A persistent distributed database system is disclosed that partitions a database structure into a plurality of partitions to optimize repeated analytics that are executed on the database structure. A repeated analytic is partitioned into sub-analytics that are executed on the database partitions, and upon repeated executions, sub-analytics are only repeated upon database partitions that have been updated since the previous execution. This drastically reduces the time to repeat execution of a repeated analytic, and frees up resources that could be better spent on other processes.
