Abstract
A disclosed configuration receives a first indication that a first transaction is committed to update a first subset of records in a data table at a first version to generate a second version of the data table and receiving a second indication to commit a second transaction to update a second subset of records in a data file of the data table at the first version. The configuration determines a logical prerequisite based on whether the first subset of records changes content of one or more records in the second subset of records and determining a physical prerequisite on whether the second subset of records corresponds to respective data records in data files of the second version of the data table. The configuration commits the second transaction to generate a third version of the data table by updating elements of the deletion vector if the prerequisites are satisfied.
