Details

We are pleased to bring you the eighth event of the Docklands.LJC (http://docklandsljc.uk); a group within the main London Java Community that focuses on the developer community in and around Docklands on the 2nd Tuesday of each month. Our speakers this month are Akmal Chaudhri and Christos Erotocritou. Please note the location for this event as it is in a different location from the previous one. As the spaces are limited places will be preferentially allocated to those who have attended previously and first-timers; those with a low attendance record may be removed.

Akmal Chaudhri - Selecting a NoSQL database from a menu of over 200 products

Today, there are thought to be over 200 commercial and open source NoSQL database products. Often, these products are divided into four broad categories: key-value stores, column stores, document stores and graph stores. Increasingly, some products are combining several of these categories together into what are called multi-model database systems.

Whilst the market for NoSQL database systems today is still very small and thought to be around 2% of the SQL market, the technology has attracted interest from organizations looking to solve new business problems. However, since it is still an emerging technology, careful consideration is required in finding the relevant developer skills and choosing the right product.

This presentation will discuss these issues in greater detail. In particular, it will focus on some of the leading NoSQL database products and discuss their architectures and suitability for different problems. Java code examples will be used to demonstrate Create, Read, Update and Delete (CRUD) operations for several leading NoSQL database products.

Christos Erotocritou - Introducing Apache Ignite

Apache Ignite is a high-performance, integrated and distributed in-memory platform for computing and transacting on large-scale data sets in real-time, orders of magnitude faster than possible with traditional disk-based or flash technologies.

During this session you’ll learn about the Apache Ignite project and how it is used to solve some of the most demanding scalability and performance challenges. We will cover a few typical use cases and work through some examples.

Who should attend

Anyone who is interested in Java or JVM based technologies, whether in the Docklands or further afield, is welcome to attend.
