@lancedb/lancedb • Docs @lancedb/lancedb / Connection Class: abstract Connection A LanceDB Connection that allows you to open tables and create new ones. Connection could be local against filesystem or remote against a server. A Connection is intended to be a long lived object and may hold open resources such as HTTP connection pools. This is generally fine and a single connection should be shared if it is going to be used many times. However, if you are finished with a connection, you may call close to eagerly free these resources. Any call to a Connection method after it has been closed will result in an error. Closing a connection is optional. Connections will automatically be closed when they are garbage collected. Any created tables are independent and will continue to work even if the underlying connection has been closed. Methods close() abstract close(): void Close the connection, releasing any underlying resources. It is safe to call this method multiple times. Any attempt to use the connection after it is closed will result in an error.

Parameters options: object & Partial<CreateTableOptions> The options object. Returns Promise<Table> createTable(name, data, options) abstract createTable( name, data, options?): Promise<Table> Creates a new Table and initialize it with new data.
