PROFILE
Rama Krishnan Raghupathy
During May 2026, contributed a major feature to the Azure/azure-cosmos-dotnet-v3 repository by enhancing hierarchical partition key (HPK) functionality in Azure Cosmos DB. The work involved updating the backend C# implementation so that when '/id' is the last path in an HPK, the 'id' is automatically appended, allowing partition keys to span multiple physical partitions. This approach addressed scalability challenges by reducing hot-partition bottlenecks and improved throughput potential for HPK workloads. Additionally, the enhancement simplified SDK usage by removing redundancy in partition key definitions, streamlining common queries and aligning with performance and scale objectives for backend systems.

May 1, 2026May 2026 monthly recap for Azure/azure-cosmos-dotnet-v3. Delivered a major feature improvement: HPK Enhancement - appends id when '/id' is the last path in the hierarchical partition key (HPK). This enables HPK to span multiple physical partitions, increasing scalability and reducing hot-partition bottlenecks, while simplifying SDK usage by removing redundancy in partition key definitions. Implemented in commit 8bab2ecd018a62d3c3b4eae555906b36f36739b4 and referenced issue #5600. Impact includes higher throughput potential for HPK workloads, improved distribution of storage and RU/s, and smoother developer experience. This work aligns with performance/scale objectives and sets the stage for broader HPK adoption in customer scenarios.
