MongoDB vs PostgreSQL: What to consider when choosing a database

In specific, GeoSpark seems to be the most complete spatial analytic system because of data types and queries supported. One of the most pivotal features of relational databases that make writing applications simpler is ACID transactions. As far as the isolation levels within database transactions are concerned, PostgreSQL uses the read committed isolation level, by default. It also allows users to tune the read committed isolation level up to the serializable isolation level. I suggest you to go with MongoDB, because it is schema-less, i.e., it permits you to easily manipulate the schema of a table. If you want to add a column, it can be done without much effort.

MongoDB vs PostgreSQL

Partitioning and sharding are essentially about breaking up large datasets into smaller subsets. Sharding implies that the data is stored across multiple computers while partitioning groups this data within a single database instance. BSON skips the keys that aren’t useful for the query, thus making it faster to retrieve data. A user could further define the document’s structure and undertake some development by introducing new fields, reworking data, or developing it whenever they see fit. With MongoDB, you can store data as documents in a binary representation known as binary JSON (BSON). Fields can differ based on the document it is catering to, therefore, there’s no need to declare the structure of documents to the system — documents are self-describing.

Database Scalability:

It stores data in dynamic JSON-like documents and supports easy query, manipulation, and storage of data. PostgreSQL can handle complex joins, outline relationships, and rapidly query data. As it’s structured, it can process large volumes of data and rapidly provide insight and advanced analytics. These features also allow it to integrate well into business intelligence tools and work effectively as a data warehouse. It makes queries execute faster as it’s in a serialization format that effectively archives JSON-like documents.

This parameter controls the number of parallel workers that a single query execution node can use. The default value is two, but somewhere around a quarter to a half of your CPU count is a good option. In Timescale, we start at two and progressively increase it as your CPU increases to match half your CPU. When reviewing a product, users are asked to assess the product’s overall quality, which includes assigning specific ratings for ease of use, value for money, customer support, and functionality.

Enhancements to the document model

MySQL could be next, sonce it’s easier to learn at first and has more resources available. PostgreSQL is less widespread, more challenging and has the fewer resorces, but once you have some experience with MySQL is really easy to learn as well. All these technologies are really widespread and used accross the industry so you won’t make a wrong decision with any of these.

But advanced techniques are available too, such as SP-Gist, GiST, GIN, KNN Gist, and BRIN, spanning indexes and bloom filters. While document databases are able to do JOINs, they’re performed in a different way from multi-page SQL statements that are often needed and generated automatically by BI tools. Still, MongoDB has an ODBC connector enabling SQL access primarily from BI tools. MongoDB relies on a distributed architecture allowing users to scale out across numerous instances. It’s capable of powering massive applications regardless of it being measured by data sizes or users.

This would be beneficial to use when embedding may result in data duplication but insufficient read performance advantages outweigh the implications of the duplications. On the other hand, MongoDB allows you to store data in any structure that can be quickly accessed by indexing, no matter how deeply nested in arrays or subdocuments. Since it’s non-relational, MongoDB uses collections instead of tables. A foreign key is simply a set of attributes in a table that refers to the primary key of another table.

MongoDB vs PostgreSQL

It all comes down to the type of database you’re looking for based on your unique requirements — a document database or a relational database. This is a reliable, enterprise-grade, open-source SQL database with more than three decades of history behind it. All you could ever look for in a relational database is here for you.

Unlike MongoDB, PostgreSQL depends on a scale-up strategy (vertical scaling) for data volumes and scaling writes. It’s performed by adding more hardware resources like disks, CPUs, and memory to an existing database node. On the other hand, PostgreSQL supports foreign keys as it’s SQL-compliant.

MongoDB vs PostgreSQL

We call it “relational” because the values in a table and tables themselves are related, making it possible to run queries across many tables at the same time. The upsides of SQL include the vast ecosystem of tools, integrations, and programming languages built to use SQL databases. It is likely that you can easily find help to make your SQL database project in general and PostgreSQL project in particular work.

Since these are two of the most important and common database solutions on the market today, it is essential that you know exactly what you need for your company and how to use your database to its full potential. By proceeding below, I hereby agree to use LiveChat as an external third party technology. This may involve a transfer of my personal data (e.g. IP Address) to third parties in- or outside mongodb vs postgresql of Europe. You might be required to divert resources to find new solutions for scaling through caching or denormalizing data, or by employing alternative strategies. If you choose to give up on SQL, that means leaving behind that expansive tech ecosystem that utilizes SQL already. That’s a simpler step to take if you’re working on a new application or intend to modernize one that already exists.

  • As an astute reader should already be able to tell, the real question is not MongoDB vs. Postgres, but the best document database versus the best relational database.
  • It will help simplify the ETL and management process of both the data sources and destinations.
  • A schema allows for strong data consistency and integrity, as each column holds a specific data type.
  • Certain other databases have emulated PostgreSQL’s approach to linking APIs from languages to its databases.
  • Postgres does use its own flavor of SQL called PL/pgSQL (procedural language/postgreSQL).
  • Databases in particular can be challenging to settle on, especially if you’re unclear about how your data will be used.

Other data integration methods like ELT and ReverseETL can be just as challenging if you lack a large data engineering team. When comparing MongoDB and MySQL in terms of user-friendliness, different aspects come into play. Common use cases for MongoDB include customer analytics, content management, business transactions, and product data. Thanks to its ability to scale, the database is also ideal for mobile solutions that need to be scaled to millions of users. While PostgreSQL supports replication, features that are more advanced (e.g. automatic failover) require support by third-party products that have been developed independent of PostgreSQL. This approach tends to be more complex and works more slowly than MangoDB’s in-built ability to heal itself.

Rethink the way you share the data between micro-services with Change-Data-Capture

The defining and implementation of ACID transactions is highly complex, and we simply don’t have the space to detail it all here. Also, MongoDB introduces elements to the document model and query engine, allowing them to handle time and geospatial data tagging. This increases the query types and analytics you can undertake on a database. As PostgreSQL is similar to SQL databases, it offers ACID compliance. It’s reliable for processing transactions and ensuring data consistency.
