Known gaps
  • Cluster.Status is always "available" immediately on CreateCluster; real AWS transitions creating -> available. Not fixed (broad behavioral change, no bd issue filed yet).
  • DescribeClusters hand-rolls its own NextToken cursor loop in handler.go instead of using the paginateItems helper (or pkgs/page) every other list op in this file uses. Functionally equivalent, just inconsistent; not fixed (style/dedup only, no wire-visible bug).
  • writeBackendError's HTTP status codes (404/409/400 by category) were left as-is rather than aligned to AWS's uniform 400-for-all-client-faults convention for awsjson1.1 FaultClient errors -- would need re-verification against 59 existing status-code assertions plus live-AWS confirmation before changing; the __type field (which the SDK actually uses to resolve typed errors) is now correct regardless.
Deferred
  • Byte-for-byte wire audit of nested Shard/Node objects beyond the timestamp field (shardObject/nodeObject in handler.go's buildShards) -- spot-checked only, CreateTime already correct.
  • MultiRegionCluster full lifecycle wire shape beyond the fields already checked (no per-region-cluster nested list verified against real MultiRegionCluster type).
  • DescribeReservedNodesOfferings/PurchaseReservedNodesOffering pricing-field completeness (RecurringCharges shape) beyond the StartTime fix.

type InMemoryBackend 

type InMemoryBackend struct {
	// contains filtered or unexported fields
}

InMemoryBackend is the in-memory implementation of StorageBackend.

multiRegionClusters, multiRegionParameterGroups, and serviceUpdates are partition-scoped (like AWS) and therefore NOT region-nested; they are registered on registry so Reset/Snapshot/Restore collapse to one Registry call each. Every other resource is nested per-region (map[string]*store.Table[T], outer key is region) via the lazy "*Store" accessors below. Per-region tables are deliberately NOT registered on registry because the set of regions is only known at runtime -- see store_setup.go and persistence.go for how they are (de)serialized instead.

arnToResource and events are left as plain maps: arnToResource's value (resourceRef) has no key of its own to feed a Table's keyFn (the ARN is the map key, not a value field), and events is slice-valued (map[string][]*Event), neither of which store.Table can represent.
