Amazon QLDB

Ledger metadata only — the journal / Ion query data plane is not implemented. This is enough for Terraform/CDK templates that provision QLDB ledgers as part of broader stacks.

Operations

Operation	Method / Path
CreateLedger	POST /ledgers
DescribeLedger	GET /ledgers/{name}
ListLedgers	GET /ledgers
UpdateLedger	PATCH /ledgers/{name}
DeleteLedger	DELETE /ledgers/{name}
TagResource / UntagResource / ListTagsForResource	/tags/{resourceArn}

Behavior notes

• CreateLedger requires Name and PermissionsMode. DeletionProtection defaults to true.
• DeleteLedger rejects with ResourcePreconditionNotMetException while DeletionProtection is on — flip it via UpdateLedger first.
• State is ACTIVE immediately after Create; the emulator never spends time in CREATING / DELETING.
• Tag CRUD only persists tags on a known ledger — unknown ARNs return success silently.
