Specifies the number of rows (objects) to scan when dynamically determining columns for the table.

データ型

string

デフォルト値

"100"

解説

The row scan follows nested objects, counting 1 object array as 1 row. If a schema (RSD) file is not available for the table, such as when using GenerateSchemaFiles the CData Python Connector for REST determines columns dynamically.

Higher values result in a longer request, but will be more accurate.

Setting this value to 0 (zero) parses the entire document.
