Hello @rahul2393, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
Summary of Changes
Hello! Gemini or gemini-code-assist here, providing a summary of this pull request.
This pull request updates the existing spanner_database_add_split_points.go sample. The primary goal is to enhance the sample by demonstrating how to add a split point with the ExpireTime field set. Previously, the sample only covered adding split points without specifying an expiration. This change introduces a new split point definition that includes setting the ExpireTime to 24 hours in the future, offering a more comprehensive example of the AddSplitPoints API functionality.
Highlights
- Sample Enhancement: The
spanner_database_add_split_points.gosample is updated to show a more complete use case. - Demonstrate ExpireTime: A new split point is added to specifically illustrate how to set the
ExpireTimefield. - Future Expiration: The sample now includes setting an expiration time for a split point to 24 hours from the current time.
Changelog
- spanner/spanner_snippets/spanner/spanner_database_add_split_points.go
- Added imports for the
timepackage andgoogle.golang.org/protobuf/types/known/timestamppbto handle time values and protobuf timestamps. - Created a new
SplitPoints_Keyobject (splitTableKeyWithExpire) with the key value "30". - Defined a new
SplitPointsobject (splitForTableWithExpire) targeting the "Singers" table, using the new key and setting theExpireTimetotime.Now().Add(24 * time.Hour). - Included the newly created
splitForTableWithExpireobject in theSplitPointsslice passed to theAddSplitPointsRequest. - Added comments explaining the behavior and constraints of the
ExpireTimefield.
- Added imports for the

Code Review
The changes successfully update the sample to include adding a split point with the ExpireTime set, addressing the issue mentioned in the pull request description. The code is clear, follows the existing pattern of the sample, and correctly utilizes the necessary types and functions from the Spanner client library and protobufs. The addition of comments explaining the ExpireTime field is helpful.
Summary of Findings
- Test coverage detail: The existing integration test
TestAddSplitPointsSampleasserts that the output contains "Added split points". While this confirms the function ran without error, it doesn't specifically verify that the split point withExpireTimewas included in the request or that theExpireTimewas set correctly. For a sample, this level of testing might be acceptable, but for production code, more specific assertions would be beneficial. This was not included as a review comment due to the severity settings. - Output message verbosity: The sample prints the entire response object using
fmt.Fprintf(w, "Added split points %s", res). While this shows the full response, it might be overly verbose for a simple sample output. A more concise message confirming the action might be preferable. This was not included as a review comment due to the severity settings.
Merge Readiness
The code changes are well-implemented and directly address the stated objective. I did not find any critical, high, or medium severity issues in the modified code. The pull request appears ready to be merged. Please note that I am unable to directly approve the pull request; other reviewers should review and approve this code before merging.
