Architecture and Components
Adapter for Apache Cassandra provides a set of user interfaces and services that enable you to create integration with Datastax. The adapter is provided as a single package that must be installed on
Integration Server. For detailed installation instructions, see
Overview of installing and uninstalling
Adapter for Apache Cassandra. For software requirements, see
webMethods Adapters System Requirements .
The following diagram shows at a high level, how the adapter components connect to Apache Cassandra.
webMethods Integration Server. Adapter for Apache Cassandra is installed and runs on
Integration Server.
(WmART). The WmART package provides a common framework for
webMethods Adapter for Apache Cassandra version 10.2 and later to use
Integration Server's functionality, making Integration Server the run-time environment for
Adapter for Apache Cassandra. The WmART package is installed with
Integration Server and it provides logging, error handling for the adapter, connections, and services.
Adapter for Apache Cassandra. The
Adapter for Apache Cassandra is delivered as a single package called WmCassandraAdapter. The adapter installation includes templates from which all adapter connections, and adapter services can be created. The adapter provides:
Integration Server Administrator user interfaces that will enable you to configure and manage adapter connections
Software AG Designer user interfaces that will enable you to configure and manage adapter services
Adapter Service. Adapter services enable the
Integration Server to initiate and perform database operations on Datastax. You configure adapter services using adapter services templates, which are provided with Adapter for Apache Cassandra. For more information about adapter services, see
Overview of Adapter Services.
Adapter Connection. Adapter connections enable the
Integration Server to connect to Datastax at runtime. You must configure an adapter connection before you can configure adapter services. For a detailed description of adapter connections, see

Adapter for Apache Cassandra
Connections.
DataStax Cassandra Client API. DataStax Cassandra Client API is a client jar provided by DataStax that connects to the Cassandra cluster .
Apache Cassandra. Apache Cassandra is a high-performance, extremely scalable, fault tolerant (i.e., no single point of failure), distributed non-relational database solution. Cassandra combines all the benefits of Google Bigtable and Amazon Dynamo to handle the type of database management requirements that the traditional RDBMS vendors cannot support. DataStax is the leading worldwide commercial provider of Cassandra products, services, support, and training.
