ZIP: Lazy Imputation during Query Processing
Summary: ZIP makes relational operators imputation-aware at query time, using a cost-based decide-to-impute-or-defer policy while guaranteeing results equivalent to eager (pre-query) imputation. Key techniques: outer-join execution to preserve NULLs and a Bloom-filter index; yields 10–25× speedups over ImputeDB and up to 19,607× vs. offline imputation.
