Features of MemoryDB
The following are the features of the MemoryDB:
- It uses a single and primary database to work for the clusters and to provide consistency to the user application.
- A MemoryDB delivers ultra-fast performance and strong consistency to the database and helps the user to quickly build applications.
- It uses high-speed RAM or flash memory like SSDs rather than the slower hard disks to store the data in the database which is faster to read and write.
- It acts as a Load balancer by Spreading the database requests to multiple servers and distributing the work evenly so that no server is overloaded.
- It uses replicas that maintain multiple copies of the database on different servers so if one server fails, the database is still available from the other replicas.
- It is able to handle the increased data in the database and traffic in the server by easily adding more servers.
- It accesses the data in memory caches to avoid slower disk access and for the same, it uses popular caches like Redis and Memcached to store data in RAM for microsecond access.
- It is usually that memory is more expensive than disk but the performance is much better. The Declination of memory prices can help improve cost-effectiveness.
What Is Memory DB? Creating And Configuring MemoryDB Clusters
A Memory DB known as a “Memory Database” is a type of open-source data storage that is designed in such a way that it can perform the read and write operations very quickly. It is made for applications that need very high-speed data speed and low latency response. This MemoryDB is Durable in nature and was built for modern applications with microservices architectures.
A MemoryDB Cluster is made up of multiple nodes that are interconnected and distributed such that they share and manage the data very quickly. The use of the MemoryDB cluster has eliminated the need to separate and manage a cache and durable database.
