RocksDB is a key-value database written in the C++ programming language. A key-value database is a type of database that stores data in the form of key-value pairs, where the key is a unique identifier that is used to retrieve the corresponding value.
RocksDB is based on LevelDB, an open-source key-value store developed by Google, and was developed by Facebook to be used as a backend for their applications that require high performance and scalability. This database is designed to be a high-performance embedded database, meaning that it can be easily integrated into other applications as a library.
One of the main advantages of RocksDB is its support for advanced features such as compression, snapshotting, and fast recovery from failures. Compression can help reduce the amount of disk space used by the database, while snapshotting allows for easy backups and recovery of the database.
RocksDB also supports a feature called column families, which allows for the storage of multiple types of data in the same database. This can be useful for applications that need to store different types of data, such as structured and unstructured data, in the same database.
This database has been used in a number of high-performance applications, such as HBase and MySQL. It is also supported by a number of cloud services, including Amazon DynamoDB and Google Cloud Bigtable, which provide managed instances of RocksDB as a service.
In conclusion, RocksDB is a high-performance and scalable key-value database that is widely used in various types of applications. Its advanced features and ease of integration make it a popular choice among developers and companies. If you are interested you can visit the official page here.
