Both Kafka and MemSQL are unusual in supporting exactly-once updates , a key feature that not only adds valuable capabilities, but affects how you think about data movement within your organization. In this figure from the full Streaming Systems ebook, Kafka and Spark both appear as relatively recent arrivals. Apache Spark and Streaming Apache Spark is an older streaming solution, initially released in One of the key components included in the 1.
While widely used, Spark is perhaps as well known today for its machine learning and AI capabilities as for its core streaming functionality. In this chapter, the authors discuss how to use SQL robustly in a streaming environment.
Streaming Joins is Chapter 9. Joins are foundational to analytics, and optimizing them has been the topic of decades of work in the SQL community.
Yet joins are often neglected in the NoSQL movement that is most closely associated with streaming. Streaming Systems shows how to use joins in a streaming environment.
Next Steps to Streaming We recommend that you download and read our book excerpt from Streaming Systems today. If you wish to move to implementation, you can start with MemSQL today for free. Hernandez wrote one of the clearest and simplest tutorials on writing effective SQL queries.

There are two basic issues to focus on when tuning SQL: how to find and interpret the execution plan of an SQL statement and how to change SQL to get a specific alternate execution plan. Learning SQL moves you quickly through the basics and then on to some of the more commonly used advanced features.
Among the topics discussed: The history of the computerized database SQL Data Statements--those used to create, manipulate, and retrieve data stored in your database; example statements include select, update, insert, and delete SQL Schema Statements--those used to create database objects, such as tables, indexes, and constraints How data sets can interact with queries The importance of subqueries Data conversion and manipulation via SQL's built-in functions How conditional logic can be used in Data Statements Best of all, Learning SQL talks to you in a real-world manner, discussing various platform differences that you're likely to encounter and offering a series of chapter exercises that walk you through the learning process.
Even if you are using a tool that generates SQL for you, such as a reporting tool, there may still be cases where you need to bypass the automatic generation feature and write your own SQL statements.
