	// SweepInterval is the rate at which to run the garabage collection on stale

	// will likely reduce performance and increase lock contention. Setting this
	// to a high value will maximum throughput, but will increase the memory
	// footprint. This can be tuned in combination with SweepMinTTL to control how
	// long stale entires are kept. The default value is 6 hours.

	// SweepMinTTL is the minimum amount of time a session must be inactive before
	// clearing it from the entries. There's no validation, but this should be at
	// least as high as your rate limit, or else the data store will purge records
	// before they limit is applied. The default value is 12 hours.

	// sync.Map, which does not support pre-sizing.
