Positional Update Handling in Column Stores
Summary: Proposes Positional Delta Tree (PDT) for online updates in column stores while preserving read performance. PDT tracks tuple positions, not values, enabling fast updates and reduced I/O for read-only queries, outperforming traditional value-based differentials in TPC-H experiments.
