June 2025: Focused on stabilizing cache invalidation in hypermodeinc/dgraph. Delivered a critical bug fix to ensure single cache-clearing operation, preventing double-clearing of keys and reducing risk of inconsistencies. This change improves data freshness, reliability, and overall system stability, with traceable deployment in the codebase.

In May 2025, the team focused on strengthening data integrity and mutation reliability in hypermodeinc/dgraph. A critical bug affecting reverse edges with count indexes during rapid set/delete mutations was fixed, and a verification test was added to ensure long-term correctness. The changes improve consistency under high mutation load and reduce the risk of data loss in live deployments.

January 2025 performance summary for hypermodeinc/dgraph: Focused on stabilizing the cleanup/rollup workflow by diagnosing and fixing a critical time-unit mismatch in the incrRollupi cleanup path, preventing data loss and improving data integrity across rollups. The change aligns cleanupTick time units with doRollup logic (Unix seconds vs UnixNano), reducing the risk of erroneous deletions during cleanup cycles and enabling safer, more predictable time-series processing.
