neumann_shell Benchmarks

The neumann_shell crate provides the interactive CLI with readline, WAL-backed durability, and snapshot support.

Overview

Shell benchmarks measure command parsing, dispatch overhead, and WAL replay performance.

Expected Performance Characteristics

Operation	Complexity	Notes
Command parse + dispatch	O(query)	Dominated by query router
WAL append	O(1)	Single append per command
WAL replay	O(n)	Linear in log entry count
Snapshot save	O(keys)	Serializes full store state
Snapshot load	O(keys)	Deserializes store state
