NHibernate performance issues #3: slow inserts (stateless session)

By
The whole series of NHibernate performance issues isn't about simple use-cases. If you develop small app, such as simple website, you don't need to care about performance. But if you design and develop huge application and once you have decided to use NHibernate you'll solve various sort of issue. For today the use-case is obvious: how to insert many entities into the database as fast as possible? Why I'm taking about previous stuff? The are a lot of articles how the original NHibernate's purpose isn't to support batch operations , like inserts. Once you have decided to NHibernate, you have to solve this issue. Slow insertion The basic way how to insert mapped entity into database is: SessionFactory.GetCurrentSession().Save(object); But what happen when I try to insert many entities? Lets say, I want to persist 1000 libraries each library has 100 books = 100k of books each book has 5 rentals - there are 500k of rentals  It's really slow! The inser

Using CoreOS stack and Kubernetes #2: Why use CoreOS as Cloud Operating System

By
I'd like to deal in this part with potential benefits resulting from using CoreOS as an operating system in your cloud deployment. You can install kubernetes on various operating systems  so you can make a decision what to choose. So why CoreOS? What is my experience? Etcd, Fleet and Flannel Preinstalled First reason is obvious. CoreOS always provides latest version of all components in Kubernetes cluster.  My experience : we have profited from pre-installed components from the beginning. E.g. in early stages when etcd was coming with new beautiful and powerful API (v.2), they put both - old and new - versions together so we just enabled one of them. The setup of all components together is not very simple so you can save couple hours by choosing preinstalled and pre-setuped CoreOS. No Package Manager, Read Only Partitions It sounds more like disadvantage than benefit, but ... Look at CoreOS releases what it consist of. Fore example, CoreOS includes basic
