Examples of CqlTemplate

org.springframework.cassandra.core.CqlTemplate
This is the Central class in the Cassandra core package. It simplifies the use of Cassandra and helps to avoid common errors. It executes the core Cassandra workflow, leaving application code to provide CQL and result extraction. This class execute CQL Queries, provides different ways to extract/map results, and provides Exception translation to the generic, more informative exception hierarchy defined in the org.springframework.dao package.
For working with POJOs, use the {@link CassandraDataTemplate}.
