Releem: Automatic MySQL configuration tuning tool

As data and traffic grow, MySQL’s original configuration often stops matching the workload. Settings like innodb_buffer_pool_size, connection limits, and cache sizes become outdated, which leads to wasted memory, higher disk I/O, and slower queries. Manually tuning these parameters is time consuming, and most teams cannot keep up as workload patterns evolve.

Releem keeps your MySQL configuration continuously optimized. It analyzes real workload metrics, identifies inefficient settings, and recommends or applies safe improvements automatically. This removes the need for manual tuning and helps your database stay fast and stable without ongoing effort.

Releem follows a continuous five-stage process to keep your MySQL configuration aligned with its workload while leaving you in control of production changes.

1. The Releem Agent collects MySQL and system metrics every minute, including memory usage, I/O patterns, connections, and query activity.
2. Releem analyzes these metrics alongside your current configuration, database version, deployment environment, and preferences.
3. Releem generates recommendations using two complementary methods:

• Deterministic rules handle recommendations derived from configuration analysis, health checks, and user-defined preferences. Examples include query-truncation limits, connection capacity, and durability settings.
• Releem’s machine learning model evaluates compatible configuration alternatives and selects the overall configuration predicted to reduce 99th-percentile (P99) query latency while satisfying safety and compatibility constraints.

4. Releem presents the resulting configuration as a reviewable set of parameter changes, with an explanation and expected impact for each recommendation.
5. You decide when and how to apply the configuration, either manually or through automation you configure.

As your workload changes, Releem repeats this process so that your configuration can evolve with actual database usage.

Releem tunes over 40 MySQL configuration parameters across memory allocation, connections, disk I/O, caching, and thread management.

The optimization includes key settings such as innodb_buffer_pool_size for memory efficiency, max_connections for connection handling, innodb_log_file_size for write performance, and table_open_cache for metadata access.

Releem determines optimal values by analyzing real workload behavior, ensuring your configuration stays aligned with how the database is actually used.

Releem gives you full control over how configuration updates are applied. You can review each recommended change in the dashboard, apply it manually, or enable automated updates through a cron job.

Whenever possible, Releem applies configuration changes without restarting MySQL by using dynamic parameters that can be updated on the fly. If a change requires a restart, the dashboard clearly indicates it so you can plan accordingly.

Before any update is applied, Releem verifies memory limits, parameter dependencies, and MySQL version compatibility. After changes are applied, the agent monitors the server to confirm stability, and automatically rolls back to the previous configuration if any issue is detected.

This workflow allows teams to improve performance safely without disrupting production or maintaining manual scripts.

Releem tracks performance before and after each configuration update, making it easy to confirm whether tuning improved your workload. Key MySQL and system metrics are recorded continuously, and any changes in behavior are highlighted in the dashboard.

You can evaluate improvements using metrics such as query latency, QPS, buffer pool hit ratio, disk I/O, slow queries, CPU usage, and memory utilization. Releem also records when each tuning action was applied, allowing you to correlate configuration changes with performance trends.

This visibility helps you understand the real effect of each update and ensures that tuning decisions lead to measurable gains in performance and stability.

Releem keeps a full history of configuration changes so you can compare how different settings affected performance over time. Each version of the configuration shows the exact parameter values, the metrics collected during that period, and the measured impact on workload behavior. This allows you to review how tuning influenced latency, throughput and resource usage.

You can switch between configurations in the dashboard, view the differences, and correlate them with performance trends. This makes it easy to understand why a change was beneficial, whether it needs adjustment, or if reverting to a previous configuration would be more effective.

Built around the idea that managing database servers should be straightforward, Releem handles all the complex backend work of monitoring and optimizing your database for peak performance:

1. Health checks - Releem continuously evaluates key MySQL and system metrics to highlight issues that need attention.
2. SQL query optimization and index suggestions - Releem detects inefficient or repetitive queries, identifies missing indexes, and provides actionable recommendations to improve execution speed.
3. Schema optimization - Releem checks schema and index structures to detect issues that slow down queries, such as missing or inefficient indexes, and suggests safe improvements without requiring application code changes.
4. MySQL monitoring - By tracking workload metrics, Releem identifies performance bottlenecks early, helping you stay ahead of problems without manual investigation.
5. Broad compatibility - Releem works with MySQL, MariaDB, Percona Server, and cluster configurations including Percona XtraDB Cluster, Galera Cluster, and InnoDB Cluster. It supports both self-hosted and cloud-managed databases on AWS RDS, Google Cloud SQL, and Azure Database.
