Walkthrough

The changes update the AWS package version and improve DynamoDB stream event processing. In the AWS package configuration file, the version is incremented. In the DynamoDB stream event module, the version is updated, a new _getNewShardIterator method is added, and the logic in the run method is adjusted to better handle shard iterators by conditionally updating them based on validity.

Changes

File(s)	Change Summary
components/aws/package.json	Updated package version of @pipedream/aws from 0.7.5 to 0.7.6.
components/aws/sources/.../new-dynamodb-stream-event.mjs	Updated module version from 0.0.2 to 0.0.3. Added a new method _getNewShardIterator called during deploy, modified run logic to use a fallback for shard iterator, and updated shard iterator setting to be conditional on a truthy value.

    %% Deployment phase
    E->>S: Call _getNewShardIterator (deploy hook)
    S-->>E: Return new shard iterator

    %% Run phase
    E->>S: Call _getShardIterator
    alt Result is null/undefined
        E->>S: Call _getNewShardIterator
        S-->>E: Return fallback shard iterator
    else Valid iterator obtained
        S-->>E: Return valid shard iterator
    end
    E->>E: Check if iterator is valid
    alt Valid iterator
        E->>E: Call _setShardIterator

Poem

I've hopped through code with clever flair,
Updating versions with utmost care.
A new shard method now takes the stage,
Stream iterators set, like a sage!
Hoppin' and codin'—a bunny's delight,
Cheers to changes that shine so bright!

🪧 Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
