matchKey

A key that allows grouping of multiple input attributes into a unified matching group.

For example, consider a scenario where the source table contains various addresses, such as business_address and shipping_address. By assigning a matchKey called address to both attributes, Entity Resolution will match records across these fields to create a consolidated matching group.

If no matchKey is specified for a column, it won't be utilized for matching purposes but will still be included in the output table.
