JDBC Driver for Cassandra

Build 22.0.8462

NoSQL Database

Cassandra is a NoSQL database that provides high performance, availability, and scalability. However, these capabilities are not necessarily incompatible with a standards-compliant query language like SQL-92. The driver models Cassandra tables into relational tables and translates SQL queries into calls to the Cassandra API, the CQL (Cassandra Query Language) binary protocol.

The equivalent of a table in Cassandra is a column family. Column families contain columns of related data. Like other NoSQL databases, Cassandra allows complex types of fields such as set, list, and map. A column family is a nested map data structure. This can be represented as a JSON object.

The driver offers two ways to model Cassandra objects. The Automatic Schema Discovery scheme automatically finds the data types in a Cassandra object by scanning a configured number of rows of the object. You can use RowScanDepth, FlattenArrays, and FlattenObjects to control the relational representation of the tables in Cassandra.
