dev.infra-index-bloat Calculator
Calculates database index bloat percentage and the dead tuple ratio that triggers performance degradation in a cloud infrastructure and DevOps context. Postgres B-tree indexes bloat when rows are updated or deleted — bloat above 30% degrades index scan performance and triggers autovacuum more frequently.
Inputs
Live
Reference formula or conversion factor shown for context.
Dead
Reference formula or conversion factor shown for context.
Fill
A multiplier applied in the calculation.
Results
dead tuple ratio
The proportional relationship between two quantities.
vacuum needed
Sample size or count used in the calculation.
effective fill
Reference formula or conversion factor shown for context.
bloat (pages)
Table or index bloat -- wasted storage from dead rows not yet reclaimed by VACUUM. High bloat degrades query performance.
