mongo express

I have been in the terminal operation of the MONGO, various update set remove INSERT, and then looked under a mongovue called the client, the interface is more convenient to operate it ~Online search, said Mongovue has been n years has not been updated.However, it is still recorded, because its configuration is somewhat interesting.A moment to downloadOfficial website: http://www.mongovue.com/downloads/Two-InstallationJust chutes next down.Three use

SQL Server has tools for database optimization. Mongo database profiler not only has but also has more powerful functions. MongoDB comes with a profiler that allows you to easily record all operations that take a long time to facilitate optimization. There are two ways to control the profiling switch and level. The first is to directly set it in the startup parameters. When MongoDB is started, add-profile =LevelYou can. You can also call dB. set

Park so long time, also should write something, recently in using node to write things, oneself is not very familiar with, how to set up the environment simply say, for reference only.I was developed under the Win7 environment.1. Install node,https://nodejs.org/download and automatically install NPM after download.2. Install the mongo,http://www.mongodb.org/downloads and configure it to boot from the service, see other blog posts.3. Install git, http:

The previous five comparisons have received positive feedback from everyone, as well as individual experts who have written me the code I write.I wrote the query method of the performance problems, I think, if MONGO is not delayed loading, then my query is really a problem, it became a query out all the data and then two times to filter.Maybe this is also the habitual use of the Entity Framework framework. Today hurriedly carried out a bit of code, no

Write to the second one has to say that I made a small mistake before, in fact, the implementation of the sub-table storage is very simple, first of all I want to achieve what kind of effect itIs that the user table has a score field, the score field is a child tableActually realizes this function is also very simple, uses the object-oriented thought to understand very well, the child table is an object field or the collection field of the user table, so I think the development of C #

Today, the main test of the query function, of course, is mainly to let the query and we usually use the entity object associated with, and those bsondocument and collection we operate is not too convenientOr first define a user class, notice that this class needs to match the field of the object in the MONGO exactly, including the case, otherwise the field cannot match the error when the query occurs Public class User { publicgetset;}

MONGO Database How do I test whether the MONGO database is connected? I just got in touch with MongoDB today. Not very familiar. Are there any learning materials in this area? Thank you! ------Solution-------------------- PHP Code Selectdb (' fish_test '); If no database is automatically created $collection = $db->selectcollection (' fish '),//If no database table is automatically cre

specifies the size of the operation log-- Opidmem Arg size limit (in bytes) for in memory storage of OP IDs specifies the memory size for storing operation logs. Sharding options:-- Configsvr declare this is a Config dB of a cluster specifies the configuration server in the shard.-- Shardsvr declare this is a shard dB of a cluster specified shard Server Usage Details: Before starting MongoDB, we must create a directory to store MongoDB data and logs. [Root @ localhost bin] #./mongod -- dbpath

Mongo file space is composed of one file space, such When MongoDB is just installed, only one specified dB has only one file space. For example, the DB here is filedb. So his first file space is filedb.0, but when the filedb.0 file space is full of files, MongoDB will allocate a file space that is twice the size of the original database. Here, filedb corresponds to filedb.1 Next, I will not apply for a larger file space until 2 GB.

Https://github.com/ewcmsfree/ewcms/wiki/Help-mongo-java-driver-date The Mongo storage date is a 64-bit integer number. When the Java driver saves the date, it will automatically convert it to the standard time GMT. For example, in GMT + 8 time zone in China, save 00:00:00 to the database. The query result is 16:00:00, which is inconsistent with the expected result. You can find the root cause of the problem

Some conceptsFor MONGO in data disaster recovery, the recommended pattern is to use replica set mode, which has an external primary server primary, and N replica server secondary (n>=1, when n=1, need to have an arbiter server arbiter when n> 1 o'clock does not require arbiter), they were previously synchronized through the internal mechanism, and when primary hung, it will be through the internal heartbeat mechanism, the election of a secondary to be

Redis vs memcached vs MONGO Redis vs memcached: Redis as a high-performance key-value database has the following characteristics: 1. A variety of data models (String, Hash, List, set, and sorted set) 2. Persistent-bgsave (using RDB snapshots, in the form of a landing instruction, fork a process to dump the entire memory onto the hard disk (fork consumes a lot of memory and IO), or use the AoF log method similar to MySQL to record each updated
