Hello JSON, Hello YAML and Goodbye XML!

Neil Stevenson

This is an example showing the use of YAML configuration, and populating a Hazelcast grid with data in JSON format that has been extracted from a traditional relational database. So the data goes from tables into “NoSQL” format. Hello YAML, Goodbye XML Hazelcast has many ways to be configured. Sensible defaults mean you don’t have […]

Riding the CP Subsystem

Ensar Basri Kahveci

The CP Subsystem of Hazelcast IDMG 3.12 offers a new linearizable implementation of Hazelcast’s concurrency APIs on top of the Raft consensus algorithm. These implementations live alongside AP data structures in the same Hazelcast IMDG cluster (new BFFs, yay!). You can store large data sets on hundreds of Hazelcast members and coordinate your operations using […]

What CAP Theorem Means to a Business Leader

Dan Ortega

The data we continuously generate and use operates on an incredibly vast scale (think of Google, Amazon, Facebook, that level of data). Because of the breadth and depth of infrastructure required to stream incoming data and execute against it (and to avoid single points of failure), the ingestion and processing of data is distributed across […]

LockSupport.parkNanos() Under the Hood and the Curious Case of Parking, Part II: Windows

Jaromir Hamala
by Jaromir Hamala | February 18, 2019

In the previous post we have seen how LockSupport.parkNanos() is implemented on Linux, what behavior to expect and how we can tune it. The post was well-received and a few people asked how parkNanos() behaves on Windows. I’ve used Linux as a daily driver for over a decade and I didn’t feel like exploring Windows. […]

The Data Processing Challenge for Continuous Intelligence

Kelly Herrell
by Kelly Herrell | February 04, 2019

The fundamental lesson from Charles Darwin’s theory of natural selection is that adaptation is the root of continuity of a species’ existence. The digital age has presented businesses the same challenge: Today’s businesses will survive or gradually die out based on whether or not they adapt to the new reality. Adaptation is a large concept.

Dan Ortega
by Dan Ortega | January 30, 2019

One of the current hot topics driving the in-memory domain is the potential associated with the application of Machine Learning technology. Like most marketing-level buzzwords, Machine Learning is something that has high awareness and low understanding, so we’ll walk through the framework of Machine Learning in this blog to add some context on what the […]

LockSupport.parkNanos() Under the Hood and the Curious Case of Parking

Jaromir Hamala
by Jaromir Hamala | January 27, 2019

When a colleague of mine was running some experiments, he noticed `LockSupport.parkNanos()` would either return almost immediately or in roughly 50 microseconds steps. In other words: Calling `LockSupport.parkNanos(10000)` would not return after 10 microseconds, but roughly after 50 μs. `LockSupport.parkNanos(55000)` would not return after 55 μs, but roughly after 100 μs, etc. The 50 μs […]
