Redis Implementation · St Albans
Redis Implementation in St Albans
Implementing Redis for St Albans organisations, where what happens when memory fills is a decision rather than an accident. The eviction policy determines whether it discards the least recently used keys, refuses writes, or removes only keys with an expiry — and the default is frequently not what an application relying on it expects.
Why this comes up
The problem
Memory filled, the default policy started refusing writes, and the application treated a cache failure as a request failure.
What you get
What we deliver
- Eviction policy chosen against how the application uses each dataset
- Expiry set on cached keys, since keys without one accumulate indefinitely
- Memory limit configured explicitly rather than left to consume the host
- Persistence decided deliberately — whether losing data on restart is acceptable
- Data structures chosen for the access pattern rather than defaulting to strings
- Cache failure handled in the application, so a miss degrades rather than errors

Redis Implementation in St Albans — common questions
- Which eviction policy should we use?
- For a pure cache, evicting least recently used keys is usually right. For a mixture of cached and durable data, evicting only keys with an expiry protects the rest — and refusing writes suits cases where losing data silently is worse than failing loudly.
- Why does every key need an expiry?
- Because otherwise the dataset only grows. Cached values written without one stay until evicted or the instance restarts, so an application caching by user or by session accumulates keys for people who left months ago and pays for the memory.
- Is persistence necessary?
- It depends what you lose. A pure cache can be rebuilt from source and restarting empty is merely slow; if Redis holds queue state, sessions or anything not derivable from elsewhere, restarting without persistence loses it permanently.
- How should the application handle Redis being unavailable?
- By degrading rather than failing. A cache miss should fall through to the source, and a cache outage should make the application slower rather than broken — which requires deliberate handling, since the default in most clients is to raise an error.
- Do you work with businesses across Hertfordshire?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout East of England, including St Albans and the surrounding Hertfordshire area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of St Albans businesses do you usually work with?
- Professional services and consultancy systems for small firms serving London clients from a Hertfordshire base. Beyond that we work across Professional Services, Financial Services, Media, Retail and Construction.
- Do you cover the areas around St Albans?
