We’ll see what they are, how they are constructed under the hood, In this post, we will explore various PostgreSQL scripts designed to help monitor database performance, identify issues, and optimize While JSONB can be handy for flexible or semi-structured data, for structured use cases like transaction tags, a fully normalized model with proper indexing offers better query Your query is hard to follow for a few reasons: Your tables are named tab, table2, table3, `table4. When we analyzed JSON has become an essential format for storing and exchanging semi-structured data. g. In my internal research project aimed at understanding the performance of JSONB data under different use cases, I ran multiple How to improve json_agg and json_build_object performance? Asked 4 years, 10 months ago Modified 4 years, 10 months ago Viewed 3k times json_build_object is used to construct a JSON object from a set of key-value pairs, creating a JSON representation of a row or set of PostgreSQL, a robust database management system, offers support for both JSON and JSONB data types. When working with large tables and complex JSON structures in PostgreSQL, read performance for views can often degrade, especially Getting back to your question: Cluttered and oversized inverted tree indexes will indeed improve the performance of your app if you use Postgres tables as giant JSON stores. Postgres JSONB Usage and performance analysis This story focuses on various features that JSONB provides and formulated with a When working with PostgreSQL, it’s common to encounter scenarios where you need to decide between different query patterns to PostgreSQL JSON vs JSONB Performance Benchmark Comprehensive performance comparison between JSON and JSONB data types in PostgreSQL, tested on 1 million records. Both PostgreSQL and MySQL have How well is the Postgre JSON type optimized for large JSON documents? I am especially concerned about partial retrieval (e. JSON is one of the most popular human-readable data formats. In MySQL 8. 2), JSONB (added in 9. A recent webinar shed light on this topic, offering valuable insights into how these popular databases manage JSON data. 4), and HSTORE (added in 8. PostgreSQL’s JSON capabilities have transformed how developers store and query semi-structured data. 0 they specifically state that now the optimizer is smart and can Currently, in our application, we are storing the JSON data as Text type in PostgreSQL. This article contains some quick-and-dirty benchmark results to explore how Postgres's performance changes for the "schemaless" data types when they become large. 3 json column and created a Extracting performance metrics from nested JSON data within PostgreSQL can be tricky, but mastering efficient techniques is crucial. 2 as an extension). It's Summary - PostgreSQL PostgreSQL has poor performance out of the box Requires a decent amount of tuning to get good performance out of it Does not scale well with large number of How to select filtered postgresql jsonb field with performance prioritization? Asked 2 years, 9 months ago Modified 2 years, 9 months ago Viewed 383 times Explore the nuances of PostgreSQL’s text vs JSONB data storage and optimize your database using OpenTelemetry for metrics and . PostgreSQL allows you to store JSON data and perform queries Conclusion PostgreSQL's JSON capabilities provide a powerful and flexible way to work with semi-structured data within a How do JSON and JSONB affect PostgreSQL's performance? JSONB, with its indexing capabilities, enhances performance significantly, I searched the internet and PG documentation for hours and couldn't find any benchmark for it. 3 which introduced json aggregations, however not a lot of people are aware of this functionality. Generating JSON objects and arrays from relational data. This post guides you through the process, focusing on Option 3: Use the JSON_AGG function The JSON_AGG function is an aggregation function from PostgreSQL: Collects all the input values, including nulls, into a JSON array. Boost performance by 40-60% with improved indexing, function caching, and query restructuring. Learn practical PostgreSQL JSON query optimization techniques for 2025. In this post, you will see how this I have a single SELECT that queries both regular postgres tables and a jsonb column. JSONB vs JSON: the Postgres/MySQL showdown that actually matters Schema design, indexing tricks, and performance wars what devs actually care about when picking The Postgres json_agg() function is an aggregate function that collects values from multiple rows and returns them as a single JSON array. Yet many PostgreSQL databases Learn practical PostgreSQL JSON query optimization techniques for 2025. In the age of flexible data models and evolving application needs, developers often debate: "Should I use MongoDB or PostgreSQL In this article, we will explain how to effectively use the JSON data type in PostgreSQL, covering its syntax, functions, and performance Performance: In general, Postgres implementation of window functions is considered more efficient and What considerations are involved in choosing between a jsonb column and a composite type column of the same structure? For example, consider a column like that used Investigating the differences between Postgres JSON and JSONB and their impact on database performance. This In this post we’re going to examine indexes on a JSONB data type. Unfortunately, the I have a table in a PostgreSQL database that includes a JSON column. However when I PostgreSQL JSON Index Summary: in this tutorial, you will learn how to create a PostgreSQL JSON index for a JSONB column to JSON performance test on PostgreSQL vs mySQL using PyMYSQL and Psycopg2 Libraries and FastAPI web application. We are facing few performance impact because of this table.
