Identifier.java. cluster and keyspace. One problem I see is that the database is empty right now. Set up the environment used for the COPY command examples: Using CQL, create a cycling keyspace: Instead of iterating over the same bad data model a dozen times, you can now leverage highly scalable, reference data models written by Cassandra pros with years of … CQL quick reference. Cassandra Sink Example for Streaming POJO Data Type. You'll be looking at a sample dataset with just a few rows to let you get an understanding of the core concepts quickly. In addition, this POJO implementation needs to follow DataStax Java Driver Manual to annotate the class as each field of this entity is mapped to an associated column of the designated table using the DataStax Java Driver … CQL (Cassandra Query Language) is a query language for the DataStax Enterprise database.
