dev.event-sourcing-storage Calculator
Calculates event store storage growth, snapshot frequency requirement, and event replay time from event volume and schema. Event sourcing stores every state change as an immutable event — without periodic snapshots, replay time grows with history length and becomes impractical.
Inputs
Events Per Day
Reference formula or conversion factor shown for context.
Event Size Bytes
Reference formula or conversion factor shown for context.
Retention Days
Reference formula or conversion factor shown for context.
Snapshot Every N
Reference formula or conversion factor shown for context.
Results
total event storage (GB)
The combined total across all inputs and components.
daily event growth (GB)
The absolute increase in value over the period. Growth = final value minus initial value.
