Abstract

Methods (600-900) for optimizing performance of systems (100, 200). The methods involve determining if a device (108, 108₁, 108₂, . . . , 108_N) has been deployed as a standalone device or a cluster device. The determination can be based on a value of a flag stored in the device (e.g., an appliance) or contents of device registration information stored in a master device of a cluster of devices. The methods also involve automatically delegating data management operations to a centralized Memory Management System (MMS) or a distributed MMS (210) based on results of said determination. The centralized MMS (110) performs relational database management operations (e.g., SQL operations) in response to said data management operations being delegated thereto. The distributed MMS performs grid database management operations (e.g., non-SQL based operations or key-value based operations) in response to said data management operations being delegated thereto.

Claims

1. A method for optimizing performance of systems, comprising:

determining, by at least one electronic circuit, if a device has been deployed as a standalone device or a cluster device;

automatically delegating, by said electronic circuit, data management operations to a centralized Memory Management System (MMS) of said device if it is determined that said device has been deployed as a standalone device; and

automatically delegating, by said electronic circuit, said data management operations to a distributed MMS of said device if it is determined that said device has been deployed as a cluster device.

2. The method according to claim 1, further comprising performing relational database management operations by said centralized MMS in response to said data management operations being delegated thereto.

3. The method according to claim 2, wherein the relational database management operations are achieved using a structured query language.

4. The method according to claim 1, further comprising performing grid database management operations by said distributed MMS in response to said data management operations being delegated thereto.

5. The method according to claim 4, wherein said grid database management operations comprise non-structured query language based operations.

6. The method according to claim 1, further comprising:

receiving, by said electronic circuit, a request from a network device, said request being selected from the group consisting of a data read request, a data write or insert request, a data update request and a data delete request; and

in response to receiving said request, determining if said device has been deployed as a standalone device or a cluster device.

7. The method according to claim 1, wherein said determining step further comprising determining if said device has been deployed as a standalone device or a cluster device based on a value of a flag stored in said device or contents of device registration information stored in a master device of a cluster of devices.

8. A system comprising:

at least one electronic circuit comprising a memory having stored thereon instructions, which when executed by said electronic circuit, cause said electronic circuit to perform the following operations comprising;

determining if a device has been deployed as a standalone device or a cluster device;

automatically delegating data management operations to a centralized Memory Management System (MMS) of said device if it is determined that said device has been deployed as a standalone device; and

automatically delegating said data management operations to a distributed MMS of said device if it is determined that said device has been deployed as a cluster device.

9. The system according to claim 8, wherein said centralized MMS performs relational database management operations in response to said data management operations being delegated thereto.

10. The system according to claim 9, wherein the relational database management operations comprise structured query language based operations.

11. The system according to claim 8, wherein said distributed MMS performs grid database management operations in response to said data management operations being delegated thereto.

12. The system according to claim 11, wherein said grid database management operations comprise non-structured query language based operations.

13. The system according to claim 8, wherein said electronic circuit is further caused to:

receive a request from a network device, said request being selected from the group consisting of a data read request, a data write or insert request, a data update request and a data delete request; and

in response to receiving said request, determine if said device has been deployed as a standalone device or a cluster device.

14. The system according to claim 8, wherein said electronic device determines if said device has been deployed as a standalone device or a cluster device based on a value of a flag stored in said device or contents of device registration information stored in a master device of a cluster of devices.

15. A machine-readable storage medium having instructions stored thereon, which when executed by a machine, cause the machine to perform the following operations comprising:

determining if said machine has been deployed as a standalone machine or a cluster machine;

automatically delegating data management operations to a centralized Memory Management System (MMS) of said machine if it is determined that said machine has been deployed as a standalone machine; and

automatically delegating said data management operations to a distributed MMS of said machine if it is determined that said machine has been deployed as a cluster machine.

16. The machine-readable storage medium according to claim 15, wherein said machine is further caused to perform relational database management operations in response to said data management operations being delegated to said centralized MMS.

17. The machine-readable storage medium according to claim 15, wherein said machine is further caused to perform grid database management operations in response to said data management operations being delegated to said distributed MMS.

18. The machine-readable storage medium according to claim 15, wherein said machine is further caused to:

receive a request from a network device, said request being selected from the group consisting of a data read request, a data write or insert request, a data update request and a data delete request; and

in response to receiving said request, determine if said machine has been deployed as a standalone machine or a cluster machine.

19. The machine-readable storage medium according to claim 15, wherein said machine determines if said machine has been deployed as a standalone machine or a cluster machine based on a value of a flag stored in said machine or contents of machine registration information stored in a master machine of a cluster of machines.
