predict, based on an execution plan for the query, a processing complexity of the query, wherein the processing complexity of the query indicates a quantity of computing resources required to execute the query;

determine, based on the processing complexity of the query and for each of a plurality of virtual warehouses, a plurality of predicted processing times, wherein each predicted processing time of the plurality of predicted processing times predicts how long a given virtual warehouse of the plurality of virtual warehouses will take to execute the query;

select, based on the plurality of predicted processing times, a first virtual warehouse, of the plurality of virtual warehouses, to execute the query, wherein each of the plurality of virtual warehouses comprises a respective set of computing resources;

modify, based on the plurality of predicted processing times and based on first computing resources available to the selected first virtual warehouse:

the query, and

a quantity of the first computing resources used to execute one or more other queries executing on the first virtual warehouse; and

cause the first virtual warehouse to execute the modified query.

3. The computing device of claim 1 , wherein the instructions, when executed by the one or more processors, further cause the computing device to modify the query by causing the computing device to remove one or more wildcard characters from the query.

4. The computing device of claim 1 , wherein the instructions, when executed by the one or more processors, cause the computing device to:

cause output of a notification that comprises a cost corresponding to execution of the query, wherein the cost is based on the processing complexity of the query.

5. The computing device of claim 1 , wherein the instructions, when executed by the one or more processors, further cause the computing device to select the first virtual warehouse by causing the computing device to:

identify the plurality of virtual warehouses;

determine processing capabilities of the plurality of virtual warehouses; and

select, based on the operating status, the plurality of predicted processing times, and the processing capabilities, the first virtual warehouse.

6. The computing device of claim 1 , wherein the instructions, when executed by the one or more processors, cause the computing device to:

modify, based on the processing complexity of the query, a quantity of computing resources available to one or more servers that provide the first virtual warehouse.

7. The computing device of claim 1 , wherein the instructions, when executed by the one or more processors, cause the computing device to:

determine a frequency of queries during a time period; and

modify, based on the frequency, a size of the plurality of virtual warehouses.

8. A method comprising:

receiving, from a user device, a request to execute a query on at least one of a plurality of data warehouses;

predicting, based on an execution plan for the query, a processing complexity of the query, wherein the processing complexity of the query indicates a quantity of computing resources required to execute the query;

determining, based on the processing complexity of the query and for each of a plurality of virtual warehouses, a plurality of predicted processing times, wherein each predicted processing time of the plurality of predicted processing times predicts how long a given virtual warehouse of the plurality of virtual warehouses will take to execute the query;

selecting, based on the plurality of predicted processing times, a first virtual warehouse, of the plurality of virtual warehouses, to execute the query, wherein each of the plurality of virtual warehouses comprises a respective set of computing resources;

modifying, based on the plurality of predicted processing times and based on first computing resources available to the selected first virtual warehouse:

the query, and

a quantity of the first computing resources used to execute one or more other queries executing on the first virtual warehouse; and

causing the first virtual warehouse to execute the modified query.

9. The method of claim 8 , further comprising:

identifying the plurality of virtual warehouses;

determining an operating status of the plurality of virtual warehouses; and

determining processing capabilities of the plurality of virtual warehouses, wherein determining the plurality of predicted processing times is further based on the operating status and the processing capabilities.

10. The method of claim 8 , wherein the modifying the query comprises removing one or more wildcard characters from the query.

11. The method of claim 8 , further comprising:

causing output of a notification that comprises a cost corresponding to execution of the query, wherein the cost is based on the processing complexity of the query.
