Abstract
A database system operates by: receiving a plurality of row data associated with a first data source; identifying a subset of row data from the plurality of row data that includes only ones of the plurality of row data that compare favorably to maintained row durability data; generating at least one page from ones of the plurality of row data included in the subset of row data; storing the at least one page in long term storage; generating updated row durability data indicating a least favorably ordered row number of a plurality of row numbers corresponding to the subset of row data based on storing the at least one page in long term storage; and updating the maintained row durability data to indicate the least favorably ordered row number of the updated row durability data.
