-level locks), MongoDB has brought great pain to database operators, and even some have begun to turn to tokumx, even though the latter is currently not very stable. Aware of this problem mongodb, made a rich wayward decision to directly acquire the storage engine vendor Wiredtiger, integrating the Wiredtiger storage engine into version 3.0 (available only in 64-bit editions). So what are the expected

MongoDB Series 3: MongoDB user permission operations After preliminary research on configuration and basic understanding, the following section describes MongoDB's user permission operations. Brief Introduction: Like all other databases, permission management is similar. Mongodb stores all user information in the admin

into 3 types: SQLReoverableException , SQLNonTransientException , SQLTransientException . SQLNonTransientException SQLTransientException There are several subcategories under and below that detail the various error conditions that may occur in the JDBC program. Most subclasses have a corresponding standard SQLState value, which is a good way to combine the SQL standard with the Java 6 class library.Figure

First, start the MongoDB shelltool, that is, bind the cmd.exe Common shell commands are as follows: 1. query the names of all local databases > show dbs; 2. Switch to the specified database environment (if no database is specified, a new database is created) > use dbtest; Switch to the dbtest database or create a database named dbtest.3. query all collection sets in the current database (equivalent to table

MongoDB can run on a variety of operating system platforms such as Windows, Linux, OS X, and Solaris, and deployment is simpler.MongoDB's design goals are high-performance, scalable, easy to deploy, easy to use, and easy to store data. Its main functional characteristics are as follows:(1) For collection storage, it is easy to store data of object type. In MongoDB
