Pointer-based dynamic data structures in key-value stores

1. A computer-implemented method, comprising:

receiving data structures in memory space;

creating micro-heaps on a per-data structure basis, wherein each data structure is associated with a unique micro-heap allocator, wherein each micro-heap includes a micro-heap allocator and the associated data structure; and

storing the data structures in a key-value store, wherein values of the key-value store are associated with the data structures.

2. The computer-implemented method of claim 1 , comprising creating secondary micro-heaps on a per logical group basis, wherein a logical group comprises a plurality of data structures.

3. The computer-implemented method of claim 1 , comprising relocating the data structures, wherein relocating the data structures includes relocating memory managed by the micro-heap allocators associated with the data structures, wherein the relocating does not include serializing.

4. The computer-implemented method of claim 1 , comprising copying the data structures to memory managed by the micro-heap allocator associated with the data structures, wherein the copying does not include serializing.

5. The computer-implemented method of claim 1 , wherein each micro-heap is associated with a micro-heap allocator configured for memory management.

6. The computer-implemented method of claim 1 , comprising maintaining the memory space, wherein the memory space includes metadata memory space and allocated data memory space in a contiguous region of the memory space.

7. The computer-implemented method of claim 6 , comprising expanding the maintained memory space by linking a plurality of micro-heap allocators together.

8. The computer-implemented method of claim 6 , wherein the contiguous region of the memory space uses data transfers selected from the group consisting of: direct memory access (DMA) and remote direct memory access (RDMA).

9. A computer program product, the computer program product comprising:

one or more computer readable storage media, and program instructions collectively stored on the one or more computer readable storage media, the program instructions comprising:

program instructions to receive data structures in memory space;

program instructions to create micro-heaps on a per-data structure basis, wherein each data structure is associated with a unique micro-heap allocator, wherein each micro-heap includes a micro-heap allocator and the associated data structure; and

program instructions to store the data structures in a key-value store, wherein values of the key-value store are associated with the data structures.

10. The computer program product of claim 9 , comprising program instructions to create secondary micro-heaps on a per logical group basis, wherein a logical group comprises a plurality of data structures.

11. The computer program product of claim 9 , comprising program instructions to relocate the data structures, wherein relocating the data structures includes relocating memory managed by the micro-heap allocators associated with the data structures, wherein the relocating does not include serializing.

12. The computer program product of claim 9 , comprising program instructions to copy the data structures to memory managed by the micro-heap allocator associated with the data structures, wherein the copying does not include serializing.

13. The computer program product of claim 9 , wherein each micro-heap is associated with a micro-heap allocator configured for memory management.

14. The computer program product of claim 9 , comprising program instructions to maintain the memory space, wherein the memory space includes metadata memory space and allocated data memory space in a contiguous region of the memory space.

15. The computer program product of claim 14 , comprising program instructions to expand the maintained memory space by linking a plurality of micro-heap allocators together.

16. The computer program product of claim 14 , wherein the contiguous region of the memory space uses data transfers selected from the group consisting of: direct memory access (DMA) and remote direct memory access (RDMA).

17. A system, comprising:

a processor; and

logic integrated with the processor, executable by the processor, or integrated with and executable by the processor, the logic being configured to:

receive data structures in memory space;

create micro-heaps on a per-data structure basis, wherein each data structure is associated with a unique micro-heap allocator, wherein each micro-heap includes a micro-heap allocator and the associated data structure; and

store the data structures in a key-value store, wherein values of the key-value store are associated with the data structures.

18. The system of claim 17 , comprising logic configured to create secondary micro-heaps on a per logical group basis, wherein a logical group comprises a plurality of data structures.

19. The system of claim 17 , comprising logic configured to relocate the data structures, wherein relocating the data structures includes relocating memory managed by the micro-heap allocators associated with the data structures, wherein the relocating does not include serializing.

20. The system of claim 17 , comprising logic configured to copy the data structures to memory managed by the micro-heap allocator associated with the data structures, wherein the copying does not include serializing.
