Module dynamodb_checkpointer 

DynamoDB-backed checkpointer implementation for AWS deployments.

This checkpointer stores agent state in Amazon DynamoDB, providing:

• Fully managed, serverless persistence
• Automatic scaling and high availability
• Global table support for multi-region deployments
• Pay-per-request pricing with on-demand mode

Table Schema

The checkpointer expects a DynamoDB table with the following schema:

• Primary Key: thread_id (String)
• Attributes:
  • state (Map/JSON) - The serialized agent state
  • updated_at (String) - ISO 8601 timestamp
  • ttl (Number, optional) - Unix epoch for automatic expiration

Setup

Create the table using AWS CLI:

aws dynamodb create-table \
  --table-name agent-checkpoints \
  --attribute-definitions AttributeName=thread_id,AttributeType=S \
  --key-schema AttributeName=thread_id,KeyType=HASH \
  --billing-mode PAY_PER_REQUEST

Or use Terraform (see deploy/modules/dynamodb/).
