Riak Key-Value Pair Databases
Riak is one of the most popular open-source Key-Value Databases. It was developed and supported by a company called Basho Technologies (www.basho.com) and made available under the Apache Software License v2.0. It is known for its performance and durability with high volume and speed data. Additionally, it uses a collection key and values method that continuously helps build a manageable system.
Riak is the fastest launch of a key-value website and is scalable. It supports high-volume environments with fast-changing data because it is light-weighted and straightforward. Riak specializes in real-time analysis of financial services. It uses "buckets" to organize the collection of keys and values. Riak implementation is a collection of real or visual notes arranged peer-to-peer. There is no master node available, so the cluster is resilient and highly scalable. All data and functions are distributed throughout the collection. Riak collections have an exciting performance profile where larger clusters (with more nodes) perform better and faster than clusters with fewer nodes. Group communication is done through a unique protocol called Gossip. Gossip keeps status information about the collection and shares information about buckets.
Key-Value Databases are an excellent choice for social media, communities, and caching layers to connect to other information sites(databases). In simple terms, KVP databases are considered good options whenever we need flexibility and scalability in data storage.
Features of Riak
Riak has many features and is part of an ecosystem that includes the following:
- Parallel processing: Riak supports filtering power and also answers questions across the clusters for real-time analysis and calculation by using MapReduce,
- Links and line walking: Riak can be built to mimic a graph database using links. A link can be thought of as a one-way communication between pairs of key values. Walking (following) links will map the relationship between pairs of key values.
- Search: Riak Search has error-free, widespread search for full-text capabilities. Buckets can be indexed to adjust the value of the key quickly.
- Secondary indexes: Developers can mark values with the value of one or more key fields. An application can query the index and return a list of similar keys. This can be very helpful in using big data because it is atomic and will support real-time behavior.
Uses of Riak
Riak implementation is better suited where
- User data for social networks, communities, or games
- Collection and storage of high-volume, media-rich data
- Caching layers for connecting the RDBMS to the NoSQL databases
- Mobile applications that require flexibility and reliability
Evaluating Riak Key-Value Cluster for Big Data
The NoSQL database has become an essential alternative to traditional relational databases. Those databases are optimized for large, continuous, and flexible data management. They are widely used in cloud databases and distributed systems. With NoSQL databases, static schemes and many other restrictions are avoided. In the age of big data, such databases provide high availability solutions. Their key-value pair feature allows for faster retrieval of data and the ability to store it in bulk. There are many types of NoSQL databases with various functions. Therefore, comparing those different types of databases about performance and ensuring the relationship between performance and types of databases has become significant.
When the Riak key-value database is tested and evaluated for large data sets using measurement tools, large amounts of data are stored and retrieved in different sizes in a distributed repository. The results show that the Riak key value is stable during use on small and large data volumes, and output efficiency increases as the number of threads increases.
