dev.perf-graphql-depth Calculator
Calculates GraphQL query depth, complexity score, and the risk of N+1 queries from a query structure in a application performance engineering context. GraphQL without depth limiting allows clients to construct deeply nested queries that cause O(n^depth) database queries — query complexity limits and DataLoader batching are essential.
Inputs
Depth
Vertical extent downward, or thickness of a layer. For tanks: affects pressure at the base (P = ρgh).
Breadth
Reference formula or conversion factor shown for context.
Res Ms
Duration of the process. Make sure units match the rate inputs (seconds, minutes, or hours).
Results
max nodes
Sample size or count used in the calculation.
complexity score
Algorithmic complexity class (e.g. O(n), O(n log n), O(n^2)). Determines how runtime or memory scales with input size.
resolver latency
Time from request initiation to response received. Composed of processing time, network round-trip, and queuing delay.
daily p99 budget
99th percentile latency -- only 1% of requests are slower. Captures tail latency that affects the worst-case user experience.
