MySQL Consulting in Ely
MySQL advice for Ely organisations, where read replicas solve a capacity problem and introduce a consistency one. Replication is asynchronous, so an application that writes to the primary and immediately reads from a replica can retrieve the value from before its own update — and the bug appears intermittently, under load, in production.
Why this comes up
The problem
A user saves a change, the next page reads from a replica, and their update appears not to have happened.
What you get
What we deliver
- Read and write routing designed so a session reads its own writes correctly
- Replication lag monitored, since it varies with load rather than staying constant
- Queries directed to replicas only where slightly stale data is acceptable
- Slow query log examined, as a small number usually dominate database load
- Schema change approach agreed, because large tables lock on naive alterations
- Failover behaviour tested rather than assumed to work when needed

MySQL Consulting in Ely — common questions
- How should read-after-write be handled?
- By routing a session to the primary for a short period after it writes, or by reading from the primary for the specific operations that need it. Both work; what fails is routing all reads to replicas and assuming replication is fast enough.
- Is replication lag predictable?
- No, which is the difficulty. It is small when the system is quiet and grows exactly when the database is busiest, so the bug surfaces under load — which is also when it is hardest to reproduce and most likely to affect a customer.
- What about schema changes on large tables?
- They need an online approach. A naive alteration can lock a large table for a substantial period, so tooling that builds the change alongside and swaps it in is what makes schema evolution possible without a maintenance window nobody will grant.
- Has the failover ever been tested?
- That is the question worth asking, and the answer is frequently no. Replication configured years ago and never exercised may fail on permissions, on lag or on a step nobody documented — testing it deliberately is considerably better than discovering it during an incident.
- Do you work with businesses across Cambridgeshire?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout East of England, including Ely and the surrounding Cambridgeshire area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Ely businesses do you usually work with?
- Grower and packhouse systems handling seasonal labour, traceability and supermarket compliance requirements. Beyond that we work across Agriculture, Food Production, Tourism & Heritage, Retail and Logistics.
- Do you cover the areas around Ely?
- Yes — we work throughout East of England, including Cambridge, Peterborough, Norwich. Ely is an urban area of roughly 20,000+, and we take on work across the wider Cambridgeshire region rather than the city boundary alone.
