Abstract
A two dimensional bit array is maintained to keep track of the location of data records in a log file that is organized as a plurality of log segments, each comprising a plurality of data records. The data records are indexed in the log file according to randomized unique ids. Each column of the two dimensional bit array represents a Bloom filter corresponding to a log segment of the log file such that, given a particular randomized unique id, log segments that may contain the data record corresponding to the particular randomized unique id can be efficiently identified by utilizing Bloom filter techniques to analyze the columns of the two dimensional bit array.
