nodedb-mem

Per-engine memory governor backed by jemalloc arenas

Pins each Data Plane core to a dedicated jemalloc arena, enforces per-engine memory budgets via a MemoryGovernor::reserve() API, and exposes pressure metrics. Eliminates allocator lock contention across TPC cores.

Features

• jemalloc (off by default): arena pinning and allocator stats. Enable it only in a binary that installs jemalloc as its global allocator. Without it, budgets work unchanged, arena pinning is a no-op, and no jemalloc C library is linked.

Status

Pre-1.0. APIs may change between minor versions until 1.0. See the workspace README.md for the full project overview and the GitHub release notes for per-version changes.
