Database Sharding · Lichfield
Database Sharding in Lichfield
Splitting a Lichfield organisation's database across multiple shards, which should be the last option considered rather than the first. The shard key is close to irreversible once data has been distributed, cross-shard queries become expensive, and most systems reaching for this still have straightforward capacity available elsewhere.
Why this comes up
The problem
Sharding has been proposed for a database whose largest table has no index on its most common filter.
What you get
What we deliver
- Cheaper options exhausted first — indexing, query work, read replicas, archiving
- Partitioning evaluated, since it solves many problems attributed to size
- The shard key chosen against real query patterns, because changing it later is severe
- Cross-shard operations identified early, including reporting and administrative queries
- Rebalancing planned, as shards grow unevenly whatever key is selected
- Migration sequenced so the system remains available throughout

Database Sharding in Lichfield — common questions
- Why is sharding the last resort?
- Because it changes everything downstream permanently. Queries, reporting, migrations, backups and transactions all become harder, and the operational burden persists for the life of the system — whereas the alternatives are reversible and frequently sufficient.
- What usually solves the problem instead?
- Indexing and archiving, more often than anybody expects. A table of hundreds of millions of rows where most queries touch the last month is a partitioning problem, not a distribution one, and missing indexes account for a striking proportion of databases declared too large.
- How is the shard key chosen?
- From the queries that matter most. A key that keeps related data together lets the common operations hit one shard, while one chosen for even distribution alone produces a system where every query fans out — and correcting that later means moving all the data again.
- What breaks that nobody anticipates?
- Reporting and admin work. Aggregations across all customers, support tools that look up arbitrary records and month-end processes all assumed a single database, and each needs rethinking — which is usually discovered after the application itself has been migrated successfully.
- Do you work with businesses across Staffordshire?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout West Midlands, including Lichfield and the surrounding Staffordshire area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Lichfield businesses do you usually work with?
- Small professional practice systems — booking, invoicing and client portals for firms with a regional rather than local client list. Beyond that we work across Retail, Tourism & Heritage, Professional Services, Logistics and Construction.
- Do you cover the areas around Lichfield?
- Yes — we work throughout West Midlands, including Birmingham, Stoke-on-Trent, Wolverhampton. Lichfield is an urban area of roughly 35,000+, and we take on work across the wider Staffordshire region rather than the city boundary alone.
