24 alternatives to Script to compare Postgres data between two points in time
https://github.com/denvaar/pgdiff I cobbled together various programs into a bash script to compare how data changes between two points in time. My idea was basically to have a `git diff` but for data inside postgres. I wanted a util like this to help get to know a new code base: Interact with an app and watch how the data changes. You run the script with a given key (anything) before interacting with an app, then run it again with the same key to see the data diff. I'm not much of a bash scripter, as you can probably see from the script, but it was a fun and useful tool…
A bash script that captures and compares PostgreSQL database changes between two points in time. Users run the script before and after interacting with an application to see what data changed, similar to how git diff… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. Script to compare Postgres data between two points in time launched in 2021; newer entries below may have overtaken it.

We've been hard at work for a few weeks and thought it's time for another update. In case you missed our first post, PostgresML is an end-to-end machine learning solution, running alongside your favorite database. This time we have more of a suite offering: project management, visibility into the datasets and the deployment pipeline decision making. Let us know what you think! Demo link is on the page, and also here: https://demo.postgresml.org

Gleb, Alex, Erez and Simon here – we are building an open-source tool for comparing data within and across databases at any scale. The repo is at https://github.com/datafold/data-diff, and our home page is https://datafold.com/. As a company, Datafold builds tools for data engineers to automate the most tedious and error-prone tasks falling through the cracks of the modern data stack, such as data testing and lineage. We launched two years ago with a tool for regression-testing changes to ETL code…

Hello HN, I am Sai Srirampur, one of the Co-founders of PeerDB. (https://github.com/PeerDB-io/peerdb). We spent the past 7 months building a solid experience to replicate data from Postgres to data warehouses. Now we're expanding to queues. PeerDB Streams provides a simple and native way to replicate changes as they happen in Postgres to Queues (Kafka, Redpanda, Google PubSub, etc). We use Postgres logical decoding to enable Change Data Capture (CDC). Blog post here: https://blog.peerdb.io/peerdb-streams-simple-native-postgres.... 10-min quickstart here:…

Hey HN, I’m an engineer at Supabase [0] and one of the creators of this demo. My team and I have been working hard to bring developers the next version of Supabase Realtime. The current version of Realtime [1] is a Change Data Capture (CDC) server for a PostgreSQL database that broadcasts changes via WebSockets to authorized subscribers. It’s written in Elixir/Phoenix. The server utilizes PostgreSQL’s logical replication functionality, which writes database changes to Write-Ahead Logging (WAL) segment files, and a replication slot, responsible for managing and retaining WAL files.…

I created a web page to compare different analytical databases (both self-managed and services, open-source and proprietary) on a realistic dataset. It contains 20+ databases, each with installation and data loading scripts. And they can be compared to each other on a set of 43 queries, by data load time or by storage size. There are switches to select different types of databases for comparison - for example, only MySQL compatible or PostgreSQL compatible. If you play with the switches, many interesting details will be uncovered. Full description:…

Note: this is an update to [this](https://news.ycombinator.com/item?id=44568529) "Show HN" post. timep is a state-of-the-art [debug-]trap-based bash profiler that is efficient and extremely accurate. Unlike other profilers, timep records: 1. per-command wall-clock time 2. per-command CPU time, and 3. the hierarchy of parent function calls /subshells for each command the wall-clock + CPU time combination allows you to determine if a particular command is CPU-bound or IO-bound, and the hierarchical logging gives you a map of how the code actually executed. The standout…

This is like 4 years old, but I’m braver now and ready to share stuff with this community. I’ve been a lurker for a while. I made this tool - it’s kind of like “explain” but it tells you about what locks would be required by the query. I was making it as part of a larger tool that would try to prevent deadlocks during migrations at my last company, I never finished it.

From the company behind Dolt—the world's first fully versioned database—comes DoltgreSQL, which implements PostgreSQL's variant of SQL. DoltgreSQL is at a very early stage, and we have quite a lot of work left to do, but we'd love to hear all thoughts and opinions!
