How atomic or partial update work?

由 杀马特。学长 韩版系。学妹 提交于 2021-02-10 20:39:34
问题 Solr provide feature to update document partially and it allows to update on a field level rather than on a document level. Does solr internally fetch entire document and full reindex it? would be great if someone can explain how partial update works internally? 回答1: Starting from solr 4, Solr allows updating partial documents. You can update the value of a field(s) or add/remove values from a multi valued field. The best practice while using the partial updates or atomic updates in solr is,

inter-Solr-node communication with SSL

由 假装没事ソ 提交于 2021-01-29 05:54:06
问题 Again, I have some problems with Solr. I'm trying to set up a SolrCloud cluster with three ZooKeeper instances and two Solr instances. Communication should be secured with SSL. I used the official Solr wiki as manual: https://cwiki.apache.org/confluence/display/solr/Enabling+SSL When I start the first Solr node everything works fine. I can access the Web UI via HTTP S and communication between Solr and ZooKeeper also works. But when I start the second Solr node in my cluster I get the

Autoscaling solr - Add pull replicas, not NRT replicas

由 ＊爱你＆永不变心＊ 提交于 2021-01-28 11:22:04
问题 I have a specific requirement where I just want to create only pull replicas using the solr autoscaling feature whenever the cluster starts the recovey process after a node failure. However Using solrcloud autoscaling creates NRT type replicas when node goes down and brought up. I have gone through the examples given in the policy specifcation list : https://lucene.apache.org/solr/guide/7_4/solrcloud-autoscaling-policy-preferences.html#policy-specification but I am not able to find a example

Is there a SolrJ query builder?

由 ◇◆丶佛笑我妖孽 提交于 2020-04-10 02:53:41
问题 Using solr 5.2.0 was wondering is there a query builder API/Jar/Ckient similar to Elasticsearch query builder API or do we have to bassically do String Kungfu to build queries in Solr? 回答1: Unfortunately, in SolrJ there is no such thing as a Builder for the query that goes into the q -Parameter. BUT: As Solr already operates on Lucene, we can as well use the Lucene QueryBuilder. The resulting Query objects (e.g. PhraseQuery) have a toString() method that provides you with the query string you

solrcolud安装 solrCloud+tomcat+zookeeper部署 转载请出自出处： http://eksliang.iteye.com/blog/2107002 http://eksliang.iteye.com/ 概述： SolrCloud 是基于Solr和Zookeeper的分布式搜索方案，它的主要思想是使用Zookeeper作为集群的配置信息中心。 它有几个特色功能： 1）集中式的配置信息 2）自动容错 3）近实时搜索 4）查询时自动负载均衡 安装zookeeper 上面也说了 SolrCloud 是基于Solr和Zookeeper的分布式搜索方案，所有要部署solrCloud+tomcat+zookeeper的集群，必须先安装zookeeper 安装环境： Liux: CentOS release 6.4 JDK:1.7.0_55 因为我研究的是solr最新的版本，所以研究的是solr4.8.0然后solr4.8.0必须跑在jdk1.7以上的版本 1、zookeeper是个什么玩意？ 答：顾名思义zookeeper就是动物园管理员，他是用来管hadoop（大象）、Hive(蜜蜂)、pig(小猪)的管理员， Apache Hbase和 Apache Solr 的分布式集群都用到了zookeeper；Zookeeper:是一个分布式的、开源的程序协调服务

问题 I have been trying to implement a SolrCloud, and everything works fine until I try to create a collection with 6 shards.
