In the next few months, we’re going to focus on breaking down some of the streaming-specific terminology and basic concepts, and on tackling some common troubleshooting issues, all in short, 1-2 minute videos.

Here’s what we’ve done recently:

 

What is a streaming project?

In this video, learn about the basic elements of a project, and how you can combine them effectively.

 

What is an event?

Smart data streaming events are messages that contain information about an actual business transaction or occurrence. In this brief video, learn about events and their components, and see a few examples in action.

 

Methods for working with projects

There are a bunch of different ways that you can create and deploy streaming projects. This video provides a brief overview of those methods, and gives you some idea of when you might want to use one tool over another.

 

What is CCL?

In this short video, learn about CCL (Continuous Computation Language), the primary event processing language of smart data streaming, and some of its unique features.

 

What are CCL queries?

A CCL query uses Continuous Computation Language (CCL) to process data continuously in Smart Data Streaming. In this brief video, learn how these queries differ from SQL queries, and see an example of CCL queries in action.

 

What are unions?

Unions are CCL elements that bring together rows of data from windows or streams. Learn how these differ from joins, and see an example.

 

What are aggregates?

Aggregates are functions in CCL that perform summary calculations on columns. Learn about different kinds of aggregates, such as sum(), avg(), and count().

 

 

In the next few weeks, we’ll start posting some troubleshooting videos, and keep expanding on the streaming concepts. For now, take a look at the Smart Data Streaming playlist on the SAP HANA Academy YouTube channel for more videos.
