WSO2 DAS receives data published by Data Agents through Event Receivers. Each event receiver is associated with an event stream, which you then persist and/or process using Event Processors. There are many transport types supported as entry protocols for Event Receivers in WSO2 DAS. For more information on Event Receivers, see Receiving Events.
Analytics REST API
In addition to the Event Receivers, WSO2 DAS facilitates REST API based data publishing. You can use the REST API with Web applications and Web services. For more information on REST API, see Analytics REST API Guide.
Data Store
WSO2 DAS supports Data Stores (Cassandra, HBase, and RDBMS etc.)
for data persistence. There are three main types of Data Stores, namely Event Store, Processed Event Store, and File store. Event Store is used to store events that are published directly to the DAS. Processed Event Store is used to store resulting data processed using Apache Spark analytics. File store is used for storing Apache Lucene indexes. For more information on Data Stores, see DAS Data Access Layer.
