REDUCING FRAGMENTATION IN COMPRESSED JOURNAL STORAGE |
| 摘要 |
A data chunk is compressed into a storage block when emitting the data chunk. If the data chunk is unable to be completely compressed into the storage block, attributes of the data chunk are analyzed for determining whether the data chunk should be split. If the data chunk should be split, a remaining portion of the data chunk is compressed to a next chronological storage block. If the data chunk should not be split, all of the data chunk is moved to the next chronological storage block while leaving any remaining space in the storage block as unused. |

1. A method for reducing fragmentation in compressed journal storage by a processor device in a computing environment, the method comprising:
during a compression of a data chunk into a storage block when emitting the data chunk, if the data chunk is unable to be completely compressed into the storage block:
analyzing a plurality of attributes of the data chunk for determining whether the data chunk should be split, wherein:
if the data chunk should be split, a remaining portion of the data chunk is compressed to a next chronological storage block, andif the data chunk should not be split, all of the data chunk is moved to the next chronological storage block while any remaining space in the storage block is left as unused. |
