   Peerdb Streams – Simple, native Postgres change data capture▲177

   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:…

   Multiplayer Demo Built with Elixir▲221

   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.…

   Pgstream – CDC tool for PostgreSQL with DDL support▲8

   Hi HN, pgstream is an open source CLI tool and Go library for Postgres logical replication events. We have some bigger plans with it, but as of now its main "differentiator" is that it includes not only data changes but also DDL changes in the same ordered and consistent stream. We have developed this because in the Xata platform we handle automatic replication from Postgres to Elasticsearch/OpenSearch. Initially schema changes were problematic because they required us intercepting them at the API layer and then apply them to the search engine. But if the replication is slightly delayed…

    Hey HN, we're Evis and Nick and we're excited to be launching Neosync (https://www.github.com/nucleuscloud/neosync). Neosync is an open source platform that helps developers anonymize production data, generate synthetic data and sync it across their environments for better testing, debugging and developer experience. Most developers and teams have some version of a database seed script that creates some mock data for their local and stage databases. The problem is that production data is messy and it’s very difficult to replicate that with mock data. This causes two big…

    Hi HN, Today we’re launching PowerSync, a Postgres<>SQLite bi-directional sync engine that enables an offline-first app architecture. It currently supports Flutter, React Native and web (JavaScript) using Wasm SQLite in the browser, with more client SDKs on the way. Conrad and I (Ralf) have been working on our sync engine since 2009, originally as part of a full-stack app platform. That version of the system is still used in production worldwide and we’ve learnt a lot from its use cases and scaling. About a year ago we started on spinning off PowerSync as a standalone product that is…

The linked blog post [1] describes how we're thinking about this extension in a Supabase context. I want to emphasise this part: "pg_crdt has not been released onto the Supabase platform (and it may never be). We’re considering many options for offline-sync&#x2F;support and, while CRDTs will undoubtedly factor in, we’re not sure if this is the right approach."

That let us lean on existing rust libs for validation (jsonschema), so the extension's implementation is only 10 lines of code :) https:&#x2F;&#x2F;github.com&#x2F;supabase&#x2F;pg_jsonschema&#x2F;blob&#x2F;fb7ab09bf6050... happy to answer any questions!

    Hi HN! We're Evgeny and Arjun, and we’re building a better way to do analytics with Postgres. We love Postgres for its simplicity, power, and rich ecosystem. But engineers have to still get bogged down with heavyweight and expensive OLAP systems when connecting an analytics data stack. Postgres is amazing at OLTP queries, but not for OLAP queries (large data scans and aggregations). Even in this case, we’ve still heard from countless scaling startups that they still try to use only a read replica to run analytics workloads since they don’t want to deal with the data engineering complexity of…
