4. Refresh Ahead

Trade-offs

	Cache-Aside	Read-Write-Through	Write-Behind	Refresh Ahead
Primary Use Cases	Read-heavy workloads, simple integration	Read-heavy workloads with requirement for high data consistency at all times	Write-heavy workloads, reducing write latency or load on data store
Consistency	Low	Strong	Eventual	Eventual
Write Latency	Higher	Same or slightly increased	Lower immediate latency	Steady
Risk of Data Loss	Low risk; race conditions do exist	Low risk	Higher risk	No risk
Complexity	Lower	Moderate	Higher	Moderate
System Load on Data Store	Potentially higher	Steady	Reduced immediate load	Steady
