利用Lambda与DynamoDB Streams构建动态仪表板:第一部分原文链接:
DynamoDB update streams can include new, old, or both types of data when an item is created or modified. For this case, choose New and old images. Setting up the IAM policy and role Now, create an IAM policy and the role that references that policy, to allow...
To use zero-ETL integration, you will first need to enablepoint-in-time recovery (PITR)on your table. Once PITR is enabled, select the ‘new and old images’ option for your DynamoDB streams. The integration operates without impacting DynamoDB table throughput, providing a safe...
AWS Lambda based incremental backup The DynamoDB Stream StreamViewType needs to be one of NEW_IMAGE, NEW_AND_OLD_IMAGES, or KEYS_ONLY. Note that DynamoDB Streams does not support encryption at rest. const Backup = require('dynamodb-backup-restore').Backup; module.exports.handler = (event,...
stream_view_type- (Optional) When an item in the table is modified, StreamViewType determines what information is written to the table’s stream. Valid values are KEYS_ONLY, NEW_IMAGE, OLD_IMAGE, NEW_AND_OLD_IMAGES. local_secondary_index- (Optional, Forces new resource) Describe an LSI ...
DynamoDB streamsguarantee"at-least-once" delivery, which means your Lambdacouldreceive the same event twice. Plan for that by building idempotency into your Lambda functions or downstream services. 7. When you need to add a new access pattern, "You don't necessarily have to remodel everything...
