ExperimentalOptional Readonly ExperimentalmaxOptional Readonly ExperimentalmaxMaximum retained entries; the oldest is evicted first.
Optional Readonly ExperimentalnowOptional Readonly ExperimentalonReceives every miss, stale read, refusal, and storage failure. Must not throw.
Optional Readonly ExperimentalquotaByte quota across stored envelopes.
Optional Readonly ExperimentalserializationBounds applied to every serialize and deserialize this store performs.
Optional Readonly ExperimentaltelemetryOptional observer for this store. Off by default, and independent of
ColumnarBatchCacheOptions.onDiagnostic: a caller already using the
callback keeps it, and a caller wiring the SDK's telemetry seam sees the
same operation and reason discriminants on identity-bound columnar-cache-read
and columnar-cache-write spans.
Maximum entry age before a read reports stale.
