Prefixed Cache Laravel Package

Product Decisions This Supports

• Multi-tenant and environment isolation: Supports decisions to share a single cache backend across tenants, apps, or environments by prefixing keys (e.g., tenant_42:, staging:, module_billing:), reducing collision and cross-tenant leakage risk.
• Shared infrastructure / cost optimization: Makes it easier to justify one Redis or Memcached cluster for multiple Laravel apps or modules instead of dedicated cache instances, lowering operational overhead and cloud spend.
• Modular monolith and microservice boundaries: Provides a simple namespace convention for feature flags, services, or rollout cohorts, helping teams scope cache invalidation and avoid key collisions during deployments.
• Build vs. buy: The package is a small PSR-6 decorator. If the only need is static key prefixing and the team already uses PSR-6 pools, buying is low-effort; if not, a 30–50 line in-house decorator may be cheaper than adding a low-adoption dependency.
• Migration and interoperability: Useful when wrapping an existing PSR-6 pool without changing call sites. It does not replace Laravel’s native cache prefixing, tagging, hierarchy, or invalidation features, so it should be treated as a tactical enabler rather than a caching platform decision.
• Dependency-risk decision: With 2 stars and 0 dependents, this should not become a critical platform dependency without an owner, fork/vendor plan, and exit strategy.

When to Consider This Package

• Adopt or prototype if:
  • You already use a PSR-6 CacheItemPoolInterface and need a consistent static prefix on every key.
  • You need quick tenant, module, or environment isolation on a shared cache without changing application call sites.
  • The use case is non-critical or internal, and the team can vendor/fork the small MIT-licensed code if maintenance stalls.
  • You are validating a shared-cache architecture before investing in a first-class tenant-aware cache abstraction.
• Look elsewhere if:
  • You are Laravel-native only. Laravel’s cache layer is not a PSR-6 pool by default; use per-store prefix configuration, Cache::store(), or a Laravel-specific wrapper rather than adding an adapter just for this package.
  • You need active maintenance, security responsiveness, commercial support, or broad community validation. The adoption signals are very weak.
  • You need tagging, hierarchy, dynamic per-request prefixes, advanced invalidation, or cache analytics. This package only adds a static key prefix.
  • You are performance-sensitive and cannot benchmark decorator overhead, key-length limits, or Redis cluster behavior.
  • Migrating existing keys or handling invalidation with prefixed keys would add more complexity than the collision risk warrants.

How to Pitch It (Stakeholders)

For executives: “We can isolate cache namespaces per tenant, app, or environment by wrapping existing PSR-6 cache pools with a small MIT-licensed decorator. That supports sharing Redis or Memcached infrastructure without key collisions and avoids dedicated cache instances for every tenant or module. It is a tactical cost and isolation lever, not a strategic caching platform. Because adoption is very low and Laravel integration requires validation, I recommend a limited pilot on a non-critical cache store. If it proves useful, we either vendor/fork the tiny codebase or implement the equivalent pattern in-house. No license cost; main risk is dependency maintenance and integration fit.”

For engineering: “PrefixedCachePool decorates any PSR-6 pool and prepends a static prefix to all keys. Use it when you already have a PSR-6 pool and need namespaces such as tenant_1:, feature_x:, or env_staging:. Pros: tiny, PSR-6-compliant, non-invasive. Cons: not Laravel-native, no tagging/hierarchy, static prefix only, and very low adoption. Integration should start with a spike using php-cache/redis-cache or the actual pool in use; wrap it via a service provider or custom cache store only after proving compatibility. Define prefix ownership, length limits, migration and invalidation behavior first. Recommendation: prototype only if PSR-6 is already in the stack; otherwise use Laravel’s native cache prefixing or build a small internal decorator.”
