Persistent EJB Timers in Payara Micro

Payara Micro is packed with most of the features and APIs that come with Payara Server Full Profile even though it doesn't entirely support whole Jakarta EE Full Profile. As an example, Payara Micro supports persistent EJB Timers, which are only required by the Jakarta EE Full Profile and not by the Web Profile. In Payara Micro, it's possible to use persistent EJB Timers, which are stored across your micro instances inside the distributed data grid as long as at least one instance in the data grid is up and running.

What's new in Payara Server 163?

As we enter the third quarter of the year, that can only mean one thing: Payara Server 163 is here!

One of these new features is the tech preview of our new Request Tracing service, which I’ll explain in more detail below.

 

Flexible Clustering with Payara Server

Application server clustering provides a means to make application infrastructure more robust and perform better. However, it is often very inflexible and even a small change in the cluster topology can involve serious maintenance costs.

Java EE Microservices Platforms & High Performance Java EE with JCache– jDays 2016

Recently I attended as a speaker at my second jDays, a great conference in a great venue in Gothenburg. jDays is a fantastic conference as it is small enough to easily meet people and network and discuss tech, while at the same time big enough to run multiple tracks so there is always a session on that you’ll be interested in. 

 

Flexible HA & Scalability Architectures with Payara Server


One of the lesser known features and key benefits of Payara Server is that it provides huge flexibility when architecting topologies for High Availability and Scalability. Utilising the embedded Hazelcast Data Grid for web session and JCache clustering brings the potential of many different topologies for scale out.
