Hashstore Compaction Playground

Paste raw STBB text or enter ALIVE values manually. This page estimates how likely a log is to be chosen for compaction based on alive-fraction and probability-power, and it also shows the approximate rewrite target from rewrite-multiple.

Inputs

alive-fraction

probability-power

rewrite-multiple

Hashtable size per shard (GiB, optional)

ALIVE values

No STBB values extracted yet.

Formula

probability_factor = alive_fraction / (1 - alive_fraction) base_prob = probability_factor * (1 - x) / x y = base_prob ^ probability_power

Higher y means a log is more likely to be selected. The new pick chance % column is a simple normalized estimate from this model: it shows y × 100, capped at 100%. It is meant as an easy comparison aid, not as an exact Storj scheduler guarantee.
