# `RpcLoadBalancer.LoadBalancer.IndexRegistry`
[🔗](https://github.com/MikaAK/rpc_load_balancer/blob/main/lib/rpc_load_balancer/load_balancer/index_registry.ex#L1)

Assigns unique integer indices to arbitrary keys for a given cache.

Uses `Cache.PersistentTerm` for key-to-index mappings and `:atomics`
for a monotonic next-index counter per cache. Indices are zero-based
and never reused.
