Whether to allow string values to be treated as numbers.

データ型

bool

デフォルト値

true

解説

By default this property is enabled and the connector will treat string values as numeric if they all the values it samples during schema detection are numeric. This can cause type errors later on if the field contains non-numeric values in other documents. If this property is disabled then numeric strings are left as strings although other string-based data types like timestamps will still be detected.

For example, the "code" field in the below bucket would be affected by this setting. By default it would be considered an integer but if this property were enabled it would be treated as a string.

{ "code": "123", "message": "Please restart your computer" }
{ "code": "456", "message": "Urgent update must be applied" }
