+
+## Overview
+
+The SIDX mock implementation provides three main components:
+
+- **MockSIDX**: Complete in-memory implementation of the main SIDX interface
+- **Mock Components**: Individual mocks for Writer, Querier, Flusher, and Merger interfaces
+- **Integration Test Framework**: Comprehensive testing harness with scenarios, benchmarks, and stress tests
+
+### Key Features
+
+- ✅ **Thread-safe operations** with proper synchronization
+- ✅ **Configurable behavior** including delays, error injection, and resource limits
+- ✅ **Realistic simulation** of performance characteristics
+- ✅ **Memory profiling** and performance measurement
+- ✅ **Comprehensive testing** with 100+ test cases
+- ✅ **Easy integration** with existing BanyanDB patterns
+
+## Mock Components
+
+### MockSIDX - Main Interface Implementation
+
+The `MockSIDX` provides a complete in-memory implementation of the SIDX interface:
+
+```go
+// Create with default configuration
+mockSIDX := NewMockSIDX(DefaultMockConfig())
+
+// Create with custom configuration
+config := MockConfig{
+ WriteDelayMs: 5, // Simulate 5ms write latency
+ QueryDelayMs: 2, // Simulate 2ms query latency
+ ErrorRate: 0, // No error injection
+ MaxElements: 10000, // Element limit
+ EnableStrictValidation: true, // Enable validation
+}
+mockSIDX := NewMockSIDX(config)
+```
+
+### Mock Component Suite
+
+The `MockComponentSuite` provides individual component implementations:
+
+```go
+// Create suite with default configurations
+suite := NewMockComponentSuite()
+
+// Create suite with custom configurations
+suite := NewMockComponentSuiteWithConfigs(
+ writerConfig, querierConfig, flusherConfig, mergerConfig)
+
+// Access individual components
+writer := suite.Writer
+querier := suite.Querier
+flusher := suite.Flusher
+merger := suite.Merger
+```
+
+### Integration Test Framework
+
+The framework provides comprehensive testing capabilities:
+
+```go
+// Create framework with mock implementations
+framework := NewIntegrationTestFramework(DefaultFrameworkConfig())
+
+// Run all tests (scenarios + benchmarks + stress tests)
+results, err := framework.RunAll(ctx)
+
+// Run individual test types
+scenarioResults, err := framework.RunScenarios(ctx)
+benchmarkResults, err := framework.RunBenchmarks(ctx)
+stressResults, err := framework.RunStressTests(ctx)
+```
+
+## Quick Start Guide
+
+### Basic Write-Read Workflow
+
+```go
+package main
+
+import (
+ "context"

+ result := make([]byte, 8)
+ for i := 0; i < 8; i++ {
+ result[7-i] = byte(val >> (8 * i))
+ }
+ return result

+```
+
+### Component Integration Example
+
+```go
+func ExampleComponentIntegration() {
+ ctx := context.Background()
+
+ // Create component suite

+ {SeriesID: 1, Key: 101, Data: []byte("data2")},
+ }
+
+ err := suite.Writer.Write(ctx, writeReqs)

+ if err != nil {
+ panic(err)
+ }
+
+ err = suite.Merger.Merge()
+ if err != nil {
+ panic(err)
+ }
+}
+```
+
+## Integration Examples
+

+
+```go
+// Example: Using MockSIDX in stream module tests
+func TestStreamWithMockSIDX(t *testing.T) {
+ // Create mock SIDX for testing
+ mockSIDX := sidx.NewMockSIDX(sidx.MockConfig{
+ WriteDelayMs: 1, // Fast writes for testing
+ QueryDelayMs: 1, // Fast queries for testing
+ ErrorRate: 0, // No errors during testing
+ MaxElements: 1000,
+ })
+ defer mockSIDX.Close()
+
+ // Use mockSIDX in your stream implementation
+ streamImpl := &StreamImplementation{
+ sidx: mockSIDX,
+ }
+
+ // Test stream operations
+ // ... your test code here
+}
+```
+
+### Integration with Measure Module
+
+```go
+// Example: Using mock components in measure module
+func TestMeasureWithMockComponents(t *testing.T) {
+ suite := sidx.NewMockComponentSuite()
+
+ // Configure for measure-specific testing
+ suite.Writer.SetConfig(sidx.MockWriterConfig{
+ DelayMs: 0, // No delay for fast tests
+ MaxElements: 10000, // Large capacity for measure data
+ SortElements: true, // Ensure sorting for measure queries
+ EnableValidation: true, // Validate measure data
+ })
+
+ measureImpl := &MeasureImplementation{
+ writer: suite.Writer,
+ querier: suite.Querier,
+ flusher: suite.Flusher,
+ merger: suite.Merger,
+ }
+
+ // Test measure operations
+ // ... your test code here
+}
+```
+
+### Custom Test Scenarios
+
+```go
+// Example: Creating custom test scenarios
+func ExampleCustomScenarios() {
+ framework := sidx.NewIntegrationTestFramework(sidx.DefaultFrameworkConfig())
+
+ // Register custom scenario
+ customScenario := sidx.TestScenario{
+ Name: "HighVolumeWrites",
+ Description: "Test high-volume write scenario",
+ Setup: func(ctx context.Context, framework *sidx.IntegrationTestFramework) error {
+ // Setup high-volume test data
+ return nil
+ },
+ Execute: func(ctx context.Context, framework *sidx.IntegrationTestFramework) error {
+ // Execute high-volume writes
+ for i := 0; i < 10000; i++ {
+ reqs := framework.GenerateTestData(1, 100)
+ err := framework.GetSIDX().Write(ctx, reqs)
+ if err != nil {
+ return err
+ }
+ }
+ return nil
+ },
+ Validate: func(ctx context.Context, framework *sidx.IntegrationTestFramework) error {

+ if err != nil {
+ return err
+ }
+ if stats.ElementCount < 100000 {
+ return fmt.Errorf("expected at least 100000 elements, got %d", stats.ElementCount)
+ }
+ return nil
+ },
+ }
+
+ framework.RegisterScenario(customScenario)
+
+ // Run custom scenario
+ results, err := framework.RunScenarios(context.Background())
+ if err != nil {
+ panic(err)
+ }
+
+ for _, result := range results {
+ fmt.Printf("Scenario %s: Success=%v, Duration=%v\n",
+ result.Name, result.Success, result.Duration)
+ }
+}
+```
+
+## Configuration Options
+
+### MockSIDX Configuration
+
+```go
+type MockConfig struct {
+ WriteDelayMs int // Artificial write delay (0-1000ms)
+ QueryDelayMs int // Artificial query delay (0-1000ms)
+ FlushDelayMs int // Artificial flush delay (0-1000ms)
+ MergeDelayMs int // Artificial merge delay (0-1000ms)
+ ErrorRate int // Error injection rate (0-100%)
+ MaxElements int // Maximum elements to prevent OOM
+ EnableStrictValidation bool // Enable validation checks
+}
+
+// Default configuration for most use cases
+config := DefaultMockConfig() // Returns sensible defaults
+
+// Performance testing configuration
+config := MockConfig{
+ WriteDelayMs: 0, // No artificial delays
+ QueryDelayMs: 0,
+ ErrorRate: 0, // No error injection
+ MaxElements: 100000,
+}
+
+// Error testing configuration
+config := MockConfig{
+ ErrorRate: 10, // 10% error rate
+}
+
+// Slow operation simulation
+config := MockConfig{
+ WriteDelayMs: 50, // 50ms write latency
+ QueryDelayMs: 20, // 20ms query latency
+}
+```
+
+### Component Configuration
+
+```go
+// Writer configuration
+writerConfig := MockWriterConfig{
+ DelayMs: 5, // 5ms write delay
+ ErrorRate: 0, // No errors
+ MaxElements: 1000, // Element limit
+ EnableValidation: true, // Validate requests
+ SortElements: true, // Sort elements by SeriesID/Key
+}
+
+// Querier configuration
+querierConfig := MockQuerierConfig{
+ DelayMs: 2, // 2ms query delay
+ ErrorRate: 0, // No errors
+ EnableValidation: true, // Validate requests
+ MaxResultSize: 100, // Max results per batch
+}
+
+// Flusher configuration
+flusherConfig := MockFlusherConfig{
+ DelayMs: 10, // 10ms flush delay
+ ErrorRate: 0, // No errors
+ SimulateWork: true, // Simulate actual work
+}
+
+// Merger configuration
+mergerConfig := MockMergerConfig{
+ DelayMs: 20, // 20ms merge delay
+ ErrorRate: 0, // No errors
+ SimulateWork: true, // Simulate actual work
+ ConsolidationRatio: 0.7, // 70% size reduction after merge
+}
+```
+
+### Framework Configuration
+
+```go
+frameworkConfig := FrameworkConfig{
+ EnableVerboseLogging: true, // Detailed logging
+ MaxConcurrency: runtime.NumCPU() * 2, // Concurrent operations
+ DefaultTimeout: 30 * time.Second, // Operation timeout
+ BenchmarkDuration: 10 * time.Second, // Benchmark duration
+ StressDuration: 30 * time.Second, // Stress test duration
+ EnableMemoryProfiling: true, // Memory usage tracking
+}
+```
+
+## Testing Scenarios
+
+### Built-in Scenarios
+
+The framework includes several built-in scenarios:
+
+1. **BasicWriteRead**: Write elements and read them back
+2. **FlushAndMerge**: Test flush and merge operations
+3. **LargeDataset**: Handle large datasets efficiently
+
+### Built-in Benchmarks
+
+1. **WritePerformance**: Measure write throughput and latency
+2. **QueryPerformance**: Measure query throughput and latency
+
+### Built-in Stress Tests
+
+1. **ConcurrentWrites**: Test concurrent write performance and stability
+2. **MixedOperations**: Test mixed read/write operations under load
+
+### Running Tests
+
+```go
+// Run all tests
+framework := sidx.NewIntegrationTestFramework(sidx.DefaultFrameworkConfig())
+results, err := framework.RunAll(ctx)
+
+// Access results
+scenarioResults := results["scenarios"].([]sidx.ScenarioResult)
+benchmarkResults := results["benchmarks"].(map[string]sidx.BenchmarkResult)
+stressResults := results["stress_tests"].(map[string]sidx.StressTestResult)
+
+// Print results
+for _, scenario := range scenarioResults {
+ fmt.Printf("Scenario %s: %v (%v)\n",
+ scenario.Name, scenario.Success, scenario.Duration)
+}
+
+for name, benchmark := range benchmarkResults {
+ fmt.Printf("Benchmark %s: %.2f ops/sec (P95: %v)\n",
+ name, benchmark.OperationsPerSecond, benchmark.LatencyP95)
+}
+```
+
+## Performance Characteristics
+
+### Expected Performance (Mock Implementation)
+
+| Operation | Throughput | Latency | Notes |
+|-----------|------------|---------|-------|
+| Write | >10,000 elem/sec | <1ms P95 | In-memory storage |
+| Query | >50,000 results/sec | <1ms P95 | Linear search |
+| Flush | ~100ms | N/A | Simulated disk I/O |
+| Merge | ~200ms | N/A | Simulated consolidation |
+
+### Memory Usage
+
+- **Element storage**: ~200 bytes per element (including tags)
+- **Query overhead**: ~50 bytes per query result
+- **Framework overhead**: ~1MB base memory usage
+
+### Concurrency
+
+- **Thread-safe**: All operations are thread-safe
+- **Recommended concurrency**: Up to 100 concurrent operations
+- **Lock contention**: Minimal with read-write locks
+
+## Troubleshooting
+
+### Common Issues
+
+#### 1. Query Returns No Results
+
+**Problem**: Query returns empty results even after writing data.
+
+**Solution**:
+```go
+// Ensure you're using the correct series name
+// MockSIDX stores data with keys like "series_1", "series_2", etc.
+queryReq := QueryRequest{
+ Name: "series_1", // Must match the naming pattern
+ MaxElementSize: 100,
+}
+
+// For component suite, sync elements after writing
+suite.Writer.Write(ctx, writeReqs)
+suite.SyncElements() // Important: sync data to querier
+result, err := suite.Querier.Query(ctx, queryReq)
+```
+
+#### 2. Element Limit Exceeded Errors
+
+**Problem**: Write operations fail with "element limit exceeded" error.
+
+**Solution**:
+```go
+// Increase the element limit
+config := DefaultMockConfig()
+config.MaxElements = 100000 // Increase limit
+mockSIDX := NewMockSIDX(config)
+
+// Or clear elements periodically
+mockSIDX.Clear() // Clears all stored elements
+```
+
+#### 3. High Error Rates in Tests
+
+**Problem**: Operations fail frequently during testing.
+
+**Solution**:
+```go
+// Check error injection configuration
+config := DefaultMockConfig()
+config.ErrorRate = 0 // Disable error injection for stable tests
+mockSIDX := NewMockSIDX(config)
+
+// Or use SetErrorRate for dynamic control
+mockSIDX.SetErrorRate(0) // Disable errors
+// Run tests
+mockSIDX.SetErrorRate(10) // Enable 10% error rate for error testing
+```
+
+#### 4. Slow Test Performance
+
+**Problem**: Tests run slowly due to artificial delays.
+
+**Solution**:
+```go
+// Disable artificial delays for fast tests
+config := MockConfig{
+ WriteDelayMs: 0, // No write delay
+ QueryDelayMs: 0, // No query delay
+ FlushDelayMs: 0, // No flush delay
+ MergeDelayMs: 0, // No merge delay
+}
+mockSIDX := NewMockSIDX(config)
+
+// Or use dynamic delay configuration
+mockSIDX.SetWriteDelay(0)
+mockSIDX.SetQueryDelay(0)
+```
+
+#### 5. Memory Usage Issues
+
+**Problem**: High memory usage during testing.
+
+**Solution**:
+```go
+// Limit element count
+config := DefaultMockConfig()
+config.MaxElements = 1000 // Smaller limit
+
+// Clear elements periodically
+if elementCount > 500 {
+ mockSIDX.Clear()
+}
+
+// Monitor memory usage
+stats, _ := mockSIDX.Stats(ctx)
+fmt.Printf("Memory usage: %d bytes\n", stats.MemoryUsageBytes)
+```
+
+### Debug Tips
+
+#### Enable Verbose Logging
+
+```go
+frameworkConfig := DefaultFrameworkConfig()
+frameworkConfig.EnableVerboseLogging = true
+framework := NewIntegrationTestFramework(frameworkConfig)
+```
+
+#### Check Stats
+
+```go
+stats, err := mockSIDX.Stats(ctx)
+if err != nil {
+ log.Printf("Stats error: %v", err)
+} else {
+ log.Printf("Elements: %d, Memory: %d bytes, Queries: %d",
+ stats.ElementCount, stats.MemoryUsageBytes, stats.QueryCount)
+}
+```
+
+#### Verify Element Storage
+
+```go
+// Check what keys are stored (MockSIDX only)
+keys := mockSIDX.GetStorageKeys()
+log.Printf("Stored keys: %v", keys)
+
+// Check element count
+count := mockSIDX.GetElementCount()
+log.Printf("Element count: %d", count)
+```
+
+## Migration Guide
+
+### From Mock to Real Implementation
+
+When migrating from mock implementations to the real SIDX implementation:
+
+#### 1. Interface Compatibility
+
+The mock implementations follow the exact same interfaces as the real implementation:
+
+```go
+// This code works with both mock and real implementations
+var sidx SIDX
+if useMock {
+ sidx = NewMockSIDX(DefaultMockConfig())
+} else {
+ sidx = NewRealSIDX(realConfig) // Real implementation
+}
+
+// Same interface calls work for both
+err := sidx.Write(ctx, writeReqs)
+result, err := sidx.Query(ctx, queryReq)
+```
+
+#### 2. Configuration Migration
+
+Mock configuration translates to real configuration:
+
+```go
+// Mock configuration
+mockConfig := MockConfig{
+ WriteDelayMs: 5,
+ MaxElements: 10000,
+ EnableStrictValidation: true,
+}
+
+// Equivalent real configuration
+realConfig := RealConfig{
+ FlushThreshold: 10000, // Similar to MaxElements
+ EnableValidation: true, // Similar to EnableStrictValidation
+ // Real implementation has different performance characteristics
+}
+```
+
+#### 3. Performance Expectations
+
+Adjust performance expectations when migrating:
+
+| Aspect | Mock | Real Implementation |
+|--------|------|-------------------|
+| Write latency | <1ms | 1-10ms (with disk I/O) |
+| Query latency | <1ms | 5-50ms (with index lookup) |
+| Memory usage | High (all in memory) | Lower (disk-backed) |
+| Durability | None | Full durability |
+
+#### 4. Error Handling
+
+Real implementation may have different error patterns:
+
+```go
+// Mock errors are artificial
+if err != nil && isMockError(err) {
+ // Handle mock-specific errors
+}
+
+// Real implementation errors
+if err != nil {
+ // Handle disk I/O errors, corruption, etc.
+}
+```
+
+#### 5. Testing Strategy
+
+Maintain both mock and real implementation tests:
+
+```go
+func TestWithMock(t *testing.T) {
+ sidx := NewMockSIDX(DefaultMockConfig())
+ testSIDXBehavior(t, sidx)
+}
+
+func TestWithReal(t *testing.T) {
+ sidx := NewRealSIDX(testConfig)
+ testSIDXBehavior(t, sidx)
+}
+
+func testSIDXBehavior(t *testing.T, sidx SIDX) {
+ // Common test logic that works with both implementations
+}
+```
+
+## Limitations
+
+### Mock Implementation Limitations
+
+#### 1. Storage Limitations
+
+- **Memory-only**: No persistence across restarts
+- **No disk I/O**: Cannot test disk-related issues
+- **Linear search**: Query performance doesn't reflect real indexes
+- **No compression**: Data is stored uncompressed
+
+#### 2. Concurrency Limitations
+
+- **Simple locking**: Uses basic read-write locks (real implementation may have more sophisticated locking)
+- **No partition locking**: Real implementation may have finer-grained locking
+- **No write-ahead log**: No crash recovery simulation
+
+#### 3. Functional Limitations
+
+- **Simplified filtering**: Tag filtering is basic compared to real implementation
+- **No bloom filters**: Real implementation uses bloom filters for efficiency
+- **No background operations**: No background compaction or cleanup
+- **No resource limits**: Memory limits are artificial
+
+#### 4. Performance Limitations
+
+- **Not representative**: Performance characteristics don't match real implementation
+- **No I/O simulation**: Real I/O patterns are not simulated
+- **No network overhead**: Real distributed operations have network costs
+- **No garbage collection**: Memory management is simplified
+
+### Component Mock Limitations
+
+#### 1. Writer Limitations
+
+- **No batching optimization**: Real implementation may optimize batching
+- **No write-ahead log**: No durability guarantees
+- **Simplified sorting**: Sorting is basic in-memory sort
+
+#### 2. Querier Limitations
+
+- **Linear search**: No index structures
+- **No query optimization**: No query planning or optimization
+- **Basic filtering**: Tag filters are simplified
+
+#### 3. Flusher Limitations
+
+- **No actual persistence**: Flush operations are simulated
+- **No file format**: No real file writing or format handling
+- **No compression**: No data compression during flush
+
+#### 4. Merger Limitations
+
+- **Simulated consolidation**: Merge operations are simulated
+- **No real deduplication**: Element deduplication is simplified
+- **No background processing**: Merge operations are synchronous
+
+### Testing Limitations
+
+#### 1. Integration Testing
+
+- **No real I/O**: Cannot test disk failures, corruption, etc.
+- **No network issues**: Cannot test distributed system issues
+- **No resource contention**: Cannot test real resource constraints
+
+#### 2. Performance Testing
+
+- **Not representative**: Benchmark results don't predict real performance
+- **No I/O bottlenecks**: Cannot identify I/O-related performance issues
+- **Memory-bound**: Performance is limited by memory, not disk/network
+
+#### 3. Reliability Testing
+
+- **No crash recovery**: Cannot test crash recovery scenarios
+- **No data corruption**: Cannot test corruption detection and recovery
+- **No partial failures**: Cannot test partial system failures
+
+### Recommended Usage
+
+Given these limitations, the mock implementations are best used for:
+
+✅ **Development**: Early development when real implementation isn't ready
+✅ **Unit testing**: Testing component interactions and logic
+✅ **Integration testing**: Testing interface contracts and workflows
+✅ **Functional testing**: Testing business logic and data flow
+✅ **CI/CD pipelines**: Fast, reliable tests for continuous integration
+
+❌ **Performance tuning**: Real implementation needed for performance optimization
+❌ **Load testing**: Real implementation needed for realistic load testing
+❌ **Reliability testing**: Real implementation needed for failure scenarios
+❌ **Production simulation**: Real implementation needed for production-like testing
