Cache invalidation is often said to be a hard problem to solve. I don't think this is true in the context of software systems. Regardless of which caching strategies you use (Write-Through or Cache Aside), the key is to have well-defined boundaries. Other boundaries cannot be modifying data within another boundary directly at the database level.
