| 摘要 | A map corresponding to data blocks with overwritten compressed journal entries is configured. Weighted conditions for each of the overwritten compressed journal entries are calculated. The weighted conditions are arranged in the map from lowest to highest. One of the weighted conditions includes a biasing variable towards selecting data blocks having free space at an end of at least one associated record. | ||

| 主权项 | 1. A method for efficient garbage collection in a compressed journal file system by a processor device in a computing environment, the method comprising: configuring a map corresponding to data blocks with overwritten compressed journal entries; and calculating weighted conditions for each of the overwritten compressed journal entries, wherein the weighted conditions are arranged in the map from lowest to highest; wherein one of the weighted conditions includes a biasing variable towards selecting data blocks having free space at an end of at least one associated record. | ||
