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
