Mongodb vs PostgresSQL: Compare Database Structure

On the other hand, MongoDB uses a replica set architecture, where each replica set consists of a primary node and one or more secondary nodes. The primary node receives write operations and replicates the changes to the secondary nodes. If a primary node fails, one of the secondary nodes will be elected as the new primary. It supports a variety of extensions or plugins that can be used to add new functionalities such as full-text search and GIS capabilities.

Replica sets can be implemented across various data centers too, as they would come in handy in case of regional outages. This can be done by MongoDB Atlas, which makes building and configuring these clusters simpler and quicker. You can also implement list partitioning where the table is partitioned according to the key values specified. Because PostgreSQL relies on a scale-up strategy to scale writes or data volumes, it must make the most of the computing resources available.

MongoDB, PostgreSQL, and Airbyte: Simplifying Data Integration

MongoDB and MySQL, two prominent contenders in the database landscape, cater to different use cases based on their unique strengths and capabilities. Both databases use different syntax and terminology to perform many of the same tasks. Where PostgreSQL uses rows to record data, MongoDB uses documents, etc. They also have many features that distinguish them from one another. BSON skips the keys that aren’t useful for the query, thus making it faster to retrieve data.

  • It offers a flexible, document-oriented approach to data storage and retrieval.
  • It stores data as JSON documents, making it easier for developers to store and retrieve data.
  • This statement uses the GeoJSON geographical query features of MongoDB to do that.
  • It is a well-known fact that the demand of users is changing at a very fast speed.
  • PostgreSQL database management systems possess strong support from third-party tools, both free and commercial.
  • The most recent version of PostgreSQL has new features such as improved performance for queries and performance gains and space savings when B-tree index entries become duplicated.

However, the rise of new data types and dynamic use cases led to the emergence of NoSQL databases. It allows us to use tables and columns to reduce redundancy in data, minimize anomalies in data modification, and simplify queries. Creating relational data models take time where a document database such as MongoDB can be more fluid and works well with developers. One disadvantage of PostgreSQL when compared to MongoDB is its reliance on relational data models that are unfriendly to data structures that developers use in code. They have to be defined in advance, which can delay progress as requirements fluctuate.

PostgreSQL vs. MongoDB: Features and Benefits Comparison

If you developed a project that did not change after its conception, you probably didn’t learn anything during the construction process or you didn’t care about the unexpected twists. Planning cannot completely predict all real-world problems, so be ready to adjust your decisions and beliefs along the way. First, we built an environment to replicate our data acquisition pipeline, but we did it aggressively. We created a script to simulate a data flow bigger than the current one. At the time, our throughput was around 16,000 operations per second, and we tested the database with 160,000 operations per second (so basically 10x). Airbyte pipelines can help streamline your data ecosystem by centralizing data from all related sources, databases, and applications.

MongoDB has good flexibility which makes it a good choice for consolidating data from different sources. Vertical scaling is best with PostgreSQL, where performance is enhanced by upgrading hardware or optimizing queries. PostgreSQL’s vertical scalability and focus on ACID compliance make it suitable for scenarios demanding strict data integrity mongodb postgresql and complex queries. Its performance scales well vertically with hardware upgrades, but horizontal scaling might require more intricate setup. While it supports some level of horizontal scaling, it’s not as ideal for this structure in comparison with MongoDB. MongoDB doesn’t enforce schema upfront and has an easy learning curve.

Support & Community

PostgreSQL’s design principles emphasize SQL and relational tables and allow extensibility. Both PostgreSQL and MongoDB have strong communities of developers and consultants who are ready to help. If a SQL database fits your needs, then PostgreSQL is a great choice. RestApp offers built-in MongoDB and PostgreSQL integrations that quickly connect to your account. These steps may seem simple, but keep in mind that this is a very simplified version of the actual data migration issue.

That is, we created a CNAME in DNS that, at first, pointed to the proxy’s ELB and would change to point to the API ELB. This allowed a single change to be made rather than updating each individual client of the API. To solve this, we created HTTP endpoints to change the config in memory across all instances in the load balancer instantaneously. This allowed us to very quickly switch which API was primary without needing to edit a config file and redeploy. Additionally, this could be scripted, reducing human interaction and error. The first stage of this was to change the priorities of the APIs, so that the proxy talked to Postgres first.

MongoDB: The Document Database That Has Come So Far

However, PostgreSQL’s level of security may differ from one cloud system to another, even if it’s the same database. It can be difficult to adjust the structure of the database once it’s loaded. It needs several teams in development, ops, and the database administrator to coordinate the changes made in the structure carefully. Mongo RealmDB is available free of charge to all Atlas users for evaluation and light usage, enabling developers to build and release mobile applications.

Mongoexport will not produce an error if there is no such key in the document. The developer must verify that the keys that must be present in the CSV file are defined. We’ll start by creating a CSV file from an existing Mongo collection with the mongoexport command. Fast forward to March 2018 and we had now finished migrating CODE, with no detrimental impact on performance of the API or user experience in the CMS.

Advantages and Disadvantages of mongodb vsPostgreSQL

MongoDB offers a modern selection of cybersecurity controls and integrations for both its cloud and on-site versions. This features strong security paradigms such as client-side, field-level encryption — this enables users to encrypt data before sending it to the database via the network. MongoDB makes data a lot like code, from an individual developer point of view. A developer could define a BSON or JSON document’s structure, undertake some development work on it, see how they get on with it, introduce new fields whenever they like, and rework data as required.

Like MySQL and other open source relational databases, PostgreSQL has been proven in the cauldron of demanding use cases across many industries. If data aligns with objects in application code, then it can be easily represented by documents. MongoDB is a good fit during development and in production, especially if you have to scale.

Introduction to MongoDB vs PostgreSQL

It is open to contributions or extending the code to create a database based on your requirement. You can also pay for managed PostgreSQL instances through a variety of cloud providers. MongoDB stores data as collections of documents in a flexible, JSON-like format called BSON (binary JSON). This allows you to store and retrieve data in a more flexible and scalable way, without having to conform to a rigid data schema.
