Integrating with Cloudant and many other RESTful Services

Streams integrates with other technologies using adapters to popular protocols such as TCP, ODBC, Kafka, JMS, MQTT and HDFS, just to name a few. REST is another established protocol that is gaining popularity because of its use in many cloud-based services. This article describes how to use Streams HTTP adapters to integrate SPL applications to Cloudant and other RESTful, web-based services.

Reading from an external source—such as the network or filesystem—is often a performance bottleneck. When source operators are the performance bottleneck for a streaming application, we have a tendency to blame the reading from the external source. But, that is not always the case. Particularly for large tuples which have many attributes, the actual performance bottleneck can be parsing. Continue reading Parallelized File Processing with the Parse Operator
