Write-behind

In write-behind, the application does the following:

• Add/update entry in cache
• Asynchronously write entry to the data store, improving write performance

Disadvantages of write-behind:

• There could be data loss if the cache goes down prior to its contents hitting the data store.
• It is more complex to implement write-behind than it is to implement cache-aside or write-through.
