A common idea for using Ignite is to import the data from an existing relational database into ignite and then use the data directly in ignite, which is equivalent to ignite as a caching service, and of course ignite functions much more than that. The following is a demonstr
that no clients are currently connected to this cluster.
At this point, we can run the same command on another machine to start a Ignite, and then we can see
...
[00:41:21] Topology snapshot [ver=2, servers=2, clients=0, cpus=2, ...
] ...
You can see servers=2 that a new node has joined the cluster. Test
The Ignite cluster is already available, so let's look at

When a node fails or other calculations occur, the task is automatically transferred to other nodes in the cluster for execution

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 blog from Hazelcast. Should Mr. Luck be
The previous article describes how to install and use the Ignite cache. Today talk about Ignite cache transactions.
In our usual development there is often a scenario where two or more threads are simultaneously manipulating a cached data, at which point we want either to succeed or fail. This kind of scene is very common in the database of the number relation, it is realized through the transaction process
1. OverviewApache Ignite, like Apache Arrow, is a memory distributed management system in the Big Data category. Arrow is described in Apache arrow memory data, which unifies the data formats of various ecosystems in the big data domain, avoiding the resource overhead associated with serialization and deserialization (which can save around 80% of CPU resources). Today to give you an analysis of the Apache Ignite
In the Ignite distributed cache, there is a common application scenario is distributed lock, the use of distributed locks we can achieve a simple cluster master election function.
Here is an example of using a distributed lock:

Apache ignite--New Generation Database caching system Apache Ignite is a universal database caching system that supports not only all underlying database systems, such as RDBMS, NoSQL, and HDFs, Optional features such as Write-through and read-through, Write-behind caching are also supported."Editor's note" The rapid growth of data requires a lot of storage, the management of these data is not an easy task.

It is fortunate to have participated as MVP in this annual Microsoft China Technical Conference (Ignite). Jumping out of the technical field, this meeting gave me the greatest feeling is attitude. In recent years, whether it is open source technology, or the release of black technology, people feel that Microsoft is becoming cool, but cool is not necessarily popular will not necessarily be successful. Also have "attitude", this Conference continues th
Currently used is the latest hatching version: 1.3.0-incubating.Official document Https://apacheignite.readme.io/docs/zero-deployment a distributed class loading mechanism (distributed ClassLoader) is given here.The document says so:The closures and tasks that you have with for your computations is the any custom class, including anonymous classes. In Ignite, the remote nodes would automatically become aware of those classes, and you won ' t need to e
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 transmitted in your application and database
