Database bottlenecks slow down performance, but identifying them helps optimize and scale effectively.

Database per Service ensures each microservice owns its data, reducing dependencies.

Search engines collect, index, retrieve, and rank documents to provide relevant results.

Choose Elasticsearch for complex text searches, but use databases for structured queries.

Database replication enhances data availability and read performance but has challenges like replication lag.

Database replication helps keep data available and allows systems to handle more read requests.

The Cache-Aside Pattern speeds up data retrieval by using a cache to store frequently accessed data.

Caching helps applications respond faster by serving data from memory instead of hitting the database.

Stateless servers are easier to scale because they don't store user session data locally.

Cache penetration occurs when requests for non-existent data overload the database.
