I had a workshop at Kafka Meetup Tel Aviv in May 2018: “KSQL Deep Dive – The Open Source Streaming SQL Engine for Apache Kafka“.
Here are the agenda, slides and video recording.
“Getting Started with NoSQL” is a new book by PACKT PUBLISHING. It gives an introduction to different NoSQL concepts and products. Besides, it explains the differences to SQL databases and when to use which one.
First, the book defines NoSQL and explains what it is and what it is not. Especially, the characteristics and differences compared to SQL are described. The next chapter explains most important NoSQL storage types: Column-oriented databases, document stores, key-value stores, and graph databases. Advantages and disadvantages of these concepts are explained in detail, before comparing most important NoSQL products such as Cassandra, Neo4j, MongoDB or Redis. A case study (which uses MongoDB) concludes the book to show how an implementation with a NoSQL database is different from using a relational database.
Spring Roo is a tool to offer rapid application development on the Java platform. I already explained when to use it: http://www.kai-waehner.de/blog/2011/04/05/when-to-use-spring-roo. Spring Roo supports two solutions for Cloud Computing at the moment: Google App Engine (GAE) and VMware Cloud Foundry. Both provide the Platform as a Service (PaaS) concept. This article will discuss the GAE support of Spring Roo. Cloud Foundry will be analyzed in part 2 of this article series.
MyBatis (http://www.mybatis.org/) is a lightweight persistence framework for Java and .NET. This blog entry addresses the Java side. MyBatis is an alternative positioned somewhere between plain JDBC and ORM frameworks (e.g. EclipseLink or Hibernate). MyBatis usually uses XML, but it also supports annotations since version 3.
