The post discusses an innovative approach to optimizing database storage using string interning in Rust, effectively reducing the size of a time series database by 2000 times. The technique involves interning strings to prevent duplication and thus minimize memory usage. The author shares experiences from past implementations, particularly contrasting inefficient methods with the more effective Rust-based solution they developed. The use of interning not only speeds up processes but also allows for efficient memory management, making the database comparison operations fast and light on resources. Comments reflect interest in string interning techniques and praise the author's iterative approach to problem-solving, while also highlighting the broader implications of efficient data handling in programming.
