registering PDX type in type registry with Geode C# native client

由 一个人想着一个人 提交于 2019-12-11 15:08:37
问题 I am trying to implement a very simple PDX autoserialization in Geode. I've created a domain class of my own with a zero arg constructor: public class TestPdx { public string Test1 { get; set; } public string Test2 { get; set; } public string Test3 { get; set; } public TestPdx() { } } Now I want this class to auto serialize. I start a server cache with the following cache.xml where I attempt to register this type for auto PDX: <?xml version="1.0" encoding="UTF-8"?> <cache xmlns:xsi="http:/

minimal test with apache geode

由 风流意气都作罢 提交于 2019-12-11 09:41:59
问题 I would like to extend geode with custom binary data (serialization). Is there any documentation about how to kickoff a minimal setup/system using geode? I saw a docker image but didn't find any docs on this. It would be more than enough for me to have a c++ client which can push and query the stored (~30 GB of) data by a key. Thank you very much for your help! 回答1: Checkout... https://cwiki.apache.org/confluence/display/GEODE/Index#Index-Geodein5minutes There is more information on the Geode

Geode native client deserialise PdxInstanceImpl

由 若如初见. 提交于 2019-12-11 00:16:05
问题 I have a REST client that populates a Geode region with Json data which the Geode REST API automatically converts to a PdxInstance type. The region triggers a C# native client listener AfterCreate(EntryEvent<TKey, TVal> ev) in which the TVal type ev.NewValue is seen as type PdxInstanceImpl and looks like: PDX[7534066,__GEMFIRE_JSON]{@type=MyClass, Field1=Value1, Field2=Value2} I've seen from here that the following code can get at the individual Pdx fields IPdxInstance pdx = (IPdxInstance)ev

How do I set the Hibernate dialect in SpringBoot?

由 三世轮回 提交于 2019-12-10 12:46:55
问题 I have a custom dialect to set for Hibernate in SpringBoot. The dialect is for Gemfire. The instructions (https://discuss.zendesk.com/hc/en-us/articles/201724017-Pivotal-GemFire-XD-Hibernate-Dialect) are for XML-based config. However, I am using SpringBoot and I cannot figure out how to set this property. The dialect is "com.pivotal.gemfirexd.hibernate.GemFireXDDialect" 回答1: In application.properties spring.jpa.properties.hibernate.dialect = com.pivotal.gemfirexd.hibernate.GemFireXDDialect

1.Ignite简介 Apache Ignite 内存数据组织框架是一个高性能、集成化和分布式的内存计算和事务平台，用于大规模的数据集处理，比传统的基于磁盘或闪存的技术具有更高的性能，同时他还为应用和不同的数据源之间提供高性能、分布式内存中数据组织管理的功能。 2.Ignite历史 Ignite来源于尼基塔·伊万诺夫于2007年创建的GridGain系统公司开发的GridGain软件，尼基塔领导公司开发了领先的分布式内存片内数据处理技术-领先的Java内存片内计算平台，今天在全世界每10秒它就会启动运行一次。他有超过20年的软件应用开发经验，创建了HPC和中间件平台，并在一些创业公司和知名企业都做出过贡献，包括Adaptec, Visa和BEA Systems。尼基塔也是使用Java技术作为服务器端开发应用的先驱者，1996年他在为欧洲大型系统做集成工作时他就进行了相关实践。 2014年3月，GridGain公司将该软件90%以上的功能和代码开源，仅在商业版中保留了高端企业级功能，如安全性，数据中心复制，先进的管理和监控等。2015年1月，GridGain通过Apache 2.0许可进入Apache的孵化器进行孵化，很快就于8月25日毕业并且成为Apache的顶级项目，9月28日即发布了1.4.0版，2016年1月初发布了1.5.0版，应该说发展、迭代速度非常快。该技术相关资料较少
