We cover here some missing features and details not properly addressed in the previous two articles, on migrating from a relational database to Apache Cassandra using Data Xtractor: static fields, secondary indexes, NULL values in the partition or cluster key fields etc.
Step-by-step complete functional and practical implementation of the example used by Artem Chebotko in his breakthrough whitepaper about data modeling for Apache Cassandra. The focus here is in the immediate easy migration from a relational database, and relational model, to denormalized queries and automatically generated OQL scripts.
End-to-end practical guide about denormalizing and migrating a relational database to Apache Cassandra, using Data Xtractor. It involves connecting to a PostgreSQL database from Data Xtractor, denormalizing tables through visual queries, exposing these queries in Chebotko diagrams, generating CQL scripts and data for Cassandra, and actually importing and querying data in a free cloud Cassandra instance.
