Learn

Before diving into administration tasks, you can save a lot of time when setting up and operating DDAC in a production environment by learning a few basics first:
  • DDAC is compatible with Apache Cassandra™ 3.11 and adds production-certified changes to Cassandra.
  • Cassandra-based applications and clusters are much different than relational databases and use a data model based on the types of queries, not on modeling entities and relationships. Architecture in brief contains key concepts and terminology for understanding the database.
  • Save yourself some time and frustration by spending a few moments looking at DataStax Doc and Search tips. These short topics talk about navigation and bookmarking aids that will make your journey through the docs more efficient and productive.

The following are not administrator-specific but are presented to give you a fuller picture of the database:

  • Cassandra Query Language (CQL) is the query language for DDAC.
  • DataStax provides drivers in several programming languages for connecting client applications to the database.
