问题 I am trying to apply patch LUCENE-2899.patch to Solr. I have done this: Cloned solr from official repo (I am on master branch) Downloaded and installed ant and GNU patch, i get it here http://gnuwin32.sourceforge.net/packages/patch.htm Put Ant and GNU patch to PATH env var. And I got this... ``` D:\utils\solr_master\lucene-solr>patch -p1 -i LUCENE-2899.patch --dry-run patching file dev-tools/idea/.idea/ant.xml Assertion failed: hunk, file ../patch-2.5.9-src/patch.c, line 354 This application

SolrCloud wiki翻译(6)近实时搜索, 索引复制,灾难恢复

SolrCloud and Replication SolrCloud与索引复制 Replication ensures redundancy for your data, and enables you to send an update request to any node in the shard. If that node is a replica, it will forward the request to the leader, which then forwards it to all existing replicas, using versioning to make sure every replica has the most up-to-date version. This architecture enables you to be certain that your data can be recovered in the event of a disaster, even if you are using Near Real Time searching. 索引复制确保为你的数据提供了冗余,并且你可以把一个更新请求发送到shard里面的任意一个节点。如果收到请求的节点是replica节点,它会把请求转发给leader节点

solrcloud Recovery原理及无法选举分片leader

妖精的绣舞 提交于 2019-12-02 21:13:42
我们在使用SolrCloud中会经常发现会有备份的shard出现状态Recoverying,这就表明SolrCloud的数据存在着不一致性,需要进行Recovery,这个时候的SolrCloud建索引是不会写入索引文件中的(每个shard接受到update后写入自己的ulog中)。 1、solrcloud Recovery原理 1.1、Recovery原因 SolrCloud启动的时候,主要由于在建索引的时候发生意外关闭,导致一些replicat的数据与leader不一致,那么在启动的时候刚起的replicat就会从leader那里同步数据。 SolrCloud在进行leader选举中出现错误,一般出现在leader宕机引起replicat进行选举成leader过程中。 SolrCloud在进行update时候,由于某种原因leader转发update至replicat没有成功,会迫使replicat进行recoverying进行数据同步。 1.2、Recovery原理 着重介绍第三种情况的recovery 在solrcloud接受写入的过程中,不管update请求发送到哪个shard 分片中,最后在solrcloud里面进行分发的顺序都是从Leader发往Replica。Leader接受到update请求后先将document放入自己的索引文件以及update写入ulog中

SolrCloud Wiki翻译(3)Shards & Indexing Data

本小妞迷上赌 提交于 2019-12-02 21:13:28
When your data is too large for one node, you can break it up and store it in sections by creating one or more shards . Each is a portion of the logical index, or core, and it's the set of all nodes containing that section of the index. 当你的数据放在一个节点上显得太臃肿的时候,你可以通过创建一个或者多个shard把他们分割开并且存储到这多个shard中。每一个shard都是逻辑索引或者说是core的一部分,并且它是包含了指定分段索引的所有节点的一个集合。 A shard is a way of splitting a core over a number of "servers", or nodes. For example, you might have a shard for data that represents each state, or different categories that are likely to be searched independently, but are often combined.

How to do Solr Dataimport (i.e from RDBMS) using Java API?

问题 I am new to Solr, actually I tried Database table indexing in Solr manually, i.e creating a new data-config.xml and running the full import from Solr webUI, successfully did that. But now I need to do the same thing in Java. So I need know the following things using Java: How to set Solr datasource in Java api How to set the entity and query How to run full import Actually, for data import we write a configuration file like below <?xml version="1.0" encoding="UTF-8" ?> <dataConfig>

学习主题:商品数据检索 1.Solr集群_SolrCloud环境搭建_数据导入 (1)谈谈对象SolrCloud的理解,SolrCloud进行数据写入的工作过程。 SolrCloud(solr 云)是 Solr 提供的分布式搜索方案,当你需要大规模,容错,分布式索引和 检索能力时使用 SolrCloud。当一个系统的索引数据量少的时候是不需要使用 SolrCloud 的, 当索引量很大,搜索请求并发很高,这时需要使用 SolrCloud 满足这些需求 (2)谈谈SolrCloud和Zookeeper集群的关系 SolrCloud 不同于 redis 集群自带集群,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 2.实现商品信息关键字检索_分页_高亮显示 (1)描述Solr实现高亮显示的步骤 SearchItemServiceImpl: package com .bjsxt.ego.search.service.impl ; import com .bjsxt.ego.rpc.pojo.TbItem ; import com .bjsxt.ego.rpc.service.ItemService ; import com .bjsxt.ego.search.dao.ItemDao ;
