F64116045 opened a new pull request, #11091: URL: https://github.com/apache/ozone/pull/11091
## What changes were proposed in this pull request? `OmKeyInfo.verifyAndGetKeyLocations()` calls `createLocationList()` only to iterate over the existing block locations and populate `allocatedBlockLocations`. This change iterates over `getLocationLists()` directly, avoiding the intermediate flattened list without changing the resulting block map. ## What is the link to the Apache JIRA https://issues.apache.org/jira/browse/HDDS-16252 ## How was this patch tested? A local JMH benchmark compared the affected loop with 1, 16, and 128 locations split across 1 or 4 internal lists. | Locations / lists | `createLocationList()` | `getLocationLists()` | |---:|---:|---:| | 1 / 1 | 544 B/op | 160 B/op | | 1 / 4 | 808 B/op | 160 B/op | | 16 / 1 | 1,624 B/op | 1,056 B/op | | 16 / 4 | 1,888 B/op | 1,056 B/op | | 128 / 1 | 12,280 B/op | 9,904 B/op | | 128 / 4 | 12,544 B/op | 9,904 B/op | JMH 1.37, OpenJDK 17.0.17, 1 thread, 2 forks, `-prof gc`. -- This is an automated message from the Apache Git Service.
