Mastering Data Sync in Postgres: Automating Resource Counts with Triggers

Imagine a bustling library, where every new book or magazine needs to be meticulously logged in the main catalog to keep counts accurate. In the world of databases, we face a similar challenge: how do we keep track of thousands of entries across multiple categories without constant manual updates? Enter Postgres triggers, our silent but tireless librarians, ensuring data stays perfectly synced.

The Core Structure: The "Resources" Table

At the heart of our setup is the resources table, the master catalog that tracks every resource type: articles, boilerplates, templates, and more. The crucial column, total_num, holds the count of each resource category. But here’s the beauty: we don’t manually update this count. Postgres triggers handle it for us, automating updates and maintaining perfect accuracy.

How It Works: Triggers in Action

For every resource—like articles or templates—there’s a corresponding table. When a new item is added to one of these tables, a Postgres trigger fires off, automatically updating the total_num in the resources table.

Here's a quick look at a trigger setup for the articles table:

CREATE TRIGGER update_total_num
AFTER INSERT ON articles
FOR EACH ROW
EXECUTE FUNCTION update_resource_count();

Whenever a new article is added, this trigger calls update_resource_count(), a function that recalculates the total and updates the master table.

The Function Behind the Scenes

Our update_resource_count() function is the brains of the operation:

CREATE OR REPLACE FUNCTION update_resource_count()
RETURNS TRIGGER AS $$
BEGIN
  UPDATE resources
  SET total_num = (SELECT COUNT(*) FROM articles)
  WHERE resource_name = 'articles';
  RETURN NEW;
END;
$$ LANGUAGE plpgsql;

It counts the entries in the articles table and updates the master count, ensuring data integrity. Similar functions and triggers are set up for other resource types, so everything remains in sync.
