Protocol spec does not specify the Content-Type of the POST body for reading table data.

The current Delta Sharing protocol document does not specify what the content type should be of the POST body for the

{prefix}/shares/{share}/schemas/{schema}/tables/{table}/query endpoint.

DataBricks currently uses x-www-form-urlencoded when making requests for data, but the data of the body is actually JSON. To be correct it should use application/json as the content type.

Hi @rustyconover , do you mind sharing how you discovered that "DataBricks currently uses x-www-form-urlencoded when making requests for data"?

[rustyconover]

Hi @zhuansunxt I logged the incoming request to the sharing server.

@rustyconover did you start your own sharing server?

[rustyconover]

Yes, I did.
