Issue # (if applicable)
None
Reason for this change
The
AWS::BedrockAgentCore::Memory L1resource now supportsStreamDeliveryResources.Description of changes
Added
StreamDeliveryContentTypeandStreamDeliveryContentLevelenumsAdded
StreamDeliveryContentConfigurationandStreamDeliveryResourceinterfaces.Both use arrays to match the CloudFormation schema, but currently enforce max length of 1 per the CFn spec.
(It seems odd that the CFn spec expects an array but caps it at max 1. I assumed this limit will be raised in a future update, so kept the array type to avoid a breaking change later.)
Added optional
streamDeliveryResourcesprop to MemoryProps (defaults to MEMORY_RECORDS + FULL_CONTENT when contentConfigurations is omitted)Added
addStreamDeliveryResource()method for post-instantiation configurationAdded
READMEdocumentation with code examplesDescribe any new or updated permissions being added
The Memory execution role is automatically granted the following permissions on each configured Kinesis Data Stream:
kinesis:ListShards,kinesis:PutRecord,kinesis:PutRecords(viastream.grantWrite())kinesis:DescribeStream(explicitly required per the setup guide Document)Description of how you validated changes
Added unit and integ test.
Note: The existing
integ.memory.tswas usingBedrockFoundationModel.ANTHROPIC_CLAUDE_3_5_SONNET_V1_0directly for custom memory strategies, which fails with "Bedrock model is not available in region" because AgentCore Memory requires a cross-region inference profile ID (e.g.us.anthropic.claude-sonnet-4-...confirmed at GUI).I fixed this by using
CrossRegionInferenceProfile.fromConfig()instead.Happy to split this change into a separate PR if preferred.
