Denodo can consume a wide range of data sources through JDBC, ODBC, rest API, etc. mechanisms.
At the moment Denodo supports connecting to cloud storage such as [AWS S3](https://community.denodo.com/kb/en/view/document/How%20to%20connect%20to%20the%20Amazon%20S3%20REST%20API%20from%20Denodo), [Google Cloud Storage](https://community.denodo.com/kb/en/view/document/How%20to%20connect%20to%20Google%20Cloud%20Storage%20from%20Denodo) and [Azure Blob Storage](https://community.denodo.com/kb/en/view/document/How%20to%20connect%20to%20Azure%20Blob%20Storage%20from%20Denodo?category=Data%20Sources). As Tencent COS is a similar object storage service, you could access it through API calls.
Tencent COS supports CSV,JSON,and Parquet files. If you are looking to consume any of these files through Denodo, you can create an appropriate datasource in Denodo based on the file type([JSON](https://community.denodo.com/docs/html/browse/latest/en/vdp/administration/creating_data_sources_and_base_views/json_sources/json_sources),[CSV](https://community.denodo.com/docs/html/browse/latest/en/vdp/administration/creating_data_sources_and_base_views/delimited_file_sources/delimited_file_sources),[Denodo Distributed File System Custom Wrapper](https://community.denodo.com/docs/html/document/denodoconnects/8.0/en/Denodo%20Distributed%20File%20System%20Custom%20Wrapper%20-%20User%20Manual)).Ensure to use HTTP as the data route providing the Cloud storage endpoint and appropriate authentication mechanism.
Hope this helps!
