Spring Data provides a powerful way to interact with your database with minimum effort. Occasionally though, you need to write custom queries to fetch or manipulate data in a more granular way. Below are some best practices you should consider when writing custom queries in a Spring Data repository.
In our last post, we looked at enriching the OpenAI model with custom data through function calls. While this technique is useful, it has its limitations and performance trade-offs. Today, we explore a more efficient way of incorporating relevant data into prompts to receive accurate and relevant model responses. Retrieval Augmented Generation, or RAG, relies on preprocessed data that is readily available upon request. In this post, we will build an Extract, Transform, Load (ETL) pipeline that stores a large corpus of weather forecasts and learn how to efficiently retrieve relevant information from a vector store.
Spring AI boosts developer’s productivity by providing seamless integration with a variety of AI models. This post explores enriching the generic model with additional data coming from custom functions. This technique known as function calling allows to elegantly tap into a variety of external data sources. However, it comes with its own challenges and considerations.
A common and effective method of validating webhook requests incorporates the use of HMAC (Hash-based Message Authentication Code) SHA256, a timestamp and signature headers. These elements combined ensure that only verified requests are processed.
Webhooks offer a robust integration with third-party services, facilitating complex and time-consuming processes asynchronously. Yet, they present a high risk of missed events due to high latency or performance issues. In this blog post, I’ll guide you through a reliable and scalable solution for handling webhooks. The toolkit consists of Spring Boot, WebFlux, Kotlin coroutines, and Apache Kafka. I’ll show you how to build a system that efficiently enqueues incoming requests into an internal queue for background processing. So let’s delve into it!
In the previous episode we learned how to load user details from a database. Now it’s on time to replace the default login form that comes with Spring Security with our own. Project Setup If you are new to this series on Spring Security and WebFlux, check my initial blog post to see how to…
