What is an In-memory database?
An in-memory database is a way to store data and access it in the fastest way possible.
An in-memory database is a database where data is stored in the memory of computers, as opposed to traditional databases which use SSDs or hard drives.
Best when speed and availability is key
This type of database is particularly useful when dealing with data that need to be accessed in real-time or really quickly: think of gaming platforms, real-time biding or embedded software systems. However, it comes at a price: by default, data stored in in-memory databases is not persistent and can be lost in case of crash.
Benefits of using In-memory databases
- Low latency
- Fast response time
Use cases for In-memory databases
- Caching layer for persistent databases
- Real-time applications (gaming, banking, biding)
- Embedded software systems
