What is MongoDB's document model?

Instead of storing data in rigid relational tables (rows and columns like SQL databases), MongoDB stores data as flexible JSON-like documents that can have different structures — this makes it easier for developers to work with complex, hierarchical, or evolving data without schema migrations.

What is vector search?

Vector search allows databases to find similar items based on semantic meaning — storing data as mathematical vector embeddings and then searching for items with similar embeddings. This is a key capability for AI applications like semantic search, recommendation engines, and RAG (retrieval-augmented generation) for LLMs.

How do streaming and database platforms complement each other?

Real-time streaming platforms (Confluent) move data between systems as events happen, while database platforms (MongoDB) store and retrieve that data for application use — they address different layers of the data stack and can work together in modern architectures.
