This week The apache Ignite book becomes one of the top books of leanpub.

Recently we made a massive update on our lean publishing book The Apache Ignite Book . The book still is in progress. However, for the developers who intended to a quick start with Apache Ignite, we restructured the Sample chapter such a way that can be used as a  quick start guide . We included the entire chapter 2 Getting started with Apache Ignite and most of the part of chapter 4 Architecture deep dive . We believe the best way to learn something new is to jump right in and do a simple example to play around it. Whenever you had a decent overview of what you could do with this technology, you could always find more details later. The document is well structured and guides you from installing and running Ignite to write an advanced application to read and write data from/to the Apache Ignite database. The Apache Ignite quick start guide covers the following topics: Chapter: Getting started with Apache Ignite Installing and setting up Apache Ignite. Running multiple instances

Ignite Baseline Topology or BLT represents a set of server nodes in the cluster that persists data on disk. Where, N1-2 and N5 server nodes are the member of the Ignite clusters with native persistence which enable data to persist on disk. N3-4 and N6 server nodes are the member of the Ignite cluster but not a part of the baseline topology. The nodes from the baseline topology are a regular server node, that store's data in memory and on the disk, and also participates in computing tasks. Ignite clusters can have different nodes that are not a part of the baseline topology such as: Server nodes that are not used Ignite native persistence to persist data on disk. Usually, they store data in memory or persists data to a 3rd party database or NoSQL. In the above equitation, node N3 or N4 might be one of them. Client nodes that are not stored shared data. To better understand the baseline topology concept, let’s start at the beginning and try to understand its goal and what
