Connection pooling reuses database connections but can cause issues if misconfigured.

REST, RPC, and gRPC are different methods for communication in software systems.

Idempotency ensures that repeated operations in APIs do not cause duplicate effects.

gRPC allows efficient communication between services using a structured request-response model.

FAANG interviewers evaluate problem understanding, architecture, scalability, and communication skills.

HTTP methods tell the server what to do, and status codes tell us the result.

Microservices can communicate using five key patterns based on their needs.
