Do I need to rerun the analysis every time I add a new data source?

Can I add to an existing dataset?

Yes, you can upsert to an existing dataset via the Dataset section on your dashboard or use the dataset upsert function if you prefer coding. Note that you can add new fields, but field types and formats must remain consistent.

Do I need to rerun the analysis every time I add a new data source?

When new entries are added to your dataset or existing data is edited - in fields that have been used for any analysis - you will need to rerun the workflows, so that the new items or the updates are included in the analysis.

Do filters slow down the process?

No, filters are quick to run.
