An Introduction to Bloom Filters

The Bloom filter is a lesser-known data structure that is not widely used by developers. It is a space-efficient, highly probabilistic data structure that every developer should be familiar with. It can significantly speed up exact match queries, especially in cases where indexing has not been added to that field. The space efficiency of a … Read more

Fresh Data for AI With Spring AI Function Calls

The LLM can work with the knowledge it has from its training data. To extend the knowledge retrieval-augmented generation (RAG) can be used that retrieves relevant information from a vector database and adds it to the prompt context. To provide really up-to-date information, function calls can be used to request the current information (flight arrival … Read more
