How to remove all the duplicate results in Hibernate Search?

问题 I'm using Infinispan with 6.0.2 with Hibernate Search 4.4.0. In the begining, after I execute a query like CacheQuery cq = SearchManager.getQuery(query,Hibernate.class).projection("id"); I use the cq.list() to get "id". But now the number of results reaches 300.000, because of the designing fo DB(cant change), the duplicate id is almost 29,000. I wrote this to get "id": for(int i=0;i<listObject.size();i++) { Object[] rdf = (Object[])listObject.get(i); if(!result.contains((String) rdf[0]))

How can I cluster application-scope state in wildfly?

问题 I would like to cluster a map that is kept on application-level scope. A first thought was to use a @Singleton , @Clustered bean with a field holding my data. This does not seem to work and my guess is that it was never implemented This post proposes ways to implement clustered singletons but they seem complex. The only alternative that I see, apart from manually updating db table(s), is to use a replicated cache. My question is: Is it advised to declare and use an infinispan cache (like this

Keycloak(Wildfly/Infinispan) in HA mode - issue in detecting other machines in the cluster

问题 As a result, when I put the machines under an ELB, the login doesn't work. I have tried TCP and UDP for IP casting. Tried using TCPPING instead of MPING (although not sure whether I used them correctly). Infinispan is being used for distributed caching. Here is the default configuration, followed by the changes I had made: <subsystem xmlns="urn:jboss:domain:jgroups:7.0"> <channels default="tcp"> <channel name="ee" stack="udp" cluster="ejb"/> </channels> <stacks> <stack name="udp"> <transport

keycloak集群化的思考

由 浪子不回头ぞ 提交于 2021-01-13 17:49:57
简介 单体服务如果想要突破到高并发服务就需要升级为集群服务。同时集群化也为高可用打下了坚实的基础。纵观现在比较流行的服务或者中间件，不管是RabbitMQ还是redis都提供了集群的功能。 作为硬核工业代表的wildfly也不例外，最近研究了一下keycloak的集群,发现它的底层服务器用的也是wildfly,本文将会和大家探讨一下keycloak的集群的架构思路。 keycloak中的集群 我们知道，keycloak中有两种模式，一种叫做Standalone,一种叫做domain。 这两种模式的区别只是在于部署文件是否被集中管理，如果部署文件需要一个一个的手动拷贝，那么就是standalone模式。如果是一键化的自动安装，那么就是domain模式。 standalone模式下有一个配置文件叫做 /standalone/configuration/standalone-ha.xml，这个就是在standalone模式下配置集群的xml文件了。 而domain模式下，配置文件都是在domain controller这个机子上进行配置的，具体的文件是 domain/configuration/domain.xml 。 我们看下ha具体是用的集群相关的组件： <profile name="full-ha"> ... <subsystem xmlns="urn:jboss:domain
