Ignite distributed ComputingIn the ignite, there are distributed computation of the traditional MapReduce model, and the collocated computation based on distributed storage, when the data is dispersed to different nodes, the computation will propagate to the node where the data resides, according to the provided collocated key, and then the data is collocated and the associated data is stored in the same no
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
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 version covered in this article is 2.4.
Apache-ignite Introduction (i) 1, Introduction? Ignite is a distributed memory grid implementation, based on the Java platform, with the characteristics of persistence, distributed transactions, distributed computing, in addition to support rich key-value storage and SQL syntax (based on the H2 engine), can be seen as a distributed memory database.Products similar to ig
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
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.

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 different data sources The function of data organization management in distributed memory. in
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:
Package My.ignitestudy.datagrid;
Import Org.apache.ignite.Ignite;
Import Org.apache.ignite.IgniteCache;
Import org.apache.ignite.Ignition;
Import Org.apache.ignite.cache.CacheAtomicityMode;
Import org.apache.ignite.configuratio
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 at least active with the
For Oracle, what other monitoring tools besides EM and Gridcontrol are available? Maybe precise is also a good choice. I saw a brother in the Forum a few days ago.

Ignite distributed Computing

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

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

Recently I want to write a higher level of abstraction to more convenient training Pytorch network, inadvertently found that pytorch users under a ignite repo, curious to see what this is a thing. The original is Pytorch has provided a high-level abstract library to train the Pytorch model, since there is a wheel, then there is no need to
When writing the Ignite service, the service is typically configured in the startup file:class= "Org.apache.ignite.services.ServiceConfiguration" > class = "Com.***impl" >Classes injected in the implementation class @Autowired private ctsmgr ctsmgr; According to Spring's habit we inject interfaces usually choose @autowired or @resource,ignite is also compatible with spring.
