MaxCompute can access unstructured data and its metadata stored in data warehouses or data lakes. This topic describes the functions that MaxCompute provides for processing unstructured data.
Use Object Tables and OSS object processing functions
MaxCompute provides the Object Table feature. This feature enables the compute engine to access unstructured data and its metadata stored in Object Storage Service (OSS). MaxCompute also provides functions to process data in OSS files. For more information, see OBJECT TABLE definition.
