Yesterday i visited Saint Petersburg university after a long period of time as a speaker. Conference held already a weeks and students came here from all over the country and out side of Russia. Audiences was very nice and ask a lot of technical question mostly about Cassandra and we are utilising it in our projects. Community was very curious about NoSQL and wanted find all the answer of their questions about the new trend. Here is the presentation from slide share net.
Any technology, no matter how advanced it is, will not be able to solve your problems if you implement it improperly. Caching, precisely when it comes to the use of a distributed caching, can only accelerate your application with the proper use and configurations of it. From this point of view, Apache Ignite is no different, and there are a few steps to consider before using it in the production environment. In this article, we describe various technics that can help you to plan and adequately use of Apache Ignite as cutting-edge caching technology. Do proper capacity planning before using Ignite cluster. Do paperwork for understanding the size of the cache, number of CPUs or how many JVMs will be required. Let’s assume that you are using Hibernate as an ORM in 10 application servers and wish to use Ignite as an L2 cache. Calculate the total memory usages and the number of Ignite nodes you have to need for maintaining your SLA. An incorrect number of the Ignite nodes can become a b...
