Optimizing the Performance

OBS manages partitions based on the UTF-8 encoding range of object names and implements horizontal expansion and dynamic load balancing accordingly. If you use sequential prefixes (sorted by timestamp or in alphabetical order) for object naming, object access requests may be concentrated in a specific partition, resulting in access hotspots. This limits the request rate in the hotspot partition and increases access delay.

Random prefixes are recommended for naming objects, so requests can be evenly distributed across partitions, achieving horizontal expansion.

Example:

In a typical scenario of log archiving, the names of objects to be uploaded are as follows:

yourbucket/obslog/20190610-01.log.tar.gz
yourbucket/obslog/20190610-02.log.tar.gz
yourbucket/obslog/20190610-03.log.tar.gz
yourbucket/obslog/20190610-04.log.tar.gz
...
yourbucket/obslog/20190611-01.log.tar.gz
yourbucket/obslog/20190611-02.log.tar.gz
yourbucket/obslog/20190611-03.log.tar.gz
yourbucket/obslog/20190611-04.log.tar.gz

You are advised to add a hexadecimal hash prefix with three or more digits to each object name.

yourbucket/6ac-obslog/20140610-01.log.tar.gz
yourbucket/b42-obslog/20140610-02.log.tar.gz
yourbucket/17f-obslog/20140610-03.log.tar.gz
yourbucket/ac9-obslog/20140610-04.log.tar.gz
...
yourbucket/95d-obslog/20140611-01.log.tar.gz
yourbucket/4a5-obslog/20140611-02.log.tar.gz
