Different types of caching

• Read through

  • When you read something, it checks the cache to see if it is there

  • If it's not in the cache, it will put it in the cache

  • This means data will always exist in the cache, unless the data doesn't exist

• Write through

  • When you write to the database, it will also write it to the cache

  • Also known as write aside caching

• Write behind

  • When you write to the cache, the cache knows how to persist the data to the database

Azure only supports write through caching
