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.
Kotlin Multiplatform unlocks new possibilities for developing cross-platform applications. However, this innovative approach does not come without its complexities. Especially when delving into its specific Gradle configuration. One of the challenges is establishing a reliable, automated test coverage report – an integral part of maintaining code quality and integrity. In this mini-series, we’ll learn how to leverage JaCoCo Gradle plugin to generate code coverage reports. Additionally, we’ll leverage GitHub Actions to generate a coverage badge independently from any third-party platform. This approach simplifies the process by keeping everything within the GitHub ecosystem, providing a seamless workflow for your multi platform projects.
Our journey of exploring authentication with Ktor has come to an end. Thanks to all of you who have followed along through this tutorial series. Over the past two months and across ten comprehensive posts, we’ve covered a wide array of techniques and best practices to secure Ktor applications effectively. For those who wish to…
Ensuring security and flexibility of web services when it comes to cross-origin resource sharing is essential. This is elegantly managed through the implementation of Cross-Origin Resource Sharing (CORS), an established practice for modern web applications. A well defined CORS policy not only enhances security but also promotes a seamless interaction between different domains. Thankfully, Ktor makes this process straightforward and efficient. In this final part of our series on authentication with Ktor, we will provide clear examples to guide you. By the end of this post, you’ll see how effortless it is to integrate CORS into your Ktor projects, ensuring your services are both secure and accessible.
