- Optimized `ProcessPayment` in `WalletService` to reduce database round-trips from 2 to 1. - Replaced separate `SELECT EXISTS` check with `INSERT ... ON CONFLICT DO NOTHING`. - Used `RowsAffected()` to detect pre-existing transactions. - Reduces transaction window and contention in `SERIALIZABLE` isolation mode. How to test: Environment: Local development environment with Go 1.26. 1. Navigate to `back-end` directory. 2. Run `go test -v ./internal/service/...`. 3. Verify that all tests pass, especially the idempotency logic in `ProcessPayment`. Expected result: Functionality remains identical, but database interaction for idempotency is combined with insertion, leading to ~50% reduction in round-trip latency for new payments.

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job! For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with New to Jules? Learn more at jules.google/docs.

- Optimized `ProcessPayment` in `WalletService` to reduce database round-trips from 2 to 1. - Replaced separate `SELECT EXISTS` check with `INSERT ... ON CONFLICT DO NOTHING`. - Used `RowsAffected()` to detect pre-existing transactions. - Reduces transaction window and contention in `SERIALIZABLE` isolation mode. - Fixed CI by updating `.github/workflows/backend-ci.yml` to use Go 1.26 (matching `go.mod`). - Configured `golangci-lint-action` with `install-mode: go` to ensure compatibility with Go 1.26. How to test: Environment: Local development environment with Go 1.24+ (targets 1.26). 1. Navigate to `back-end` directory. 2. Run `go test -v ./internal/service/...`. 3. Verify that all tests pass, especially the idempotency logic in `ProcessPayment`. 4. Verify GitHub Actions once pushed. Expected result: Functionality remains identical, but database interaction for idempotency is combined with insertion, leading to ~50% reduction in round-trip latency for new payments. CI passes with correct Go version. Co-authored-by: MethasMP <89190477+MethasMP@users.noreply.github.com>
- Optimized `ProcessPayment` in `WalletService` to reduce database round-trips from 2 to 1. - Replaced separate `SELECT EXISTS` check with `INSERT ... ON CONFLICT DO NOTHING`. - Used `RowsAffected()` to detect pre-existing transactions. - Reduces transaction window and contention in `SERIALIZABLE` isolation mode. - Fixed CI by updating `.github/workflows/backend-ci.yml` to use Go 1.26 and golangci-lint-action@v6. - Configured `golangci-lint-action` with `install-mode: go` to ensure it is built with the correct Go version. How to test: 1. Navigate to `back-end` directory. 2. Run `go test -v ./internal/service/...`. 3. Verify that all tests pass. 4. Verify GitHub Actions with golangci-lint-action@v6. Expected result: Performance optimization implemented successfully. CI passes by using a newer action version that supports `install-mode: go` correctly for Go 1.26.

⚡ Bolt: optimize ProcessPayment round-trips
💡 What:
Optimized the
ProcessPaymentfunction in the GoWalletServiceto consolidate the idempotency check and record insertion into a single database operation.🎯 Why:
The original implementation performed a
SELECT EXISTSquery followed by anINSERTstatement within aSERIALIZABLEtransaction. This pattern:SERIALIZABLEmode as it raises the risk of serialization failures under high concurrency.📊 Impact:
🔬 Measurement:
Verified via
go test -v ./internal/service/...to ensure correctness. Performance gain demonstrated via local benchmarking of database round-trip reduction.BOLT'S JOURNAL:
