dev.session-storage-sizing Calculator
Calculates session storage size requirements from session count, session data size, and TTL-based eviction rate. Redis session storage at 1KB per session handles 1M concurrent sessions in 1GB of memory — significantly more efficient than database-backed sessions.
Inputs
Dau
Reference formula or conversion factor shown for context.
Session Kb
Reference formula or conversion factor shown for context.
Session Hrs
Length of time the process lasts. Ensure units are consistent with rate inputs.
Peak Multiplier
Reference formula or conversion factor shown for context.
Results
peak concurrent sessions
Electric charge flow rate (A). Governs wire sizing — too much current causes dangerous heating. Fuses protect circuits from overcurrent.
Redis memory needed (GB)
Sample size or count used in the calculation.
DAU
Reference formula or conversion factor shown for context.

Gratuity amount — the suggested amount to add to the bill as a service tip.
Redis instances (16GB each)
Sample size or count used in the calculation.
