What this workflow does

This workflow has 19 nodes and runs on a schedule (every hour) (plus 1 other trigger). Along the way it connects Postgres and DebugHelper.

How it runs

Trigger: On a schedule (every hour) (plus 1 other trigger).

1. Interest Checks RSS (RSS Read): reads an RSS feed
2. Group Buys RSS (RSS Read): reads an RSS feed
3. Insert rows in a table (Postgres): uses Postgres
4. Merge: merges the data from its input branches
5. Filter New Threads (Code): runs custom JavaScript code
6. Loop Over Items (Loop Over Items (Split in Batches)): loops over the items in batches
7. If: checks a condition and branches into true / false
8. Check if Processed (Postgres): select
9. Get geekhack page (HTTP Request): calls an HTTP API
10. Extract author message (HTML): parses or builds HTML

…plus 7 more steps. See the full node list below.
