Advanced MariaDB Optimization Training in Copenhagen, Denmark

This advanced training is designed for experienced DBAs, system architects, and DevOps professionals who want to design and manage high-performance, high-availability MariaDB environments. It covers replication, clustering, performance tuning, query optimization, and monitoring in production systems.

PERFORMANCE OPTIMIZATION FOUNDATIONS

1. Advanced Configuration for Performance

• Tuning memory, cache, buffers
• Understanding innodb_buffer_pool_size, query_cache, tmp_table_size
• Connection and thread tuning

2. InnoDB Deep Dive

• InnoDB architecture and internals
• File structures, transactions, and I/O performance
• Tuning InnoDB-specific parameters

3. Indexing Strategies

• Choosing the right indexes
• Covering indexes and composite indexes
• When to use full-text and spatial indexes

4. Query Optimization and Execution Plans

• Using EXPLAIN, ANALYZE, and SHOW PROFILE
• Detecting inefficient queries
• Query rewriting and subquery optimization

5. Performance Schema and Monitoring Tools

• Enabling and using Performance Schema
• Monitoring with sys schema and custom scripts
• Third-party tools (Percona Toolkit, PMM, etc.)

REPLICATION AND SCALING TECHNIQUES

1. MariaDB Replication Deep Dive

• Master-Slave vs Master-Master Replication
• Semi-sync and async replication
• GTID-based replication setup and usage

2. Replication Management and Monitoring

• Replication lag detection and correction
• Handling failovers and auto-rejoin
• Backup and recovery in replicated environments

3. Proxy and Load Balancing Options

• Using MaxScale and HAProxy
• Read/write splitting and connection routing
• Load balancing best practices

4. Backup Strategies for HA

• Physical and logical backups
• Non-blocking backup with mariabackup
• Incremental and differential backup strategies

5. Performance Testing and Load Simulation

• Tools like mysqlslap, sysbench
• Creating realistic test scenarios
• Benchmarking for capacity planning

GALERA CLUSTER AND HIGH AVAILABILITY SETUP

1. Galera Cluster Overview

• Galera architecture and synchronous replication
• Use cases and limitations
• Comparison with traditional replication

2. Installing and Configuring Galera

• Node configuration and prerequisites
• Setting up 3-node (or more) clusters
• SST (State Snapshot Transfer) vs IST (Incremental State Transfer)

3. Cluster Management and Monitoring

• Starting, adding, and removing nodes
• Troubleshooting cluster split and quorum
• Monitoring with clustercheck, scripts, and dashboards

4. Tuning Galera for Performance

• Write-set optimizations
• Flow control settings and buffer tuning
• Handling large transactions and hotspots

5. Security and Disaster Recovery in HA Setups

• SSL for replication and Galera nodes
• Backup strategies in clustered environments
• Disaster recovery planning and DR testing

6. Final Review and Hands-On

• Scenario-based clustering or replication setup
• Troubleshooting and performance review
• Best practices summary and future learning paths.
