Aeris filter

Aeris is an adaptive range-emptiness filter that extends partition fingerprints after database feedback identifies a false positive.

Its on-disk reverse map supplies keys for correction and selective rejuvenation during expansion. [1]

The target false-positive bound assumes a configured maximum range length; longer queries are supported without that same bound. [1]

The authors report 5.1 GB of reverse-map disk space in a WiredTiger experiment with 100 million 8-byte keys and 504-byte values. This auxiliary storage and its cache belong in the system budget; the measured overhead is workload-specific. [1]
