What's new in Payara Server 164?

Another quarter, another release! After an eventful 2016, November brings with it the final release of the year for Payara Server. This year, we've seen new services like Request Tracing and Health Check added, as well as the Slow SQL logger and SQL Trace Listeners. Revisiting the version of the documentation from 1 year ago and comparing the amount we have added since then is, frankly, astonishing!

Despite a bumper year for both new features and bug fixes, work continues apace! Below is a short summary of some of the things to look out for in a release that caps an incredible 12 months.

Payara Server Rolling Upgrades

Any project, large or small, would ultimately like to follow industry best practices, such as continuous deployment.  In order to support this, applications must be deployed early and often.  This, in turn, triggers downtime and the users get affected by it because they could be logged out of the website, or worse, their work gets lost because the application's intermediate state is not saved - never mind the actual downtime during the application deployment process.

 

Rolling upgrades solve this problem in an efficient way!

 

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.

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. Payara Server supports a new way of clustering based on Hazelcast, which brings much more flexibility, decreases maintenance costs and adds the benefit of JCache support out of the box.

 

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.
