Data management system and method of controlling preliminary class

1. A method of data storage in a data storage system, the method comprising:

identifying object headers respectively corresponding to object data;

storing the object data, comprising a first data object and a second data object, at one side of an allocated data chunk, the allocated data chunk comprising a single line of blocks; and

storing the object headers, comprising a first object header for the first data object and a second object header for the second data object, at another side of the allocated data chunk.

2. The method of claim 1 , further comprising:

deleting or aggregating the object data such that invalid data causes the allocated data chunk to be fragmented;

reading one of the object headers to determine a corresponding one of the object data is a valid data object; and

moving the valid data object to a new allocated data chunk.

3. The method of claim 1 , further comprising:

reading one of the object headers to determine a corresponding one of the object data is an invalid data object; and

refraining from reading the invalid data object.

4. The method of claim 1 , further comprising:

reading the object headers to determine that the object data are valid object data;

determining that the valid object data correspond to a single object;

concatenating the valid object data; and

writing the valid object data as the single object to a drive.

5. The method of claim 1 , further comprising:

staging the object data into a contiguous buffer in a persistent memory;

determining the contiguous buffer has reached a threshold; and

sequentially writing data corresponding to the object data to a drive.

6. The method of claim 1 , further comprising:

determining one of the object headers has an attribute set to long; and

staging the one of the object headers in an active block in a persistent memory and writing the active block to a drive; or

directly writing the active block to the drive.

7. The method of claim 1 , further comprising:

determining one of the object headers has an attribute set to short; and

caching the one of the object headers in a persistent memory.

8. A data storage system configured to store data, the data storage system comprising a storage node comprising a key-value store for storing data, and a data management node for sending or retrieving the data from the storage node, wherein the data management node is configured to:

identify object headers respectively corresponding to object data;

store the object data, comprising a first data object and a second data object, at one side of an allocated data chunk, the allocated data chunk comprising a single line of blocks; and

store the object headers, comprising a first object header for the first data object and a second object header for the second data object, at another side of the allocated data chunk.

9. The data storage system of claim 8 , wherein the data management node is further configured to:

delete or aggregate the object data such that invalid data causes the allocated data chunk to be fragmented;

read one of the object headers to determine a corresponding one of the object data is a valid data object; and

move the valid data object to a new allocated data chunk.

10. The data storage system of claim 8 , wherein the data management node is further configured to:

read one of the object headers to determine a corresponding one of the object data is an invalid data object; and

refrain from reading the invalid data object.

11. The data storage system of claim 8 , wherein the data management node is further configured to:

read the object headers to determine that the object data are valid object data;

determine that the valid object data correspond to a single object;

concatenate the valid object data; and

write the valid object data as the single object to a drive.

12. The data storage system of claim 8 , wherein the data management node is further configured to:

stage the object data into a contiguous buffer in a persistent memory;

determine the contiguous buffer has reached a threshold; and

sequentially write data corresponding to the object data to a drive.

13. The data storage system of claim 8 , wherein the data management node is further configured to:

determine one of the object headers has an attribute set to long; and

stage the one of the object headers in an active block in a persistent memory and write the active block to a drive; or

directly write the active block to the drive.

14. The data storage system of claim 8 , wherein the data management node is further configured to:

determine one of the object headers has an attribute set to short; and

cache the one of the object headers in a persistent memory.

15. A non-transitory computer readable medium implemented on a distributed object store system, the non-transitory computer readable medium having computer code that, when executed on a processor, implements a method of data storage by a data management node, the method comprising:

identifying object headers respectively corresponding to object data;

storing the object data, comprising a first data object and a second data object, at one side of an allocated data chunk, the allocated data chunk comprising a single line of blocks; and

storing the object headers, comprising a first object header for the first data object and a second object header for the second data object, at another side of the allocated data chunk.

16. The non-transitory computer readable medium of claim 15 , wherein the computer code, when executed by the processor, further implements the method of data storage by causing the data management node to:

delete or aggregate the object data such that invalid data causes the allocated data chunk to be fragmented;

read one of the object headers to determine a corresponding one of the object data is a valid data object; and

move the valid data object to a new allocated data chunk.

17. The non-transitory computer readable medium of claim 15 , wherein the computer code, when executed by the processor, further implements the method of data storage by causing the data management node to:

read one of the object headers to determine a corresponding one of the object data is an invalid data object; and

refrain from reading the invalid data object.

18. The non-transitory computer readable medium of claim 15 , wherein the computer code, when executed by the processor, further implements the method of data storage by causing the data management node to:

read the object headers to determine that the object data are valid object data;

determine that the valid object data correspond to a single object;

concatenate the valid object data; and

write the valid object data as the single object to a drive.

19. The non-transitory computer readable medium of claim 15 , wherein the computer code, when executed by the processor, further implements the method of data storage by causing the data management node to:

stage the object data into a contiguous buffer in a persistent memory;

determine the contiguous buffer has reached a threshold; and

sequentially write data corresponding to the object data to a drive.

20. The non-transitory computer readable medium of claim 15 , wherein the computer code, when executed by the processor, further implements the method of data storage by causing the data management node to:

determine one of the object headers has an attribute set to short; and

cache the one of the object headers in a persistent memory.
