Queries slow down as data grows.The database is the bottleneck
The database that ran smoothly with 10,000 records now struggles with 10 million. Queries are slow, locks are frequent, and every fix is a sticking plaster.
Signs you'll recognise
If more than one sounds familiar, it isn't a coincidence — it's a pattern.
The database underpins everything. When it slows down, the whole system slows down with it.
Why it happens
Databases are often designed for the initial scale and then grow organically. Queries that worked fine with a handful of records become unsustainable at real-world volumes.
The schema evolves without governance: new columns, new tables, new indexes. No one holds the full picture, and fixes stay one-off rather than structural.
The answer isn't always a new database — often it's rethinking how you use the one you have: query optimisation, read replicas, caching, CQRS, or breaking up the schema.
In some cases, what's needed is a change of paradigm: moving from a single relational database to a polyglot persistence strategy, with the right database for each use case.
How we step in
We work inside your organisation, not from the outside. Change happens in the code and in the teams.
Database assessment
We analyse queries, indexes, schema, locks and access patterns, and identify the root causes of the performance problems.
Query optimisation
We optimise the queries with the biggest impact: rewrites, targeted indexes, materialisation. High-impact quick wins.
Architectural evolution
We introduce read replicas, caching, CQRS or schema decomposition where needed. The database stops being a single point of failure.
Monitoring and governance
We put in place query monitoring, alerting on performance degradation, and a review process for migrations.
What changes afterwards
Faster queries
Response times stay acceptable even at high volumes.
A resilient system
Reports no longer lock up the production database.
Predictable scaling
The persistence strategy holds up against the next few years of growth.
Schema governance
Migrations are controlled, and their impact is predictable.
