Network partitions are an unfortunate reality when operating a distributed data grid—right up there with TCP retransmits and the discovery that your "five nines" availability calculation didn’t account for leap seconds. When a network split occurs, different partition...

Per-cache memory limits Up until now, Infinispan has required you to configure memory bounds for each cache individually. You decide how much memory each cache is allowed to consume, and the eviction machinery enforces those limits independently. Suppose you have a node w...

Welcome to the first of several blog posts that describe the segmentation of containers that Infinispan uses to store data. Some of you may have noticed in the previous 9.3.0.Final notes that we announced a new feature named “Segmented On-Heap Data Container”. We also mentio...

Infinispan hasn’t always provided a way for iterating upon entries in a distributed cache. In fact the first iteration wasn’t until Infinispan 7. Then in Infinispan 8, with the addition of Java 8, we fully integrated this into distributed streams, which brought so...

Just over a year ago we detailed some improvements to the data container, including the availability of Off Heap storage in part 2. There have been quite a few fixes for Off Heap especially around memory size estimations with Infinispan 9.2. There is also a brand new "evictio...

Infinispan has quite a few spectacular ways of executing code in the grid. But I bet you haven’t heard or aren’t really familiar with those, which is disappointing. I hope to fix this, however, as we have added more information to the user guide and wanted to deta...

As I hope most people reading this already know, since Infinispan 8 you can utilize the entire Java 8 Stream API and have it be distributed across your cluster. This performs the various intermediate and terminal operations on the data local to the node it lives on, providin...
