The open source database MongoDB is a popular example of a document store. Documents in MongoDB have a JSON format and are stored physically in a binary version (BSON). Indexes are supported for all attributes in any document created in the database and documents can be loaded into the database without first defining a schema. The data is automatically replicated over different nodes thus giving it a high availability. V. Zicari et al. Fig. 5 Document structure in JSON MongoDB providing different interfaces such as JavaScript, HTTP or REST [28].

Big Data Benchmarks are a good way to optimize and fine-tune the performance in terms of processing speed, execution time or throughput of the big data system. A benchmark can also be used to evaluate the availability and fault-tolerance of a big data system. Especially for distributed big data systems a high availability is an important requirement. While some benchmarks are developed to test particular software platforms, others are technology independent and can be implemented for multiple platforms.

This high level of distribution is possible due to the use of a simple data model. Cassandra uses a very unique tunable consistency model with different consistency levels where the database administrator can set the number of replica and favor consistency over availability, or vice versa. In practice this results in a tradeoff between data accuracy and response times. Cassandra has a flexible schema and comes with its own query language called Cassandra Query Language (CQL) [27]. The simple key-value data model allows for a very fast read/write performance and good scalability over various servers.
