MongoDB adds elements to the document model and the query engine to handle both geospatial and time series tagging of data. This expands the type of queries and analytics that can be performed on a database. Moreover, MongoDB even allows sharding, columnar compression, densification, and gap-filling for time series collections, which makes it easier to work with time series even when there are missing data points. But often at the beginning of a development project, the project leaders have a good grasp of the use case, but don’t really have clarity about the specific application features their business and users will need.
If you’d like to support me as a writer, consider signing up to become a Medium member. MongoDB uses sharding, read scalability, and automatic data balancing to offer horizontal scalability. It has a strong open-source community with lots of PostgreSQL support libraries, tools, extensions, and general support available. MongoDB organizes each document into collections, with each having a unique ObjectId, which you use to identify a document.

Factors that Drive the MongoDB vs PostgreSQL Decision
However, as data is stored in key-value pairs in one record, it lacks the security boasted by PostgreSQL; MongoDB’s main focus remains on speed. Since MongoDB 4.4, queries implemented against replica sets produce improved and predictable performance through “hedged” reads. These reads are directed to multiple nodes within the replica set until the fastest node replies. Quite often, at the beginning of a development project, project leaders have a good grasp of the use case but don’t have clarity regarding the specific application features their users and business would need.
If you already have a data model that is not going to change much, then PostgreSQL would be the best option. Efficient query execution in both systems is supported using indexing. In PostgreSQL, indexing allows the database server to find and retrieve specific rows much faster as it have to “walk” a few levels deep into a search tree. Query Q7i returns the haversine distance while Q8i returns the average speed for different amount of vessels and timestamps. The average response time is reduced in case of PostgreSQL for both queries and as the sample grows the difference begins to become more noticeable.
MongoDB vs PostgreSQL: Which is more suitable for your project in 2023?
Moreover, we are also offering MongoDB & PostgreSQL database development services. With the evolution of technology, various databases are in concept now, and MongoDB is one of them. Here, it shows that PostgreSQL can recover the application postgresql document database from failure in a structured format. Hence PostgreSQL further eases the life of a programmer because data remains in the right state always. Also, at Linearloop we have a PostgreSQL database server to develop projects without any hurdles.
Logical replication selectively replicates specific tables or subsets of data. Streaming replication creates standby replicas that receive changes in the primary database. Additionally, PostgreSQL uses the PostgreSQL Automatic Failover (PAF) to allocate a new primary if there’s a failure event. The upsides of SQL include the vast ecosystem of tools, integrations, and programming languages built to use SQL databases.
MongoDB vs PostgreSQL: Architecture
MongoDB is scalable because of partitioning data across instances within the cluster. It doesn’t split the documents into pieces as they are independent units making it easier to distribute them across various servers while data is locally preserved. Since there are no tables in MongoDB, there are no foreign keys in MongoDB either; hence no foreign key constraints. However, MongoDB does have a DBRef standard which helps standardize the creation of the references. MongoDB supports complete isolation while a document is being updated. Any errors would trigger the update operation to roll back, reversing the change and ensuring that the clients get a consistent view of the document.
However, firstly we should understand each of the databases individually and afterward, will summarize their differences. Low-code ETL with 220+ data transformations to prepare your data for insights and reporting. Another example of the difference in terminology and syntax between the two is that MongoDB uses documents to obtain data while Postgres uses rows for the same purpose. Our no-code data pipeline platform comes with out-of-the-box connectors for both MongoDB vs. PostgreSQL, helping you unify your data and gain more meaningful insights from your data warehouse.
MongoDB Vs PostgreSQL: A comparative study on performance aspects
The simplest way to perform this query is to use ST_DWithin with the PostGIS geography type, instead of geometry. The geography type is intended to be used with latitude/longitude coordinates on the earth’s surface, and performs accurate spheroid distance calculations in meters. This solution performed better because takes advantage of PostGIS’ support for GEOS prepared geometries. Second solution proved to be 3,6 times faster comparing to the well-known ST_DWithin function. In the following queries, the purpose is to measure the impact of the number of vessels in each system’s performance. Thus, we repeated a class of experiments for a set of (10, 100, 1000) vessels.
- MongoDB provides driver support for some of the best database languages like Python, R, Java, Scala, C, C++, C#, Node.js, and many more.
- It retains data using traditional syntax and schema for SQL databases.
- Postgres has been around longer and is included free of charge in many Linux operating systems, so it’s well established.
- There are challenges in managing and querying the massive scale of spatial data such as the high computation complexity of spatial queries and the efficient handling the big data nature of them.
The BSON is translated to JSON to be read when you open your collection. When viewing documents, you will recognize the ever popular JSON format with key/value pairs that is language agnostic. PostgreSQL is completely open-source and supported by its community, which strengthens it as a complete ecosystem. MongoDB has tried to solve this by introducing multi-dimensional data types where you can embed one document store inside another. However, it’s disorganized and not as elegant as the simple join function that PostgreSQL incorporates. Normalization is the process of structuring a relational database to reduce data redundancy, minimize anomalies in data modification, and improve data integrity.
PostgreSQL: The SQL Database Of Today
This also means that a database can also be scaled as much as the machine it is running on. PostgreSQL can manage a range of transactions at once and can manage data for a range of applications, from web apps to data warehouses. BSON also allows a variety of data types that are not allowed with regular JSON, such as floating-point, date, etc. MongoDB supports a range of storage engines and provides pluggable storage engine APIs allowing third parties to develop their storage engines in MongoDB. I then start some to simulate various scenarios such as importing large amounts of data, storing and querying relational as well as non-relational data and full text search.
The majority of changes in schema require a migration procedure capable of taking the database offline or reducing the performance of an application while it’s not running. BSON boasts data types that are unavailable in JSON data, such as int, datetime, decimal128, and more. It provides type-strict handling for a variety of numeric types, rather than a universal “number” type.
MongoDB vs PostgreSQL: What to consider when choosing a database
Sharding implies that the data is stored across multiple computers while partitioning groups this data within a single database instance. On the other hand, PostgreSQL supports foreign keys as it’s SQL-compliant. By enabling foreign key constraints, PostgreSQL can stop the insertion of invalid data into foreign key columns. Moreover, both PostgreSQL and MongoDB support several extensions and plugins like Adminer for database management. MongoDB is wielded by thousands of organizations worldwide for data storage needs or as their applications’ database service. It can be used to manage data for anything from web applications to data warehouses.
