A scalability evaluation on CockroachDB

Sammanfattning: Databases are a cornerstone in data storage since they store and organize large amounts of data while allowing users to access specific parts of data easily. Databases must however adapt to an increasing amount of users without negatively affect the end-users. CochroachDB (CRDB) is a distributed SQLdatabase that combines consistency related to relational database management systems, with scalability to handle more user requests simultaneously while still being consistent. This paper presents a study that evaluates the scalability properties of CRDB by measuring how latency is affected by the addition of more nodes to a CRDB cluster. The findings show that the latency can decrease with the addition of nodes to a cluster. However, there are cases when more nodes increase the latency.
