Sample time series app based on Twitter data with Cassandra on Oracle Data Hub Cloud
The overall solution is pretty simple
Tweet Producer is a Java app which uses the Twitter streaming API to consume tweets and push them to Cassandra cluster on Data Hub
- It’s a Java app and uses twitter4j library to consume the tweet stream
- Applies user defined filter criteria/terms to filter relevant tweets from the stream
- Pushes the tweet data to Cassandra asynchronously
- It provides a REST API to start/stop the app on demand e.g. /tweets/producer
The Tweet Query service defines a REST API and interacts with Cassandra to fetch tweet data
- Its a basic Spring Boot app which leverages Spring Data and Spring Web
- The Cassandra module in Spring Data is used to interact with Cassandra
spring-boot-starter-web moduleis used to expose a REST API to query tweet related info
