Only stores non-zero values in the payload + - Bitmap overhead is minimal compared to savings + - Original size reduced by 16.88% to 96.75% depending on sparsity + +2. **Compression Efficiency**: Layout2's smaller original size leads to better compression + - Compressed size reduced by 6.39% to 56.85% + - Best results with no additional compression layer (56.85%) + - Works well across all compression types (ZSTD, None) + +3. **Scalability**: Benefits increase with more features and higher sparsity + - 850 features with 95% defaults: 91.79% original size reduction + - 100 features with 100% defaults: 96.75% original size reduction + +4. **Data Type Agnostic**: Works well across different data types + - FP32: 6-28% improvement + - FP16: 28.54% improvement (tested) + +### ⚠️ Layout2 Trade-offs + +1. **Bitmap Overhead**: With 0% defaults (all non-zero values) + - Small overhead of ~3.5% due to bitmap metadata + - This is an edge case rarely seen in production feature stores + - In practice, feature vectors almost always have some sparse data + +2. **Complexity**: Slightly more complex serialization/deserialization + - Requires bitmap handling logic + - Worth the trade-off for significant space savings + +## Production Implications + +### When to Use Layout2 + +✅ **Always use Layout2** for: +- Sparse feature vectors (common in ML feature stores) +- Any scenario with >5% default/zero values +- Large feature sets (500+ features) +- Storage-constrained environments + +### When Layout1 Might Be Acceptable + +- Extremely small feature sets (<50 features) with no defaults +- Dense feature vectors with absolutely no zero values (rare) +- Bitmap overhead of 3.5% is acceptable + +## Bitmap Optimization Tests + +Layout2's bitmap implementation correctly handles: + +| Pattern | Non-Zero Count | Original Size | Verification | +|---------|---------------|---------------|--------------| +| All zeros except first | 1/100 (1.0%) | 17 bytes | ✅ PASS | +| All zeros except last | 1/100 (1.0%) | 17 bytes | ✅ PASS | +| Alternating pattern | 6/100 (6.0%) | 37 bytes | ✅ PASS | +| Clustered non-zeros | 5/200 (2.5%) | 45 bytes | ✅ PASS | + +**Formula**: `Original Size = Bitmap Size + (Non-Zero Count × Value Size)` + +## Conclusion + +**Layout2 should be the default choice** for the online feature store.

**Consistent benefits** with any amount of default values +- ✅ **Negligible overhead** (3.5%) only in unrealistic edge case (0% defaults) + +### Recommendation + +**Use Layout2 as the default layout

-## Key Findings - -### ✅ Layout2 Advantages - -1. **Sparse Data Optimization**: Layout2 uses bitmap-based storage to skip default/zero values - - Only stores non-zero values in the payload - - Bitmap overhead is minimal compared to savings - - Original size reduced by 16.88% to 96.75% depending on sparsity - -2. **Compression Efficiency**: Layout2's smaller original size leads to better compression - - Compressed size reduced by 6.39% to 56.85% - - Best results with no additional compression layer (56.85%) - - Works well across all compression types (ZSTD, None) - -3. **Scalability**: Benefits increase with more features and higher sparsity - - 850 features with 95% defaults: 91.79% original size reduction - - 100 features with 100% defaults: 96.75% original size reduction - -4. **Data Type Agnostic**: Works well across different data types - - FP32: 6-28% improvement - - FP16: 28.54% improvement (tested) - -### ⚠️ Layout2 Trade-offs - -1. **Bitmap Overhead**: With 0% defaults (all non-zero values) - - Small overhead of ~3.5% due to bitmap metadata - - This is an edge case rarely seen in production feature stores - - In practice, feature vectors almost always have some sparse data - -2. **Complexity**: Slightly more complex serialization/deserialization - - Requires bitmap handling logic - - Worth the trade-off for significant space savings - -## Production Implications - -### When to Use Layout2 - -✅ **Always use Layout2** for: -- Sparse feature vectors (common in ML feature stores) -- Any scenario with >5% default/zero values -- Large feature sets (500+ features) -- Storage-constrained environments - -### When Layout1 Might Be Acceptable - -- Extremely small feature sets (<50 features) with no defaults -- Dense feature vectors with absolutely no zero values (rare) -- Bitmap overhead of 3.5% is acceptable - -## Bitmap Optimization Tests - -Layout2's bitmap implementation correctly handles: - -| Pattern | Non-Zero Count | Original Size | Verification | -|---------|---------------|---------------|--------------| -| All zeros except first | 1/100 (1.0%) | 17 bytes | ✅ PASS | -| All zeros except last | 1/100 (1.0%) | 17 bytes | ✅ PASS | -| Alternating pattern | 6/100 (6.0%) | 37 bytes | ✅ PASS | -| Clustered non-zeros | 5/200 (2.5%) | 45 bytes | ✅ PASS | - -**Formula**: `Original Size = Bitmap Size + (Non-Zero Count × Value Size)` - -## Conclusion - -**Layout2 should be the default choice** for the online feature store. The test results conclusively prove that Layout2 provides: - -- ✅ **6-57% compressed size reduction** across real-world scenarios -- ✅ **17-97% original size reduction** depending on sparsity -- ✅ **Consistent benefits** with any amount of default values -- ✅ **Negligible overhead** (3.5%) only in unrealistic edge case (0% defaults) - -### Recommendation - -**Use Layout2 as the default layout version** for all new deployments and migrate existing Layout1 data during normal operations. - -## Test Implementation - -The comprehensive test suite is located at: -`online-feature-store/internal/data/blocks/layout_comparison_test.go` -

present is the 72nd bit (10th byte bit 0). Bool scalar (derived_bool) is layout-1 only and excluded from layout-2 comparison. -- With 0% defaults, Layout2 has small bitmap overhead; with 50%/80%/100% defaults, Layout2 reduces size. - -## Test
