2019/09/09 - Amazon QLDB - 15 new api methods
Changes (New Service) Amazon QLDB is a fully managed ledger database that provides a transparent, immutable, and cryptographically verifiable transaction log owned by a central trusted authority. Amazon QLDB is a new class of serverless database that eliminates the need to engage in the complex development effort of building your own ledger-like applications and it automatically scales to support the demands of your application. Introduces Amazon QLDB API operations needed for managing Amazon QLDB ledgers. This includes the ability to manage Amazon QLDB ledgers, cryptographically verify documents, and export the journal in a ledger.
Removes one or more tags from a specified Amazon QLDB resource. You can specify up to 50 tag keys to remove.
