I need to do some maintenance on my data warehouse. What do I do?

Head to the Settings tab in your Warehouse menu and disable syncing your warehouse. When you re-enable the warehouse, we’ll automatically sync the events we saw while it was disabled.

Can we transform or clean up old data to new formats or specs?

This is a common question if the data you’re collecting has evolved over time. For example, if you used to track the event Signup but now track Signed Up, you’d probably like to merge those two tables to make querying simple and understandable.

We don’t currently have a good way to let you define versions or transformations of the data as your data collection spec changes. Some customers have used Redshift Views to combine different events. In the meantime, we’re looking into ways we can let you do this simply within our interface – open to suggestions as to how you’d prefer we do it!


If you have any questions or see anywhere we can improve our documentation, please let us know or kick off a conversation in the Segment Community!
