O 11º encontro do Coimbra JUG marca o 2º aniversário!

Irá estar presente um orador internacional: a Heather VanCura da Oracle.

Learn how to take part in Java technology evolution. You can participate as an individual, corporation, or nonprofit such as a Java user group (JUG). This session gives you step-by-step instructions on how to participate in the JCP Program. You will also learn about the global
Adopt-a-JSR program and how you can participate in the Adopt-a-JSR program and Adopt OpenJDK programs. We will discuss details such as how to run hack days, collaborate with other JUG leads on Adopt-a-JSR activities, and review use cases from other JUGs around the world contributing to the Java EE 7 and Java SE 8 JSRs. Currently there are new JSRs being submitted and developed for the Java EE 8 and Java SE 9 platforms. Find out how you have contribute to the future editions of the Java Standard and Java Enterprise Editions.

Distributed Computing with Hazelcast - Coimbra JUG - 9DEZ2015

Data: Quarta-feira, 9 de Dezembro de 2015
Hora: 18:15

O 12º encontro do Coimbra JUG marca também o 2º aniversário! Para comemorar a ocasião algumas surpresas irão haver neste evento.

Irá estar presente um orador internacional: o Christoph Engelbert da Hazelcast.

Nowadays collected amounts of data growing exponentially. More than 75% of all stored data were collected in the last 5 to 6 years. To store and D those always fast growing pile of data we have to go new ways. The Scale-Up approach starts to break apart. Partitioning data and parallelize processing and analyzing are the new way.
Our interactive journey will give a short introduction into Distributed Computing and In-Memory Computing with Hazelcast. A few slides and lots of live-coding and hopefully lots of discussions and questions.

Book - High-Performance Java Persistence

About the book

This book is a journey into Java data access performance tuning. From connection management, to batch updates, fetch sizes and concurrency control mechanisms, it unravels the inner workings of the most common Java data access frameworks.
The first part aims to reduce the gap between application developers and database administrators. For this reason, it covers both JDBC and the database fundamentals that are of paramount importance when reducing transaction response times.
The second part demonstrates how you can take advantage of JPA and Hibernate without compromising application performance.
The third part is dedicated to jOOQ and its powerful type-safe querying capabilities, like window functions or common table expressions.
