   schema-tools – Build and Edit JSON Schemas▲5

   We built this in a day to help save some time internally and wanted to share as others might find it useful for managing structured output schemas. There’s a few other tools out there - but none had exactly what we needed! Key Features: 1. Two-Way Editing: Paste in an existing JSON schema and edit it within the UI 2. Data-Type Validations: add validations to fields 3. Local Storage & Version History: track your edits, don’t lose changes Link: https://schematools.herondata.io Source Code: https://github.com/heron-data/schema-tools

    Open-source schema based Change-Data-Capture utility for Postgres▲5

    I am currently working on a Node.js utility for a schema-based approach on CDC for Postgres. It is a lightweight utility that you can plug on top of your existing WAL events service (eg. Debezium, WAL-listener...) and allows you to define schemas to listen to. Instead of listening to raw individual table-level events, you can aggregate those events into high-level schema events automatically. Conceptually, it is like having WAL events but on an SQL view, any modification to a table the view is based on would trigger a high-level event on the view itself. This has many real-world applications…
