Walkthrough

This set of changes removes several partition-related utility methods (containsPartitions, allPartitions, and related test cases) from the codebase. It updates partition retrieval logic in partition checks and test cases to use the partitions method directly, with added table reachability checks. The return type of parseHiveStylePartition is modified to preserve order and duplicates, and downstream code is updated to convert its output to a map as needed. Additionally, methods for creating "latest label" views and mappings are deleted, along with their usages and corresponding tests.

Poem

Out with partitions, old code swept away,
No more latest labels to keep at bay.
Utilities trimmed, the logic now neat,
Parsing with order, no duplicate defeat.
Refactored and tested, the suite feels light—
Code spring cleaning done just right!

🪧 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.

1016-1022: Improved partition checking with reachability guard

Enhanced implementation that first verifies if the table exists before attempting to check partitions.

Consider adding a comment explaining the reachability check's purpose to improve code maintainability.

+ // Check if table exists before attempting to retrieve partitions
  val containsSpec = if (tableUtils.tableReachable(tbl)) {

7-7: Consolidated import statements - good cleanup

Combining related Google Cloud Hadoop imports improves readability.


104-104: Updated to use partitions method instead of removed allPartitions

Correctly adapted test to use the remaining partition retrieval method.


114-114: Updated to use partitions method instead of removed allPartitions

Correctly adapted test to use the remaining partition retrieval method.

spark/src/main/scala/ai/chronon/spark/catalog/Format.scala (2)

90-90: Changed return type to preserve order and allow duplicates

Method now returns List[(String, String)] instead of Map[String, String] to maintain the original order of partition components.


97-97: Updated to return list instead of map

Changed .toMap to .toList to align with the new return type.

spark/src/main/scala/ai/chronon/spark/catalog/Hive.scala (1)

23-23: Added explicit map conversion to handle the changed return type

Added .toMap to convert the list of tuples returned by Format.parseHiveStylePartition to a map, maintaining compatibility with existing code.
