In this article we'll examine the differentiators and similarities between MongoDB and Redis for the purpose of helping you to choose the option which is the best fit for the project you're working on. Make the best decision today could save you numerous headaches over the future.
MongoDB and Redis Different Storage Solutions to meet different requirements
MongoDB retains files on disks as collections comprising Binary JSON (BSON) documents as the default. The storage on disk provides greater capacity and a lower chance of system failures. The storage of data in BSON documents allows MongoDB to deal with various kinds of data formats JSON cannot recognize. In addition, it can keep data on the cloud or in memory.
Furthermore, MongoDB has no schema or a fixed structure for data and does not depend on the development of documents. It makes it simpler to users who aren't experienced with the database and makes it faster in processing large amounts of data for long periods of time.
MongoDB is a superior scaler with a broad range of vertical, horizontal and flexible options. It is adjustable to the future and is an an ideal choice for business owners or those who need to prepare for changes in the future and expand.
If your undertaking is characterized by a significant amount of change in data, Redis is the better alternative. Redis's flexibility Redis is a result of its ability to be capable of storing data in key/value format that is able to manage a wide range kinds of data. Redis is also able to perform the function of an intermediary between messages and cache.
Database Architecture
The database's structure can be used to determine criteria to collect, store and access data, as well as the integration and enhancement of data within an individual managing system for databases. Understanding the structure of a database is crucial as it determines the efficiency of the database and also the capability that the database can provide.
However, Redis relies heavily on key/value stores that store the information within a certain collection that has two components which are key and an amount it has assigned. Redis uses a unique identification number (a key) for storing and accessing certain details. Keys are stored in a dictionary and they require a parser for it to process a variety of different values (because every key is capable of only storing one value as of the default).
Redis can also support various types of data structures in addition to values such as hashes strings, sets, hashes along with lists streams, sets, geospatial indexes as well as bitmaps. But their capacity for storage is limited by the storage capacity of RAM storage, and the data stored isn't that easy to grow and retrieve as time progresses.
MongoDB and Redis the key differences
Here is the table that provides the key aspects and the differences between MongoDB Redis and MongoDB. Redis:
| HTML1 MongoDB | Redis | |
| Speed | Schema-less architectures allow for higher speeds to store huge quantities of data need to be saved on disk. | It's much faster than MongoDB for the case that large amounts of data needs to be stored in its memory storage. |
| Scalability |
The built-in sharding feature allows scaling across a variety of geographic zones and also nodes.
Sharding using hashed, range sharding, zone sharding, and cross-sharding are all possible. Backups of a trusted cloud are accessible using MongoDB Atlas. Multiple languages are offered for the majority of community drivers as well as official drivers. |
Redis clusters are scalable.
Hashed Sharding by itself. Shards are kept in a manual manner. There is no consistent data between the shard backups. Driver support isn't as comprehensive. |
| Transactional Security of Data | Multi-document ACID transactions can be supported by the syntax of multi-statement. |
Multi-record and multi-command aid.
No default rollbacks support. |
| Memory Utilization | On-disk storage. It consumes a significant amount of memory. 1 GB per 100,000 assets. |
In-memory storage. It's expected to use around 4GB of RAM.
A higher memory usage that MongoDB. |
| Indexes Indexes |
Index construction is easy and wide.
MongoDB Atlas Performance Advisor will give users access to new indexes. Secondary indexes can easily be employed to develop applications to process data in various methods. |
Secondary indexes are not easily developed and managed manually. |
| High Access | High-availability via replication. | High availability through primary-secondary replication over many nodes and centres. |
| query Language |
MongoDB MySQL API queries that include text searches, ranges as well as single or multi keys.
It generates materialized copies of the data it has retrieved (on request) as well as geospatial queries and graph traversals. |
Key-value queries alone. Lower query features are further enhanced by the addition of Redis modules. |
| Persistent Store | Persistent volume feature in Kubernetes achieves data/storage persistence. | Append-Only File Persistence for Data and Snapshot aid in the persistence of data storage. |
| An aggregate of data |
Map reduce functions along with an aggregation pipeline may be used to facilitate the aggregation of data.
MongoDB Atlas makes use of the builder of pipelines to construct and maintain pipelines to facilitate the aggregate. |
Map Reduce function, as well as pipelines for the aggregation of data are used. |
MongoDB vs Redis: Ideal Usages
It's important to consider the specifications in a way of making a decision between two technology picking the appropriate database for you most strongly will depend on the project you're working on.
If speed and minimal latency are the deciding aspects to you, Redis is a good choice for achieving the highest performance. Redis is able to meet the requirements of a variety of software, such as fraud detection and modern game development, which require huge amounts of constantly evolving, instantaneous data efficiently and rapidly.
Redis using
This could improve the efficiency of your WordPress projects due to the permanent archive of information created by WordPress's natural object cache. The permanent storage allows the projects to use cached objects without having to call the MySQL database multiple times (or even) in order to find the specific object. This reduces the amount of time needed to respond to a website's online presence as well as the load on the MySQL database, as well as increasing the capability to handle the information.
Summary
MongoDB and Redis are excellent databases to manage your project. Their distinct storage requirements, structure, model and features make it obvious that your selection will depend on the specific requirements of your specific project.
MongoDB is stable and reliable suitable for general-purpose projects. However, its storage model based on disks is slow for handling real-time data.
However, Redis' in-memory storage allows it to be much more adept in handling huge amounts of information in real-time. But, it doesn't have the same performance, and is more suitable for developers who are just beginning their careers.
Redis add-on Redis extension of Redis is easy to integrate Redis into your project without worry about how to manage the application. Additionally, it increases the efficiency of your project by directing your efforts on more crucial business issues.
