We expect at least one unique (and usually autoincrement) primary key column so we can deduplicate records properly! Otherwise we will make a best guess on a random column to use to deduplicate.

**Highly recommended!** Usually you want the results to be most recent first so we can skim off only new results, so choose something like `date_created` or your autoincrement `id`. Column names that contain a space must be enclosed within brackets `[ ]`.

We default to what the primary key is on the table as the unique key to deduplicate on. If you prefer another field, select it here.

Query results must have a unique `id` field so we can deduplicate records properly! Otherwise we will make a best guess. You must also include desired ordering and limiting in the query.

**Note: This query must run in less than 30 seconds and it is recommended that you return no more than 5,000 rows**

Usually something auto-incremented like `id`. Must be unique. Column names that contain a space must be enclosed within brackets `[ ]`.

Usually something like `date_updated` or `last_modified`. This should ideally be a datetime column that is set to the current datetime whenever a row is updated.

Trigger on changes to cells in this column only. Leave blank if you want to trigger on changes to cells in all columns.

You should include desired ordering and limiting (usually to 1 record) in the query.

**This query must run in less than ~30 seconds.**
