Determines how the provider will scan the data to determine the fields and data types in each document collection.
データ型
string
デフォルト値
"RowScan"
解説
Since Apache CouchDB is schema-less, the columns in a table must be determined by scanning table rows. Set TypeDetectionScheme to toggle the automatic discovery of data types. Set RowScanDepth to configure type detection.
| None | Setting TypeDetectionScheme to None will return all columns as a string type. |
| RowScan | Setting TypeDetectionScheme to RowScan will scan rows to heuristically determine the data type. The RowScanDepth property determines the number of rows to be scanned. |

Type detection is part of 自動スキーマ検出. Set FlattenArrays and FlattenObjects to configure how the connector projects columns over the hierarchical data.
You can fine-tune the discovered columns and data types by calling CreateSchema to generate a schema file. Schema files have a simple format that makes it easy to change column behavior.
