Abstract
The long-lived and recently modified (LLRM) partitioning is a system and method for partitioning slowly changing aged data for a given year into one long-lived partition (LLP) and multiple recently modified partitions (RMP) where the RMP corresponds to a time period of a first time granularity. Each record has a start and end time to indicate its lifetime. A record in a RMP is modified at a timepoint corresponding to the time period of a RMP. RMP records can be sampled every second, minute, hour or day. The LLP holds records whose lifetime is greater than the time period of a first time granularity. Queries pertaining to a given timepoint is performed on data that is a union of the LLP and the RMP pertaining to that timepoint instead of the unpartitioned table thus leading to shorter query processing time and better utilization of memory storage.
