Today I Learnt 

 

Busy with school assignment

Assignment prac 1 : 

 

• You check the (Redis) cache as before. If it is there, serve it.

• If it isn’t there, you check to see if it is in S3. If it is in S3, serve it, but also store it in the cache.

• If it isn’t in S3 either, go and get it from Wikipedia and store it in S3 and in the Cache

 

.

Redis -

One type of database by key:value format.

Fast since its stored in the cache 

 

Caching is the process of storing data into a cache. A cache is a temporary data store where data is kept for later use.

A cache as a data store is easier for the client (or server) to reach, as opposed to a permanent data store that might be located on a different service, which takes more time and resources to reach (a database or an external API endpoint)
