Design Microservices Architecture with Patterns and Principles - Caching Strategies in Distributed Caching for Microserv

The video tutorial covers various caching strategies used in distributed microservices, including cache aside, read through, write through, and write back strategies. Each strategy is explained in terms of its operation, benefits, and drawbacks. Cache aside involves the client checking the cache before querying the database, while read through automatically retrieves data from the database on a cache miss. Write through updates the cache immediately after a database write, ensuring data consistency, whereas write back delays cache updates to reduce write operations.

What is the purpose of using caching strategies in distributed microservices?

Explain the cache aside strategy and how it operates.

What happens during a cache miss in the cache aside strategy?

Describe the read through caching strategy and how it differs from cache aside.

What is the write through strategy and how does it ensure data consistency?

How does the write back or write behind strategy differ from the write through strategy?

What are the potential drawbacks of using the write back strategy?
