Working with Apache Cassandra: Indexes Aggregations & Programmatic Access

Apache Cassandra is a distributed NoSQL technology meant for large-scale data so programmatic access to Cassandra is especially important. Cassandra supports client libraries in several major programming languages like Java Python and C#. Developers use these to connect to Cassandra and to work with it from code. Begin by creating and using indexes in Cassandra. Then define and invoke user-defined functions (UDFs) to perform aggregations. Finally you’ll create a Java Maven project with the datastax library as a dependency and connect to a Cassandra database using that library. You will create a Cassandra session execute various operations using the datastax APIs and confirm that these queries went through successfully. Upon completion you will be able to create indexes on Cassandra tables perform grouping and aggregation operations leverage UDFs and work programmatically with Cassandra from a Java client.
