MySQL and sell the two software as an integrated tool. If they want to bind MySQL with their own code, or if they think it is necessary to do so, they need to continue purchasing a commercial license. MySQL and NoSQL Oracle databases must be smart enough to recognize that they have limited requirements before users start to rewrite their own code. For example, Twitter has announced that it will migrate its infrastructure to Cassandra, another open so

Elasticsearch uses Lucene to perform its indexing function at the bottom, so many of its basic concepts originate from Lucene.3. cassandra--Open source distributed database management system, originally

Since its inception in 1999, the Apache Software Foundation is now home to a number of important open source software projects. Among the successful projects are Geronimo, Tomcat, Hadoop and a distributed computing system that is now the key hub of the big Data kingdom.Although Apache does not maintain complete statistics on downloads, like Apache HTTP Server, which has become an engine for nearly 500 million sites worldwide, such as OpenOffice, it has been downloaded millions of times, although

more than 30 years of good alternatives. In general, these alternatives have been called "NoSQL databases." ” The fundamental problem is that the relational database cannot handle many modern workloads. There are three specific questions: expand to (3TB Green badge) or Facebook (search in 50TB Inbox) or ebay (whole 2PB) to the website like the Digg News review site, Per-server performance and rigorous architecture design.

The following article mainly introduces why Digg uses NoSQL to replace MySQL databases. Although MySQL databases are widely used, they also have some disadvantages, for example, the actual operation in Digg is not as flexible as that in NoSQL. The following describes the main content. Following Twitter, Digg, a social media news website, decided to say goodbye to MySQL and replace most of its infrastructure components. Digg will go from LAMPLinux, Apache, MySQL and Perl/PHP/Python) the architec

Krist ófskács, a software architect and consultant who once worked in a number of major companies, blogs on mainstream NoSQL databases (Cassandra, Mongodb, CouchDB, Redis, Riak, Membase, Neo4j, and HBase)) A comprehensive comparison was conducted. Although SQL database is a very useful tool, after 15 years of outstanding performance, the monopoly will be broken. This is only a matter of time: I was forced to use relational databases, but I finally fou
