loadCache

clearCache

void clearCache()

getLastUpdatedMillis

default Long getLastUpdatedMillis(String key)

Returns when the cached value was last updated, in epoch milliseconds.

The optional background feature refresh interval uses this timestamp to decide whether cached features are fresh enough to skip a network refresh. Custom cache implementations may return null when timestamp tracking is unsupported or when the key does not exist; in that case the SDK treats cache freshness as unknown and performs the network refresh. Implementations should throw FeatureCacheException for real cache access failures.
