Every connection fills a set of tables in your warehouse. Remove data… deletes every row the connection has written and lets the connection start from scratch on its next run. The connection itself, its credentials, its schedule, and its Insights stay.
Use it when the synced data is wrong and you want a clean reload, for example after you fixed a setup problem in the source system, or after a sync that was stopped mid-way. It is the connection-level version of what earlier versions of Indicate called truncating a pipeline.
Three actions on a connection sound alike and do very different things.
Fetch again: keeps everything. Only the saved position of one table, or of every table with Fetch everything again, is dropped, so the next run loads that table from the beginning and replaces what is there. Use it first, it is the gentlest option. See Sync and activity.
Remove data…: deletes every row the connection has written, right now. The connection stays and loads everything again on its next run. Every Insight built on the connection shows no data until that run is through.
Delete connection: removes the connection for good, and optionally its Insights and its data. See Delete a Source Connection.
The dialog lists it under Before you continue:
Every row this connection has written is permanently deleted.
The connection starts from scratch on its next run.
Every Insight built on this connection is affected. Widgets show no data until the reload has run.
The credentials, the schedule, the activity history, the Insights, and their shares are not touched.
Before you start
You need the Admin role.
The rows are gone the moment you confirm. They come back only with the next sync, and only as far back as the source still delivers them. Sources with a limited lookback do not deliver old data again.
Click the database icon in the left rail to open Data sources, then click Connections.
Open the connection and click the Settings tab. Scroll to the Danger zone.
Click Remove data….
The dialog Remove all data from this connection opens and lists what happens. Read it.
Next to Connection name, click Copy, then paste the name into Type the connection name to confirm.
Turn on Start fetching again straight away if the reload should begin now. Otherwise the connection waits for its next scheduled run. Starting straight away is part of the Pro plan.
Click Remove data.
A toast confirms Data removed, or Data removed. A fresh sync starts shortly if you turned the switch on. Watch the reload on the Activity tab.
