Timestamp in Composite Key + +**Decision**: Include `starred_at` timestamp in both SK and GSI1SK + +**Rationale**: +- Enables natural chronological sorting +- Allows reverse sort for "newest first" without additional computation +- Prevents key collisions (multiple stars at same second is statistically insignificant) +- Supports time-range queries if needed in future + +**Trade-off**: Must query instead of GetItem to retrieve exact timestamp + +### 2. No Service Layer (Initially) + +**Decision**: Route directly from repository to entity, skip service layer + +**Rationale**: +- Simple CRUD with minimal business logic +- Validation is straightforward entity existence checks +- Reduces architectural overhead +- Service layer easily added later when notifications needed + +**Trigger for Service Layer Addition**: +- Star notifications implementation +- Star count aggregation across repositories +- Rate limiting per user +- Promotional logic (trending stars) + +### 3. Separate Queries for Get and Delete + +**Decision**: Query with begins_with pattern instead of GetItem for `get()` + +**Rationale**: +- DynamoDB GetItem requires exact key +- We don't store timestamp separately before delete +- Query with limit 1 is optimal for "does this star exist" checks +- Aligns with "check if starred" use case + +**Alternative Considered**: Store star without timestamp in SK, use separate timestamp attribute +- Rejected: Adds storage overhead and complexity +- Current approach cleaner with no downsides + +### 4. Idempotent Create and Delete + +**Decision**: Create returns existing if duplicate, delete succeeds if not found + +**Rationale**: +- Matches GitHub API behavior +- Safer for network retries +- Simplifies client code (no need for special error handling) +- Prevents cascading errors in dependent systems + +### 5. GSI1 for Reverse Access Pattern + +**Decision**: Dedicated GSI1 for "repository → stargazers" queries + +**Rationale**: +- Separate partition key (REPO#) from main table (ACCOUNT#) +- Enables efficient queries by repository without full table scan +- Allows independent sorting and pagination per repository +- Follows DynamoDB best practice for multiple access patterns + +**Cost**: Extra GSI but enables key access pattern (stargazers list) + +### 6. Validation via Transaction + +**Decision**: Validate user and repository existence within PutTransaction + +**Rationale**: +- Atomic operation - no race condition between validation and insert +- Single roundtrip to DynamoDB +- Leverages DynamoDB Toolbox transaction support +- Follows established pattern from IssueRepository + +**Flow**: +1. PutTransaction for star (with duplicate check) +2. ConditionCheck for user existence +3. ConditionCheck for repository existence +4. All succeed or all fail atomically + +## Dependencies + +### Internal Dependencies + +**User Entity** (`UserRecord`) +- **Reason**: Validate star references existing user +- **Status**: IMPLEMENTED +- **Used In**: `create()` method for ConditionCheck + +**Repository Entity** (`RepoRecord`) +- **Reason**: Validate star references existing repository +- **Status**: IMPLEMENTED +- **Used In**: `create()` method for ConditionCheck + +### External Dependencies + +**dynamodb-toolbox** (v2.7.1) +- **Usage**: Entity definition, key computation, DynamoDB operations +- **Specific Features**: + -
