Overview

This class is part of a private API. You should avoid using this class if possible, as it may be removed or be changed in the future.

Assembles a StorageSet from a backend, selecting windowed or unbounded metrics.

StorageSetBuilder is the single point where the windowed/unbounded decision is made. All other storage components (state, recovery lock, recovery metrics) are backend-specific but mode-independent.

Examples:

Windowed metrics (error rate tracking)

builder = StorageSetBuilder.new(backend: redis_backend, windowed: true)
storage = builder.build
storage.metrics_store #=> FailSafe<WindowMetrics>

Unbounded metrics (consecutive error tracking)

builder = StorageSetBuilder.new(backend: memory_backend, windowed: false)
storage = builder.build
storage.metrics_store #=> UnboundedMetrics
