Enabling editable tables on a cloud-based data warehouse

1. A method of enabling editable tables on a cloud-based data warehouse, the method comprising:

receiving, by a query manager, a client-provided table;

receiving, by the query manager from a query manager client, a request to create a referencing worksheet using, as data sources, the client-provided table and a database table on the cloud-based data warehouse;

storing, by the query manager, the client-provided table in the schema storage location on the cloud-based data warehouse, wherein the schema storage location is a storage location on the cloud-based data warehouse to which the query manager has read and write access, and wherein the database table is external to the schema storage location;

generating, by the query manager, a database query to create the referencing worksheet, wherein the database query targets the client-provided table in the schema storage location and the database table on the cloud-based data warehouse; and

issuing, by the query manager, the database query to the cloud-based data warehouse.

2. The method of claim 1 , further comprising:

receiving, by the query manager from the query manager client, an update for the client-provided table; and

applying, by the query manager in response to receiving a subsequent request to create the referencing worksheet, the update to the client-provided table stored in the schema storage location on the cloud-based data warehouse.

3. The method of claim 1 , wherein receiving, by the query manager from a query manager client, a request to create a referencing worksheet using, as data sources, the client-provided table and a database table comprises receiving a request to create the referencing worksheet by joining the client-provided table and the database table.

4. The method of claim 1 , wherein the database query comprises an instruction, to the cloud-based data warehouse, to perform a computation using the client-provided table in the schema storage location and the database table on the cloud-based data warehouse.

5. The method of claim 1 ,

wherein receiving, by the query manager, the client-provided table comprises maintaining an updated copy of the client-provided table until the request to create the referencing worksheet is received, and

wherein storing, by the query manager, the client-provided table in the schema storage location on the cloud-based data warehouse comprises sending, by the query manager, the updated copy of the client provided table to the schema storage location on the cloud-based storage warehouse.

6. The method of claim 1 , wherein the client-provided table comprises a join key to the database table.

7. The method of claim 1 , wherein the query manager has read-only access to the database table on the cloud-based data warehouse.

8. An apparatus for enabling editable tables on a cloud-based data warehouse, the apparatus comprising a computer processor, a computer memory operatively coupled to the computer processor, the computer memory having disposed within it computer program instructions that, when executed by the computer processor, cause the apparatus to carry out the steps of:

receiving, by a query manager, a client-provided table;

receiving, by the query manager from a query manager client, a request to create a referencing worksheet using, as data sources, the client-provided table and a database table on the cloud-based data warehouse;

storing, by the query manager, the client-provided table in the schema storage location on the cloud-based data warehouse, wherein the schema storage location is a storage location on the cloud-based data warehouse to which the query manager has read and write access, and wherein the database table is external to the schema storage location;

generating, by the query manager, a database query to create the referencing worksheet, wherein the database query targets the client-provided table in the schema storage location and the database table on the cloud-based data warehouse; and

issuing, by the query manager, the database query to the cloud-based data warehouse.

9. The apparatus of claim 8 , wherein the computer program instructions further cause the apparatus to carry out the steps of:

receiving, by the query manager from the query manager client, an update for the client-provided table; and

applying, by the query manager in response to receiving a subsequent request to create the referencing worksheet, the update to the client-provided table stored in the schema storage location on the cloud-based data warehouse.

10. The apparatus of claim 8 , wherein receiving, by the query manager from a query manager client, a request to create a referencing worksheet using, as data sources, the client-provided table and a database table comprises receiving a request to create the referencing worksheet by joining the client-provided table and the database table.

11. The apparatus of claim 8 , wherein the database query comprises an instruction, to the cloud-based data warehouse, to perform a computation using the client-provided table in the schema storage location and the database table on the cloud-based data warehouse.

12. The method of claim 8 ,

wherein receiving, by the query manager, the client-provided table comprises maintaining an updated copy of the client-provided table until the request to create the referencing worksheet is received, and

wherein storing, by the query manager, the client-provided table in the schema storage location on the cloud-based data warehouse comprises sending, by the query manager, the updated copy of the client provided table to the schema storage location on the cloud-based storage warehouse.

13. The apparatus of claim 8 , wherein the client-provided table comprises a join key to the database table.

14. The apparatus of claim 8 , wherein the query manager has read-only access to the database table on the cloud-based data warehouse.

15. A computer program product for enabling editable tables on a cloud-based data warehouse, the computer program product disposed upon a computer readable medium, the computer program product comprising computer program instructions that, when executed, cause a computer to carry out the steps of:

receiving, by a query manager, a client-provided table;

receiving, by the query manager from a query manager client, a request to create a referencing worksheet using, as data sources, the client-provided table and a database table on the cloud-based data warehouse;

storing, by the query manager, the client-provided table in the schema storage location on the cloud-based data warehouse, wherein the schema storage location is a storage location on the cloud-based data warehouse to which the query manager has read and write access, and wherein the database table is external to the schema storage location;

generating, by the query manager, a database query to create the referencing worksheet, wherein the database query targets the client-provided table in the schema storage location and the database table on the cloud-based data warehouse; and

issuing, by the query manager, the database query to the cloud-based data warehouse.

16. The computer program product of claim 15 , wherein the computer program instructions further cause the computer to carry out the steps of:

receiving, by the query manager from the query manager client, an update for the client-provided table; and

applying, by the query manager in response to receiving a subsequent request to create the referencing worksheet, the update to the client-provided table stored in the schema storage location on the cloud-based data warehouse.

17. The computer program product of claim 15 , wherein receiving, by the query manager from a query manager client, a request to create a referencing worksheet using, as data sources, the client-provided table and a database table comprises receiving a request to create the referencing worksheet by joining the client-provided table and the database table.

18. The computer program product of claim 15 , wherein the database query comprises an instruction, to the cloud-based data warehouse, to perform a computation using the client-provided table in the schema storage location and the database table on the cloud-based data warehouse.

19. The computer program product of claim 15 ,

wherein receiving, by the query manager, the client-provided table comprises maintaining an updated copy of the client-provided table until the request to create the referencing worksheet is received, and

wherein storing, by the query manager, the client-provided table in the schema storage location on the cloud-based data warehouse comprises sending, by the query manager, the updated copy of the client provided table to the schema storage location on the cloud-based storage warehouse.
