DTOs mappers 4 commons ways
In a Spring Boot application using Hibernate and PostgreSQL, mapping between entities and DTOs or other data representations is essential for maintaining clean architecture and ensuring efficient data handling. Commonly used mappers for this purpose include:

Serverless functions post published
An overview of how serverless functions abstract infrastructure and where they fit in modern backends.
- PostJun 22, 2024
Server less functions
Serverless functions are a type of cloud computing service where the cloud provider automatically manages the infrastructure and scaling required to run code in response to events. These functions allow developers to focus solely on writing the code needed to perform a specific task, without worrying about the underlying server infrastructure. The cloud provider takes care of provisioning, maintaining, and scaling the servers needed to execute the functions.

MongoDB and Redis hash-function posts published
Two posts on hash-based data layout — hashed indexes in MongoDB and custom hashing strategies in Redis.
- PostJun 15, 2024
Hash Function in MongoDB
A hash function in MongoDB is used primarily for hashed indexes, which are indexes based on the hashed value of a field. Hashed indexes provide a uniform distribution of values, which can be particularly useful for sharding, ensuring even data distribution across shards.

Java Collections Framework
In Java, the Collections Framework is a unified architecture for representing and manipulating collections, allowing them to be manipulated independently of the details of their representation. It reduces programming effort while increasing performance and encourages software reuse. Here are the primary components of the Java Collections Framework:

Java 13 Text Blocks
Java text blocks, introduced in Java 13 as a preview feature and made standard in Java 15, provide a new way to represent multi-line string literals. They simplify the process of writing string literals that span several lines of code, improving readability and reducing the need for most escape sequences.

Using Custom Hash Functions in Redis
In Redis, you can indeed apply custom hash functions. Redis is highly flexible and supports various data structures that allow you to implement custom hashing mechanisms according to your requirements. Below is an overview of how you can create and use custom hash functions in Redis.
