Horizontal scaling means that each shard in every cluster houses a portion of the dataset in question, essentially functioning as a separate database. Combining the data of the distributed shards forms a single, comprehensive database much better suited to handling the needs of a popular, growing application with zero downtime. The MongoDB database platform has been downloaded over 200 million times with over 1.8 million MongoDB University registrations. There are drivers for 10+ languages, with dozens more added by the community. MongoDB supports multiple storage engines, such as WiredTiger Storage Engine and MMAPv1 Storage Engine.

MongoDB Key Features

DBKoda offers multiple features that improve user productivity, including a real-time view of activity, a storage analyzer, MongoDB commands convertible to Node.js syntax, and more. It provides users with a MongoDB schema graphical view and analysis of documents within an intuitive GUI. With it, users can easily manage their databases by writing, editing, and executing postgresql has many modern features including code. Robo 3T’s embedment of the JavaScript engine that powers MongoDB’s mongo shell is one of its standout features. This allows you to do everything in Robo 3T that you could do in the mongo shell. With the exponentially growing semi-structured and unstructured data on the web, it becomes essential for businesses to look out for a robust database management system.

Studio 3T (formerly MongoChef) – Professional Client, IDE, and GUI for MongoDB

MMS is a powerful web tool that allows us tracking our databases and our machines and also backing up our data. MMS also tracks hardware metrics for managing a MongoDB deployment. It shows performance in a rich web console to help you optimize your deployment. It also provides features of custom alerts which helps to discover issues before your MongoDB instance will be affected.

Documents consist of key-value pairs which are the basic unit of data in MongoDB. Collections contain sets of documents and function https://globalcloudteam.com/ which is the equivalent of relational database tables. MongoDB is a database which came into light around the mid-2000s.

MongoDB is such a NoSQL database that scales by adding more and more servers and increases productivity with its flexible document model. MongoDB, the most popular NoSQL database, is an open-source document-oriented database. It means that MongoDB isn’t based on the table-like relational database structure but provides an altogether different mechanism for storage and retrieval of data. MongoDB is flexible and does not need the data to be normalized first.

If you’re looking for a MongoDB GUI, TablePlus is an excellent option. It’s a powerful and easy-to-use MongoDB client that makes working with your database easier than ever. Not to mention, it has a few other features that make it even handier, like an integrated MongoDB IDE.

Each database gets its own set of files on the file system. MongoDB is a document database, which means that it stores data in the form of “objects” which have properties that can be changed, added to, deleted, and queried against. While in an academic sense, MongoDB stores values for keys , it would be a bit of a simplification to call MongoDB simply a key-value database .

The aggregation framework enables users to obtain the kind of results for which the SQL GROUP BY clause is used. This MapReduce can be used to parallelize, allow huge data for processing over lots of cores/machines. NoSQLBooster provides an all-inclusive GUI for MongoDB, complete with SQL query support, script debugger, server monitoring, and true IntelliSense.

Ad-Hoc Queries

The ability of MongoDB to efficiently store flexible schema documents and perform an index on any of the additional fields for random seeks makes it a compelling key-value store. Without the right indexes, a database is forced to scan documents one by one to identify the ones that match the query statement. But if an appropriate index exists for each query, user requests can be optimally executed by the server. MongoDB offers a broad range of indexes and features with language-specific sort orders that support complex access patterns to datasets. A primary server or node accepts all write operations and applies those same operations across secondary servers, replicating the data.

At the end of the day, optimal load balancing remains one of the holy grails of large-scale database management for growing enterprise applications. Properly distributing millions of client requests to hundreds or thousands of servers can lead to a noticeable difference in performance. In our experience, the number one issue that many technical support teams fail to address with their users is indexing. Done right, indexes are intended to improve search speed and performance. A failure to properly define appropriate indexes can and usually will lead to a myriad of accessibility issues, such as problems with query execution and load balancing.

  • The MongoDB database platform has been downloaded over 200 million times with over 1.8 million MongoDB University registrations.
  • Documents consist of key-value pairs which are the basic unit of data in MongoDB.
  • MongoDB, the most popular NoSQL database, is an open-source document-oriented database.
  • Having said that, wild card indexing should only be used in use cases when we cannot predict the field names upfront and the variety of the queries predicates require so.
  • When one of the set members can’t reach the primary instance for more than 10 seconds, the replica set will automatically elect and promote a secondary instance as the new primary.

Wild card indexing allows users to index every field or a subset of fields in a MongoDB collection. MongoDB is open-source, is one the highest performing database. With the implementation of replication and indexing, query execution and data fetching are faster. With developing multiple applications, the need to check the performance is mandatory. Database Profiling, which collects the complete data for every operation that is executed against the MongoDB instance. The output provided by the DB Profiler can help us understand the queries and operations that are being inefficient.

High Performance

Try MongoDB Atlas as your key-value database and reveal new possibilities to innovate your applications. A key-value approach allows defining efficient and compact data structure to access data in a simple form of a key-value fetch/update/remove. Real time random data access, e.g., user session attributes in an online application such as gaming or finance. Indexes support faster queries and can include keys from embedded documents and arrays.

MongoDB Key Features

Embedded documents and arrays reduce need for expensive joins. Let’s take a look at some of the most essential technical features of MongoDB. MongoDB provides developers with a number of useful out-of-the-box capabilities, whether you need to run privately on site or in the public cloud.

What is a key-value database?

Having said that, wild card indexing should only be used in use cases when we cannot predict the field names upfront and the variety of the queries predicates require so. It is built with security in mind, and has multiple features for authentication, authorization, and encryption. All data transfers use SSL/TLS to ensure that your data is transmitted between the clients and the server in the most secure way possible. In addition to encryption across the wire, data can automatically be encrypted on the client before leaving the application. This can be useful when working with sensitive user information.

Each shard holds a portion of the data and functions as a separate database. The collection of several shards together is what forms a single logical database. The operations are performed through services called query routers, App server and configuration servers which decide which operation needs to be routed to which shard.

What’s called Table in RDBMS is called a Collection in MongoDB. Similarly, a Tuple is called a Document and A Column is called a Field. MongoDB provides a default ‘_id’ which is a 12-byte hexadecimal number that assures the uniqueness of every document. Indexing – Indexes can be created to improve the performance of searches within MongoDB. Just a quick note on the key difference between the _id field and a normal collection field. The _id field is used to uniquely identify the documents in a collection and is automatically added by MongoDB when the collection is created.

Robo 3T is the best GUI application if you are a beginner and want something with a supportive community. However, Studio 3T would be better suited for those who are experienced and looking for an upgrade from Robo 3T. MongoDB is Enterprise certified and supports LDAP, Kerberos, and MONGODB-X509 authentications.

The most common is the Salted Challenge Response Authentication Mechanism , which is the default. When used, SCRAM requires the user to provide an authentication database, username, and password. MongoDB supports fixed-size collections called capped collections. Once the specified size has been reached, it starts behaving like a circular queue. MongoDB is a schema-less database (written in C++) because of which is much more flexible than traditional database tables. The benefit is the lack of setup and the reduced friction with OOP.

These chunks have a size of 255KB, excluding the last chunk. GridFS, which stands for Grid File System, use two separate collections. One collection is used to store the larger file’s chunks, while the second collection is used to store the metadata. When we execute a query for this file, the GridFS will collect and return all the chunks together. GridFS also implements the Indexing, which allows the query execution for returning the file easier.
