Updated OrderByQueryRangeStrategy and ParallelQueryRangeStrategy to utilize PartitionRangeWithContinuationToken for improved handling of continuation tokens. - Removed legacy continuation token validation and parsing methods, simplifying the filterPartitionRanges method. - Enhanced TargetPartitionRangeManager to accept range-token pairs and additional query information. - Implemented partition split/merge detection in ParallelQueryExecutionContextBase, allowing for dynamic updates to continuation tokens based on partition topology changes. - Adjusted related interfaces and types to accommodate new structure for handling partition ranges and continuation tokens. - Updated unit tests to reflect changes in continuation token handling and ensure correct functionality. --- .../CompositeQueryContinuationToken.ts | 112 ++++-- .../ContinuationTokenManager.ts | 104 ++++++ .../OrderByQueryRangeStrategy.ts | 217 +++-------- .../ParallelQueryRangeStrategy.ts | 117 ++---- .../TargetPartitionRangeManager.ts | 66 ++-- .../TargetPartitionRangeStrategy.ts | 25 +- .../queryExecutionContext/documentProducer.ts | 2 +- .../orderByDocumentProducerComparator.ts | 4 +- .../parallelQueryExecutionContextBase.ts | 348 ++++++++++++------ .../pipelinedQueryExecutionContext.ts | 16 +- sdk/cosmosdb/cosmos/src/queryIterator.ts | 1 -
