Apache Ignite zone(rack)-aware parititons

由 独自空忆成欢 提交于 2020-04-30 09:09:30
问题 I'm battling to configure Apache Ignite to distribute partitions in zone-aware manner. I have Ignite 2.8.0 with 4 nodes running as StatefulSet pods in GKE 1.14 split in two zones. I followed the guide, and the example: Propagated zone names into pod under AVAILABILITY_ZONE env var. Then using Web-Console I verified that this env var was loaded correctly for each node. I setup cache template in node XML config as in the below and created a cache from it using GET /ignite?cmd=getorcreate

由 梦想的初衷 提交于 2020-03-04 18:55:31
问题 I am stuck on creating user with full privileges. I have created a user with name shubh. but dont know how to grant all privileges. And want to drop the default user (user = ignite , password = ignite) privileges. Please suggest. 回答1: Have you tried the following: DROP USER "ignite"; As for privileges, we don't have granular permissions in Apache Ignite yet, so if you have user it can access all tables. 回答2: So guys from the above reply's I came to the conclusion . Just change the password

Apache Ignite事务架构：第三方持久化的事务处理

由 早过忘川 提交于 2020-02-29 08:07:08
本文是Ignite事务架构系列的最后一篇文章，在之前的文章中，讨论了与键值API的事务处理有关的一系列主题。 第一篇文章 中，主要介绍了二阶段提交协议及其工作方式； 第二篇文章 中，介绍了锁模型和隔离级别，介绍了悲观锁和乐观锁中不同隔离级别对应的消息流的细节，还介绍了死锁检测机制； 第三篇文章 中，介绍了故障和恢复机制，介绍了Ignite如何管理备份节点故障、主节点故障以及事务协调器节点故障； 第四篇文章 中，聚焦于原生持久化的事务处理，其中着重介绍了预写日志（WAL）和检查点； 在最后一部分，会聚焦于Ignite如何处理第三方持久化的事务。 通读和通写 Ignite的两个主要优势是扩展性和性能。Ignite遵循的一个基本原则是不撕裂不替换，换句话说，组织中的已有系统，正在支撑关键的业务且无法被轻易替换，但是可以通过更高的扩展性和性能来增强很多的业务查询，比如，Ignite可以提供内存数据网格服务（IMDG）或者在开启通读（当缓存中不存在时数据会从数据库中加载到IMDG）和通写（数据写入IMDG时也会持久化到数据库系统）时，为第三方数据库提供分布式缓存服务，如图1所示： 但是，事务必须妥善地处理，因为数据更新跨越了Ignite和第三方存储，维护IMDG和数据库之间的数据一致性就变得非常重要，为了达到这个目标，Ignite提供了CacheStore接口

Apache ignite as shared drive for storing and retrieve files

由 孤人 提交于 2020-02-06 07:28:45
问题 My requirement is to take out the shared drive across our web application and handle file sharing using Apache Ignite (kind of file sharing service). In that way we don't need to worry about whether that shared drive is accessible and also it is seemless across applications. What do you guys suggest? Many thanks 回答1: The only relevant part of Apache Ignite was IGFS , and we have recently discontinued it. I recommend using something dedicated for file sharing. 来源： https://stackoverflow.com

Integrating apache ignite in legacy java sql based project joins issue

问题 I have a legacy java project where I have more than 1000 table and a lot of SQL queries. In order to achieve a better querying performance I m studying the apache ignite in memory database where I wan't to use the 3rd party persistence mechanism, the later is based on caching (CacheStore) that I implemented successfully in my POC, unfortunately I have lot of complex queries with lot of joins, in this case I have to update my queries using cache store names as in the example private static
