Solr learning Summary (7) Overall Solr search engine architecture, solr Search Engine After some efforts, I finally summarized all the solr content I know. We have discussed the installation and configuration of solr, the use of web management backend, the Query parameters

Solr learning Summary (1) Solr introduction and solr learning Summary I have been working on Solr issues recently, researching Solr optimization, and modifying search engine bugs. In the past few days, I have finally had time to summarize and share these issues for your ref

mainly used to store data, but mainly used to query stored data (a query request is a read operation ). Therefore, if you need to update data frequently, the search engine may not be suitable for your needs. Other NoSQL technologies, such as Cassandra, may be more suitable for your fast and random writing needs. Document-oriented data So far, we have been using a more general term "data", but in reality, search engines are processing document data.

Apache Cassandra is an open-source Distributed Key-value storage system. It was initially developed by Facebook to store extremely large data. Cassandra is not a database, it is a hybrid non-relational database, similar to Google's bigtable. This article mainly introduces Cassandra from the following five aspects: Cassandra's data model, installation and preparat

We now have a three-node Cassandra cluster on 192.168.129.34, 192.168.129.35, 192.168.129.39, because we have 7199 ports on each node (JMX monitor Port), So we can use Jconsole to detect the state of these nodes. Open the Jconsole under%java_home%/bin, enter 192.168.129.34:7199 in the remote connection, and then click Connect: More Wonderful content: http://www.bianceng.cnhttp://www.bianceng.cn/database/extra/ So you can go to the Jconsole interf
