+Notes:
+* Not all the OpenSearch SQL Type has correspond OpenSearch Type. e.g. data and time. To use function which required such data type, user should explicitly convert the data type.
+* date*: Maps to `timestamp` by default. Based on the "format" property `date` can map to `date` or `time`. See list of supported named formats `here <https://opensearch.org/docs/latest/field-types/supported-field-types/date/>`_.
+For example, `basic_date` will map to a `date` type, and `basic_time` will map to a `time` type.
