An in-memory database is a type of database management system that primarily relies on a computer's main memory (RAM) for data storage and processing, as opposed to traditional disk-based systems. This approach significantly reduces data access times and improves query performance, making it ideal for applications requiring rapid data processing and real-time analytics.
DuckDB is a prominent example of an in-memory database, designed specifically for analytical workloads. In-memory databases can handle large volumes of data efficiently, often employing compression techniques to maximize memory usage. While the data resides in RAM during operation, many in-memory databases also provide mechanisms for persistence, such as snapshots or transaction logs, to ensure data durability in case of system failures.
