Write-behind (write-back)
Introduction
Source: Scalability, availability, stability, patterns
In write-behind, tha application does the following:
- Add/update entry in cache
- Asynchronously write entry to the data store, improving write performance
Disadvantage(s) : 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.
