Configuration
Environment variables
- AWS_SDK_DYNAMODB_MAX_ATTEMPTS: The maximum number of times requests that encounter retryable failures should be attempted for DynamoDB. Defaults to 3.
- AWS_SDK_S3_MAX_ATTEMPTS: The maximum number of times requests that encounter retryable failures should be attempted for S3. Defaults to 3.
- DYNAMO_BATCH_WRITE_COMMAND_CONCURRENCY: The number of concurrent batch write commands to DynamoDB. Defaults to 4 in an effort to leave plenty of DynamoDB write request capacity for the production load.
