Abstract

Techniques and structures for providing a multitenant environment having both a relational database and a non-relational database. A database query is received with at least one server computing device providing a multitenant environment having a relational database system and a non-relational database system, the database query in a format corresponding to the relational database system. The query is parsed with the at least one server computing device to find one or more components of the query directed to data stored in the non-relational database system. One or more components of the query directed to data stored in the non-relational database system are converted to one or more scans of the non-relational database system. Results from the query of the relational database system and results from the one or more scans of the non-relational database system are collected. The results from the query and the results of the one or more scans to a combined result are combined. The combined results are provided to a client entity.

Claims

1. A system comprising:

a group of one or more server computing devices configured to provide a multitenant service environment, wherein the multitenant environment stores data for multiple client entities each identified by a tenant identifier (ID) having one of one or more users associated with the tenant ID, wherein users of each of multiple client entities can only access data identified by a tenant ID associated with the respective client entity, and wherein the multitenant environment is provided by an entity separate from the client entities, and provides on-demand service to the client entities;

at least one relational database system coupled with the one or more server computing devices, the at least one relational database system to provide data management services to tenants of the multitenant environment;

at least one non-relational database system coupled with the one or more server computing devices, the at least one non-relational database system to provide data management services to tenants of the multitenant environment;

a database search agent coupled with the at least one relational database system and with the at least one non-relational database system, the database search agent to receive a database query in a format corresponding to the relational database system, to parse the query to find one or more components of the query directed to data stored in the non-relational database system, to convert one or more components of the query directed to data stored in the non-relational database system to one or more scans of the non-relational database system, to collect results from the query of the relational database system and results from the one or more scans of the non-relational database system, to combine the results from the query and the results of the one or more scans to a combined result, and to provide the combined result to a client entity.

2. The system of claim 1 wherein the multitenant environment comprises a multitenant on-demand services environment.

3. The system of claim 2 wherein the multitenant on-demand service environment comprises at least a multitenant database environment.

4. The system of claim 1 wherein data stored in the non-relational database is immutable.

5. The system of claim 1 wherein the at least one non-relational database system to provide the ability to run one or more tenant-specific tables that use a single common physical non-relational database table.

6. A method comprising:

receiving a database query with at least one server computing device providing a multitenant environment having a relational database system and a non-relational database system, the database query in a format corresponding to the relational database system;

parsing the query with the at least one server computing device to find one or more components of the query directed to data stored in the non-relational database system;

converting with the at least one server computing device, one or more components of the query directed to data stored in the non-relational database system to one or more scans of the non-relational database system;

collecting results from the query of the relational database system and results from the one or more scans of the non-relational database system;

combining the results from the query and the results of the one or more scans to a combined result; and

providing the combined result to a client entity.

7. The method of claim 6 wherein the multitenant environment comprises a multitenant on-demand services environment.

8. The method of claim 7 wherein the multitenant on-demand service environment comprises at least a multitenant database environment.

9. The method of claim 6 wherein data stored in the non-relational database is immutable.

10. The method of claim 6 wherein the at least one non-relational database system to provide the ability to run one or more tenant-specific tables that use a single common physical non-relational database table.

11. A non-transitory computer-readable medium having stored thereon instructions that, when executed by one or more processors, cause the one or more processors to:

receive a database query with at least one server computing device providing a multitenant environment having a relational database system and a non-relational database system, the database query in a format corresponding to the relational database system;

parse the query with the at least one server computing device to find one or more components of the query directed to data stored in the non-relational database system;

convert with the at least one server computing device, one or more components of the query directed to data stored in the non-relational database system to one or more scans of the non-relational database system;

collect results from the query of the relational database system and results from the one or more scans of the non-relational database system;

combine the results from the query and the results of the one or more scans to a combined result; and

provide the combined result to a client entity.

12. The non-transitory computer-readable medium of claim 11 wherein the multitenant environment comprises a multitenant on-demand services environment.

13. The non-transitory computer-readable medium of claim 12 wherein the multitenant on-demand service environment comprises at least a multitenant database environment.

14. The non-transitory computer-readable medium of claim 11 wherein data stored in the non-relational database is immutable.

15. The non-transitory computer-readable medium of claim 11 wherein the at least one non-relational database system to provide the ability to run one or more tenant-specific tables that use a single common physical non-relational database table.

16. An apparatus comprising:

means for receiving a database query with at least one server computing device providing a multitenant environment having a relational database system and a non-relational database system, the database query in a format corresponding to the relational database system;

means for parsing the query with the at least one server computing device to find one or more components of the query directed to data stored in the non-relational database system;

means for converting with the at least one server computing device, one or more components of the query directed to data stored in the non-relational database system to one or more scans of the non-relational database system;

means for collecting results from the query of the relational database system and results from the one or more scans of the non-relational database system;

means for combining the results from the query and the results of the one or more scans to a combined result; and

means for providing the combined result to a client entity.

17. The apparatus of claim 16 wherein the multitenant environment comprises a multitenant on-demand services environment.

18. The apparatus of claim 17 wherein the multitenant on-demand service environment comprises at least a multitenant database environment.

19. The apparatus of claim 16 wherein data stored in the non-relational database is immutable.

20. The apparatus of claim 16 wherein the at least one non-relational database system to provide the ability to run one or more tenant-specific tables that use a single common physical non-relational database table.
