* #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
* Rename partition spec fields
Rename partition spec fields to be consistent across the various types
(hashed, single_dim, dynamic). Specifically, use targetNumRowsPerSegment
and maxRowsPerSegment in favor of targetPartitionSize and
maxSegmentSize. Consistent and clearer names are easier for users to
understand and use.
Also fix various IntelliJ inspection warnings and doc spelling mistakes.
* Fix test
* Improve docs
* Add targetRowsPerSegment to HashedPartitionsSpec
