • Stage 3

    Managed MariaDB on Your Infrastructure

    We run it in your cloud or data centre

    • AceMQ holds the pager for Galera nodes, replicas and MaxScale
    • Rolling upgrades run node by node, waiting for each resync
    • Backups restored and timed on a schedule

    Best for: Regulated estates that must keep MariaDB inside their own boundary.

  • Stage 4

    Fully Managed MariaDB on AceMQ Infrastructure

    We host it and run it, as a service

    • Hosted and operated by AceMQ, sized to your workload
    • Galera quorum designed with an odd node count or an arbitrator
    • Backups, upgrades and monitoring included

    Best for: Teams that want MariaDB high availability without owning Galera operations.

FAQ

MariaDB support questions

Still have questions about MariaDB? Email an Expert

What does AceMQ MariaDB support include?

MariaDB support covers 24/7 emergency incident response with a 15-minute SLA, root cause analysis on every P1, Galera Cluster and replication review, MaxScale configuration, query and InnoDB tuning, CVE and patch advisory, quarterly health checks, and upgrade or migration support. Every ticket goes to a named senior engineer assigned to your account. There is no tier-1 triage layer and no per-incident charge.

How fast do you respond to a MariaDB production outage?

P1 emergencies, such as a Galera cluster without quorum, a primary down, replication broken or a full disk, get a 15-minute first response with a senior engineer joining a live bridge. P2 critical issues are 1 hour, P3 high-priority 4 hours, and P4 standard questions next business day. These are contractual response times covering nights, weekends and holidays.

How is supporting MariaDB different from supporting MySQL?

The two share history and a wire protocol, but they have diverged far enough that MySQL runbooks mislead. MariaDB GTIDs use a domain-server-sequence format that is not compatible with MySQL's UUID-based GTIDs. Galera Cluster ships with MariaDB, so synchronous multi-primary replication, quorum and state transfer are everyday concerns. MaxScale is MariaDB's own proxy for read/write splitting and failover. MariaDB carries storage engines MySQL does not, including Aria, MyRocks, ColumnStore and Spider. JSON is an alias for LONGTEXT with a JSON_VALID check rather than a binary type, which matters for dumps and replication from MySQL. And from 11.0 the optimizer uses a different cost model. Our engineers support both, which is why we keep the advice separate.

Which MariaDB versions do you support, and when do they reach end of life?

All of them in production use, from 10.4 through the 13.x rolling releases. According to the MariaDB Foundation's maintenance policy, the current LTS lines are 10.11 (community end of life 16 February 2028), 11.4 (29 May 2029), 11.8 (4 June 2028) and 12.3 (12 June 2029). Rolling releases are maintained only until the next one replaces them: 13.0 to the fourth quarter of 2026 and 13.1 to the first quarter of 2027. MariaDB 10.6 reached community end of life on 6 July 2026, 10.5 on 24 June 2025 and 10.4 on 18 June 2024.

Do you support MariaDB 10.6 and other versions past community end of life?

Yes. We support 10.6, 10.5, 10.4 and older releases that no longer receive community fixes, because plenty of regulated and vendor-certified environments cannot upgrade on the Foundation's calendar. For security patches, AceMQ's OSSeva platform provides patched builds of MariaDB 10.4, 10.5 and 10.6 after community maintenance ends, in the same series and with the same data directory, so applying one is a normal minor update. In parallel we plan the move to a current LTS, usually 11.8 or 12.3, so the freeze has an end date.

Our Galera cluster split, or a node will not rejoin. Can you help?

Yes, and these are among the most common MariaDB calls we take. After a partition, only the side holding quorum stays Primary; the rest refuse writes to protect consistency. Recovery means finding the node with the highest committed seqno, bootstrapping from it and letting the others rejoin, without bootstrapping two sides and creating diverged data. A node that will not rejoin is usually failing SST because of credentials, firewall ports or disk space, or falling back to a full SST because the donor's gcache is too small for IST. We fix the incident first, then the node count, arbitrator and gcache sizing that caused it.

What breaks when upgrading MariaDB from 10.x to 11.x?

Three things catch most teams. The optimizer cost model introduced in 11.0 changes some query plans, so a small number of queries get slower and need index or statistics work. The InnoDB change buffer was removed in 11.0, and its settings no longer apply. And from 11.4, SSL is enabled on the server by default, clients require it and verify the server certificate, and replication does the same, so old client libraries and connection strings can fail at connect time. We rehearse the upgrade on a restored copy, run mariadb-upgrade, and on Galera roll it node by node, waiting for each node to resync before the next.

How does this compare with MariaDB enterprise support from mariadb.com?

MariaDB enterprise support is sold through mariadb.com with MariaDB Enterprise Server, and it is the source of enterprise builds and of maintenance beyond the community end-of-life dates for that product. It is worth keeping if you depend on enterprise-only builds or tooling. AceMQ supports the MariaDB you actually run, including Community Server, versions past community end of life, Amazon RDS for MariaDB, and the MySQL, PostgreSQL and other systems around it, under one contract with a 15-minute emergency SLA. Where a fault is a genuine product defect on Enterprise Server, we prepare the vendor case with the diagnosis done.

Can you help us move between MySQL and MariaDB?

Yes, in either direction. From MySQL 5.7 and earlier, the MariaDB Foundation states that mariadb-upgrade can upgrade the data files in place. MySQL 8.0 and later use a different data dictionary, so moving from 8.0 to MariaDB is a logical dump and load with compatibility testing for JSON columns, authentication plugins, collations and replication. We assess the application first, then run the migration with a rehearsed cutover and rollback.

Can we work with AceMQ on MariaDB without a long contract?

Yes. AceMQ works on MariaDB in two ways: ad hoc engagements for a defined piece of work, such as a health check, an upgrade or an incident, or an annual partner engagement that covers 24/7 support, proactive reviews and named engineers. Many teams start ad hoc and move to an annual partnership once the first engagement is done.

How much does AceMQ MariaDB support or consulting cost?

Every AceMQ proposal is tailored to your requirements: your MariaDB environment, the SLA you need, the hours of cover and the scope of work. Most contracts run $24,000–72,000 a year, depending on the SLA, the scope and how MariaDB is deployed, with aggressive discounts when several technologies share one contract.
