* #7641 - Changing segment distribution algorithm to distribute segments to multiple segment cache locations * Fixing indentation * WIP * Adding interface for location strategy selection, least bytes used strategy impl, round-robin strategy impl, locationSelectorStrategy config with least bytes used strategy as the default strategy * fixing code style * Fixing test * Adding a method visible only for testing, fixing tests * 1. Changing the method contract to return an iterator of locations instead of a single best location. 2. Check style fixes * fixing the conditional statement * Added testSegmentDistributionUsingLeastBytesUsedStrategy, fixed testSegmentDistributionUsingRoundRobinStrategy * to trigger CI build * Add documentation for the selection strategy configuration * to re trigger CI build * updated docs as per review comments, made LeastBytesUsedStorageLocationSelectorStrategy.getLocations a synchronzied method, other minor fixes * In checkLocationConfigForNull method, using getLocations() to check for null instead of directly referring to the locations variable so that tests overriding getLocations() method do not fail * Implementing review comments. Added tests for StorageLocationSelectorStrategy * Checkstyle fixes * Adding java doc comments for StorageLocationSelectorStrategy interface * checkstyle * empty commit to retrigger build * Empty commit * Adding suppressions for words leastBytesUsed and roundRobin of ../docs/configuration/index.md file * Impl review comments including updating docs as suggested * Removing checkLocationConfigForNull(), @NotEmpty annotation serves the purpose * Round robin iterator to keep track of the no. of iterations, impl review comments, added tests for round robin strategy * Fixing the round robin iterator * Removed numLocationsToTry, updated java docs * changing property attribute value from tier to type * Fixing assert messages |
