ingesting a copy of the high-value data from the first cloud storage location into the second cloud storage location in the second format, wherein the first subset of the first set of data in the first format is maintained and not deleted in the first cloud storage location in response to ingesting the copy of the high-value data;

providing an interface for accessing the first and second sets of data;

receiving, via the interface, a first query referencing the first and second sets of data;

determining that the first query references the first subset of the first data;

executing the first query using the first subset of data in the second cloud storage location in the second format and the second set of data;

receiving, via the interface, a second query referencing the first and second sets of data, determining that the second query references a second subset of the first set of data not ingested into the second cloud storage location;

converting the second subset of the first set of data from the first format into a common format;

converting the second set of data from the second format into the common format;

joining the second subset of the first set of data in the common format and the second set of data in the common format to generate joined data; and

executing the second query based on the joined data.

2. The method of claim 1 , wherein the first cloud storage location is in an external cloud storage location and wherein the second cloud storage location is a network-based data warehouse system, wherein the first format is a raw format and the second format is a formatted format used by the network-based data warehouse system.

3. The method of claim 1 , wherein the classifying is performed based on query patterns.

4. The method of claim 1 , wherein the classifying is performed based on scan statistics.

5. The method of claim 1 , wherein the classifying is performed based on metadata received from a client.

6. The method of claim 1 , further comprising:

re-classifying the first subset from high-value data to low-value data; and

in response to re-classifying, deleting the ingested copy of the first subset in the second format.

7. A machine-storage medium embodying instructions that, when executed by a machine, cause the machine to perform operations comprising:

storing a first set of data in a first format in a first cloud storage location;

storing a second set of data in a second format in a second cloud storage location;

classifying a first subset of the first set of data in the first format as high-value data and classifying a second subset of the first set of data as low-value data; and

ingesting a copy of the high-value data from the first cloud storage location into the second cloud storage location in the second format, wherein the first subset of the first set of data in the first format is maintained and not deleted in the first cloud storage location in response to ingesting the copy of the high-value data;

providing an interface for accessing the first and second sets of data;

receiving, via the interface, a first query referencing the first and second sets of data;

determining that the first query references the first subset of the first data;

executing the first query using the first subset of data in the second cloud storage location in the second format and the second set of data;

receiving, via the interface, a second query referencing the first and second sets of data;

determining that the second query references a second subset of the first set of data not ingested into the second cloud storage location;

converting the second subset of the first set of data from the first format into a common format;

converting the second set of data from the second format into the common format;

joining the second subset of the first set of data in the common format and the second set of data in the common format to generate joined data; and

executing the second query based on the joined data.

8. The machine-storage medium of claim 7 , wherein the first cloud storage location is in an external cloud storage location and wherein the second cloud storage location is a network-based data warehouse system, wherein the first format is a raw format and the second format is a formatted format used by the network-based data warehouse system.

9. The machine-storage medium of claim 7 , wherein the classifying is performed based on query patterns.

10. The machine-storage medium of claim 7 , wherein the classifying is performed based on scan statistics.

11. The machine-storage medium of claim 7 , wherein the classifying is performed based on metadata received from a client.

12. The machine-storage medium of claim 7 , further comprising:

re-classifying the first subset from high-value data to low-value data; and

in response to re-classifying, deleting the ingested copy of the first subset in the second format.

13. A system comprising:

at least one hardware processor; and

at least one memory storing instructions that, when executed by the at least one hardware processor, cause the at least one hardware processor to perform operations comprising:

storing a first set of data in a first format in a first cloud storage location;

storing a second set of data in a second format in a second cloud storage location;

classifying a first subset of the first set of data in the first format as high-value data and classifying a second subset of the first set of data as low-value data; and

ingesting a copy of the high-value data from the first cloud storage location into the second cloud storage location in the second format, wherein the first subset of the first set of data in the first format is maintained and not deleted in the first cloud storage location in response to ingesting the copy of the high-value data;

providing an interface for accessing the first and second sets of data;

receiving, via the interface, a first query referencing the first and second sets of data;

determining that the first query references the first subset of the first data;

executing the first query using the first subset of data in the second cloud storage location in the second format and the second set of data;
