📝 Walkthrough

Walkthrough

This change updates the logic in the create_concurrent_cursor_from_perpartition_cursor method within the ModelToComponentFactory class. Now, the method sets the use_global_cursor flag to True not only when the partition_router is an instance of GroupingPartitionRouter, but also when the component_definition dictionary contains a truthy "global_substream_cursor" key. Additionally, a new test was added to verify that when this flag is enabled, the state returned is global rather than per-partition. The _group_streams method in concurrent_declarative_source.py was also updated to include GlobalSubstreamCursor in its type checks. No changes were made to public interfaces or method signatures; the update is limited to internal logic and testing.

Changes

File(s)	Change Summary
airbyte_cdk/sources/declarative/parsers/model_to_component_factory.py	Modified the condition for setting use_global_cursor in create_concurrent_cursor_from_perpartition_cursor to also check for a "global_substream_cursor" key in the component definition.
airbyte_cdk/sources/declarative/concurrent_declarative_source.py	Expanded _group_streams method condition to include GlobalSubstreamCursor alongside PerPartitionWithGlobalCursor for stream slicer type checks.
unit_tests/sources/declarative/incremental/test_concurrent_perpartitioncursor.py	Added a new test test_given_global_state_when_read_then_state_is_not_per_partition verifying that enabling "global_substream_cursor" results in a global cursor state rather than per-partition states.

22-25: Looks good! The GlobalSubstreamCursor import is now included.

The addition of GlobalSubstreamCursor to the import statement is logical since it's needed for the type check update below. This is a necessary change to support the global substream cursor functionality.

367-369:

✅ Verification successful

Type check expanded to include GlobalSubstreamCursor, nice improvement!

The change to include GlobalSubstreamCursor in the instance check alongside PerPartitionWithGlobalCursor properly extends the functionality to support both cursor types for datetime-based cursor streams with partition routing.

This change aligns well with the updates to create_concurrent_cursor_from_perpartition_cursor method in the ModelToComponentFactory class that now considers the "global_substream_cursor" flag in component definitions.

GlobalSubstreamCursor coverage verified
I’ve confirmed that GlobalSubstreamCursor is exercised in unit_tests/sources/declarative/incremental/test_per_partition_cursor.py and unit_tests/sources/declarative/extractors/test_record_filter.py, and the new instance check in concurrent_declarative_source.py aligns with the CursorFactory updates. No further action appears necessary—wdyt?

There are 3 ways to chat with CodeRabbit:

‼️ IMPORTANT
Auto-reply has been disabled for this repository in the CodeRabbit settings. The CodeRabbit bot will not respond to your replies unless it is explicitly tagged.

• 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.
