Cache-Aside Pattern

Benefits

• Improves application performance

• Ensures Consistency of your data in cache

• Static data sets
• Caching session state information

To use when

• Current cache does not provide read-write-through
• Dealing with unpredictable data usage

To Not use when

How it works

Read-Through

Write-Through

Considerations

• Expiration of data should match the use by the application
• Data eviction to be applied regarding caching cost
• Consider using Prime cache strategy in combination with cache aside
• Consistency of data is jeopardize for multi-applications data store
• Local (In-Memory) Caching VS Distributed caching mechanism
