## Strategy Details

By default, Mage will attempt to infer your data’s schema from a sample of documents.

* `strategy: infer` — Mage will try to infer a unified schema from the data. If multiple schemas exist, Mage will pick the one covering the most data points.
* `strategy: combine` — Mage will combine the data into a single `_document` column as an object.
