Changelog

3.1.0 2023-09-07

Features

  • Support underscores in DynamoDB expression attribute names

Maintenance

  • Upgrade various library dependencies
  • A variety of fixes to the library's CI and testing

3.0.0 2023-07-24

Features

  • Updates to the AWS Cryptographic Material Providers Library for Java, a pivotal dependency of the this library, introduce Thread Safe Cryptographic Materials Caches (CMCs):
    • Storm Tracking Cache
      Safe for use in a multi threaded environment,
      tries to prevent redundant or overly parallel backend calls.
      See Spec changes for details.
    • Multi Threaded Cache
      Safe for use in a multi threaded environment,
      but no extra functionality
  • Examples for using the Enhanced Client via Lombok Annotation and TableSchemaBuilder
  • Detection of ignored DynamoDB Encryption Configuration Tags due to Nested Data Models
  • Multi Threading Example

BREAKING CHANGES

  • Updates to the AWS Cryptographic Material Providers Library for Java, a pivotal dependency of the this library, introduce the following breaking changes:
    • CMCs:
      • Original Cryptographic Materials Cache has been renamed to Single Threaded Cache
      • CreateCryptographicMaterialsCacheInput now ONLY accepts CacheType,
        which determines which, if any, of the three implemented CMCs will be returned.
      • The DefaultCache is StormTrackingCache
    • CreateAwsKmsHierarchicalKeyringInput:
      • no longer has a maxCacheSize field
      • now has an optional cache field for a CacheType
    • Hierarchical Keyring's Key Store:
      • The Hierarchical Keyring's Key Store's Data Structure has changed.
        As such, entries persisted in the Key Store with prior versions of this library are NOT compatible.
        Instead, we recommend Creating a new DynamoDB Table for this version of the Key Store.
      • The Key Store's CreateKeyInput now takes:
        • An Optional String branchKeyIdentifier
        • An Optional EncryptionContext encryptionContext
          • This encryptionContext will be added to the Encryption Context sent to KMS prefixed with aws-crypto-ec:
      • Creating a Key now also calls KMS:ReEncrypt
      • CreateKeyStore no longer creates a GSI
      • The Encryption Context used with KMS' GenerateDataKeyWithoutPlaintext no longer includes the discarded GSI's status.
      • More details about the Key Store's changes are available in our Specification:

Fix

  • With the Enhanced Client, Identify Only Index attributes for Sign Only, NOT all Key Attributes, such as Auto Generated Last Modified Time Stamp.

Maintenance

  • A variety of fixes to the libraries CI and testing

3.0.0-preview-2 2023-06-09
