Ilaria Battiston, Lotte Felius, Sam Ansmink +2
We provide an evaluation of an analytical workload in a confidential computing environment, combining DuckDB with two technologies: modular columnar encryption in Parquet files (da…
OpenIVM: a SQL-to-SQL Compiler for Incremental Computations
Ilaria Battiston, Kriti Kathuria, Peter Boncz
This demonstration presents a new Open Source SQL-to-SQL compiler for Incremental View Maintenance (IVM). While previous systems, such as DBToaster, implemented computational funct…
