Abstract

Methods, systems, and apparatuses for generating notifications corresponding to queries submitted for execution by virtual warehouses are described herein. A request to execute a query may be received. An execution plan, for the query, may be identified. A processing complexity for the query may be predicted based on the query and the execution plan. A notification may be generated based on the processing complexity meeting an alert threshold. A user device may display the notification. A response to the notification comprising a selection of a first virtual warehouse, of a plurality of virtual warehouses, to execute the query may be received.

First claim

What is claimed is:

1. A computing device comprising:
one or more processors; and
memory storing instructions that, when executed by the one or more processors, cause the computing device to:
receive, from a user device, a request to execute a query on at least one of a plurality of data warehouses;
identify an execution plan for the query by determining one or more sub-queries to be executed with respect to one or more of the plurality of data warehouses;
predict, based on the 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; and
cause the first virtual warehouse to execute the query.

2. The computing device of claim 1 , wherein the instructions, when executed by the one or more processors, further cause the computing device to:
identify the plurality of virtual warehouses;
determine an operating status of the plurality of virtual warehouses; and
determine processing capabilities of the plurality of virtual warehouses, wherein the instructions, when executed by the one or more processors, cause the computing device to determine the plurality of predicted processing times further based on the operating status and the processing capabilities.

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, based on the plurality of predicted processing times, 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 an operating status of 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;
identifying an execution plan for the query by determining one or more sub-queries to be executed with respect to one or more of the plurality of data warehouses;
predicting, based on the 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; and
causing the first virtual warehouse to execute the 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 , further comprising:
modifying, based on the plurality of predicted processing times, 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.

12. The method of claim 8 , further comprising:
identifying the plurality of virtual warehouses;
determining an operating status of the plurality of virtual warehouses;
determining processing capabilities of the plurality of virtual warehouses; and
selecting, based on the operating status, the plurality of predicted processing times, and the processing capabilities, the first virtual warehouse.

13. The method of claim 8 , further comprising:
modifying, 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.

14. The method of claim 8 , further comprising:
determining a frequency of queries during a time period; and
modifying, based on the frequency, a size of the plurality of virtual warehouses.

15. One or more non-transitory computer-readable media storing instructions that, when executed by one or more processors of a computing device, cause the computing device to:
receive, from a user device, a request to execute a query on at least one of a plurality of data warehouses;
identify an execution plan for the query by determining one or more sub-queries to be executed with respect to one or more of the plurality of data warehouses;
predict, based on the 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; and
cause the first virtual warehouse to
