Sink (data)
The destination where data is written at the end of a workflow or pipeline. Common sinks: HubSpot CRM, Google Sheets, Xero, a database, or a Slack message. Every automation has at least one sink where the processed data ends up.
Expert insight
A data sink (the final destination a pipeline writes to) needs to handle receiving the same data more than once gracefully, a pipeline that retries a failed write will send the same batch to the sink again, and a sink without deduplication or upsert logic ends up with duplicate records from what was meant to be a single logical write.
In a real workflow
A data warehouse is the sink where cleaned events finally land.
Common mistakes
- Multiple sinks with diverging data.
- No checks before writing to the sink.
Complexity level
Anyone can understand this no technical background needed.
