Count rows in a table

Count the number of rows in table id

REST NAMESPACE ONLY REST namespace returns the response as a plain integer instead of the CountTableRowsResponse JSON object. The REST response maps to the CountTableRowsResponse model as follows:

• the integer response body maps to count
• response headers map to context via the header. prefix (see the Context schema)

POST /v1/table/{id}/count_rows

Authorizations

OAuth2BearerAuthApiKeyAuth

Authorization · string · header · required

The access token received from the authorization server in the OAuth 2.0 flow.

Path Parameters

id · string · required

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.

Query Parameters

delimiter · string

An optional delimiter of the string identifier, following the Lance Namespace spec. When not specified, the $ delimiter must be used.

Body

application/json

identity · object

Identity information of a request.

Show child attributes

context · object

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"}.

Show child attributes

id · string[]

version · integer<int64>

Version of the table to describe. If not specified, server should resolve it to the latest version.

Required range: x >= 0

branch · string

Branch to target. When not specified, the main branch is used.

predicate · string

Optional SQL predicate to filter rows for counting. Field references must use Lance field path syntax: nested fields use dot-separated segments, literal dots require backtick-quoted segments, and backticks inside quoted segments are doubled.

Response

application/json

Result of counting rows in a table

Row count serialized transparently as a bare number for the REST namespace. The CountTableRowsResponse object model is used by non-REST interfaces.
