Data and indexes are stored in similar formats in memory and disk to avoid complex format conversions, and datasets are simply moved between memory and disk

The Apache Ignite Memory Data organization Framework is a high-performance, integrated, and distributed memory computing and transaction platform for large-scale dataset processing with higher performance than traditional disk-based or flash technologies, while providing high performance for applications and dif
GridGain confirms that Apache Ignite has twice the performance of Hazelcast
A provocative blog written by Mr. Greg Luck, CEO of Hazelcast, accused the Apache Ignite community of "Forging" test results. This blog has caused some confusion, I think it is necessary for me to clarify.
Honestly, we are very surprised to see
This article assumes that the reader understands the Apache Ignite, has read the official documentation of the Ignite service grid, or has used a Ignite service grid, and this article also assumes that the reader understands the relevant uses of Java's completionstage. The ignite
Apache Ignite Memory Data organization is a high-performance, integrated, and distributed memory platform that performs transactions and calculations in real-time in large data sets, with an order of magnitude improvement over traditional disk-or flash-based technologies.Storing data in the cache can significantly increase the speed of your application, because caching can reduce the frequency of data being

This behavior is due to peer class loading, a special kind of distributed class loading, you can exchange bytecode between the clusters, using Peer class loading, Your Java code or Scala code does not have to be published manually or republished to the cluster machine due to changes in business needs.The document says so, but now the 1.3.0-incubating,

Through the introduction of the previous article, "Architecture Design: The basic concept of inter-system communication (--RPC)", I believe the reader has understood the basic RPC concept. In order to deepen this understanding, I will explain in detail a typical RPC specification implementation of Apache Thrift in the following articles. Apache Thrif
