This operation should behave exactly like DescribeTable,
except it does not contain a response body.
REST NAMESPACE ONLY
REST namespace conveys the result through the HTTP status code with no response body.
The REST response maps to the TableExistsResponse model as follows:
a 200 response means the table exists; a 404 response means it does not
response headers map to context via the header. prefix (see the Context schema)
For DirectoryNamespace implementation, a table exists if either:
The table has Lance data versions (regular table created with CreateTable)
A .lance-reserved file exists in the table directory (declared table created with DeclareTable)
string identifier of an object in a namespace, following the Lance Namespace spec.
When the value is equal to the delimiter, it represents the root namespace.
For example, v1/namespace/$/list performs a ListNamespace on the root namespace.
Arbitrary context as key-value pairs.
How to use the context is custom to the specific implementation.
On a request, it carries caller-provided context to the implementation.
On a response, it carries implementation-provided context back to the caller.
REST NAMESPACE ONLY
Context entries are mapped to and from HTTP headers using the header. prefix:
On a request, any entry whose key starts with header. is sent as an HTTP
request header with the prefix stripped. For example, the entry
{"header.Authorization": "Bearer abc"} is sent as the request header
Authorization: Bearer abc.
On a response, every HTTP response header is returned as an entry whose key is the
header name prefixed with header.. For example, the response header
x-request-id: abc123 is returned as the entry {"header.x-request-id": "abc123"}.
