Snowflake Table Freshness Watchdog to Slack
Checks the last-loaded timestamp of your critical Snowflake tables on a schedule and posts a Slack alert the moment any table goes stale past its freshness SLA.
How it runs
The automated pipeline, trigger to output.
- TriggerEvery 15 minutes (business hours)
- ActionQuery last-load timestamps per tableSnowflake
- LogicCompute staleness vs per-table SLA
- LogicStop if no tables are stale
- OutputPost stale-table alert to SlackSlack
What it does
Runs a scheduled freshness sweep across a curated list of business-critical Snowflake tables. For each table it reads the most recent load timestamp, compares it against that table's allowed staleness window, and flags any table that has not been updated in time. Healthy runs stay quiet; only breaches trigger a Slack message naming the table, its expected cadence, and how many minutes late it is.
When to use it
Use this when downstream dashboards or models silently break because an upstream load failed and nobody noticed for hours. It gives data teams a single, low-noise heartbeat on the tables that actually matter.
How it works
- 1A schedule fires every 15 minutes during business hours.
- 2A Snowflake query pulls MAX load timestamps for each watched table from the metadata view.
- 3A logic step computes staleness per table and keeps only those past their SLA.
- 4A branch checks whether the breach list is empty and exits quietly if so.
- 5A Slack message lists each stale table with minutes-late and last-load time so an on-call analyst can act immediately.
