[Source-mysql] : Implement WASS algo

[akashkulk]

Main changes here include :

1. CDK changes : Support for Initial load timeout utils, change in global state manager to support an edge case where the cdc state manager isn't propogating per-stream state from the initial load. This would result in data loss in the "second/WASS sync" case where the state emitted in the DBZ code path would incorrectly mark in progress streams as complete.
2. Main change in order of iterator execution is in MySqlInitialReadUtil from line 272, where are 3 cases : (i) First sync (no streams in flight for initial load) (ii) Fully incremental sync (all streams finished with initial load) and (iii) WASS sync (initial load not complete)
3. Timeout logic in MySqlInitialLoadRecordIterator to throw a transient error after timeout which can be configured in the spec

Tests
Most of the changes in the unit tests are to support the second sync (aka the WASS sync, where we read off the WAL and then transition to the initial snapshot). This can happen when

1. A new stream is added for the second sync. In this case, the WAL runs first and
2. A stream is partially completed - so the WAL runs first followed by initial sync

In these cases, the previous state messages were in this order as initial snapshots always ran before cdc loads
STATE_PK_LOAD_1, STATE_PK_LOAD2……, STATE_PK_LOAD_FINAL, STATE_CDC_LOAD

In the same WASS case, the state messages are :
STATE_CDC_LOAD, STATE_PK_LOAD_1, STATE_PK_LOAD2……, STATE_PK_LOAD_FINAL

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>.
  • 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 generate interesting stats about this repository and render them as a table.
  • @coderabbitai show all the console.log statements in this repository.
  • @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.

CodeRabbit Commands (invoked as PR comments)

• @coderabbitai pause to pause the reviews on a PR.
• @coderabbitai resume to resume the paused reviews.
• @coderabbitai review to trigger an incremental review. This is useful when automatic reviews are disabled for the repository.
• @coderabbitai full review to do a full review from scratch and review all the files again.
• @coderabbitai summary to regenerate the summary of the PR.
• @coderabbitai resolve resolve all the CodeRabbit review comments.
• @coderabbitai configuration to show the current CodeRabbit configuration for the repository.
• @coderabbitai help to get help.

Additionally, you can add @coderabbitai ignore anywhere in the PR description to prevent this PR from being reviewed.

CodeRabbit Configration File (.coderabbit.yaml)

• You can programmatically configure CodeRabbit by adding a .coderabbit.yaml file to the root of your repository.
• Please see the configuration documentation for more information.
• If your editor has YAML language server enabled, you can add the path at the top of this file to enable auto-completion and validation: # yaml-language-server: $schema=https://coderabbit.ai/integrations/schema.v2.json
