MySQL databases that stay fast as you grow
MySQL is a mature open-source relational database supported by almost every host, framework and CMS. It is a sound choice for read-heavy web applications and platforms such as WordPress and Magento that expect it.
MySQL is fast for typical web workloads, simple to host and well understood by operations teams, and managed versions are available on every major cloud. Its SQL feature set is narrower than PostgreSQL in some areas, and behaviour around strict modes and character sets needs care to avoid subtle data issues. For new systems with complex reporting or heavy use of JSON and extensions we often lean towards PostgreSQL, but for existing MySQL estates we tune rather than migrate unless there is a clear gain.
What we build with MySQL
- Schema design and normalisation
- Slow-query analysis and indexing
- Replication and read-replica setup
- Upgrades and character-set fixes
- Migrations to managed cloud databases
MySQL questions
Should we move from MySQL to PostgreSQL?
Not automatically. If MySQL meets your needs, tuning is cheaper and lower risk. We recommend a move only when a specific feature or limitation justifies it.
Why is our MySQL database getting slower?
The usual causes are missing or unused indexes, unbounded queries and growing tables without archiving. A query audit normally identifies the main culprits quickly.
Which MySQL storage engine should we use?
InnoDB, in almost every case. It supports transactions, row-level locking, foreign keys and crash recovery, whereas older engines such as MyISAM lack those guarantees.
How do you back up a MySQL database safely?
We use consistent logical dumps for smaller databases and physical backup tools for larger ones, with binary logs retained for point-in-time recovery. Restores are rehearsed so recovery time is known in advance.
How does MySQL replication work?
A primary server records changes in its binary log and replicas apply them, which lets you move read traffic and backups off the primary. Replication is usually asynchronous, so we account for small delays when reading from replicas.
Why do we see garbled characters or broken emoji in MySQL?
This is usually a character-set mismatch, often tables using the older three-byte utf8 set instead of utf8mb4. We convert tables and connections to utf8mb4 with a matching collation, testing the change on a copy first.
How do you change a large MySQL table without downtime?
Many changes can run as online DDL, and for heavier ones we use online schema-change tools that copy the table in the background. We schedule and monitor these carefully on busy systems.
What does strict SQL mode do in MySQL?
Strict mode makes MySQL reject invalid or truncated values instead of silently adjusting them. We keep it enabled so data errors surface as failures rather than quietly corrupting records.
Is a managed MySQL service worth it?
For most businesses, yes. Managed offerings handle backups, patching, replicas and failover, leaving your team to focus on schema and query quality.
How do you monitor MySQL health?
We track the slow query log, connection counts, replication lag, buffer pool usage and disk growth, with alerts on the metrics that predict trouble. Performance Schema helps pinpoint which queries cause load.
