Zusammenfassung:Disclosed herein are system, method, and computer program product embodiments for bloom filter versioning. A request to add a new value to a first bitmap is received, wherein the first bitmap includes a bit sequence corresponding to a most recently added value. It is determined that the first bitmap has exceeded a threshold. A second bitmap is generated, the second bitmap including more bits than the first bitmap. The first bitmap is deleted based upon a determination that a number of readers accessing the first bitmap is zero.
