[FEATURE]: Design Asynchronous Non-Blocking Cache Checkpointer Utilizing Lock-Free Ring Buffers

Problem

Writing high-frequency context state snapshot frames to traditional database engines triggers heavy thread contention and memory locking states, causing severe processing tail latencies that degrade overall sub-2ms network routing performance.

Proposed Solution

Implement a high-throughput stateless checkpointer under internal/storage/ring_buffer.go:

1. The Lock-Free Atomic Ring Array: Deploy circular allocation buffer pools controlled via native Go pointer atomic switches (sync/atomic) to store incremental bit snapshot arrays asynchronously without thread blockages.
2. Lazy Storage Evacuation: Flush memory-mapped state frames sequentially to local disk sectors or cloud object arrays using background worker routines (goroutines) running outside the critical request path.

Use Case

Maintains an unassailable performance profile. It demonstrates to core technical reviewers that FaultPlane scales state resilience seamlessly across massive high-density multi-tenant workloads.

Start by reading internal/storage/ring_buffer.go and tracing how context state snapshot frames currently reach storage. The issue provides no test or benchmark entry point; done would require an agreed asynchronous checkpointer design covering the atomic ring buffer and background evacuation without blocking the request path.
