-- **Priority 2**: UPDATE Performance (Batch)
-  - **Current**: 37.94x speedup with BeginBatchUpdate
-  - **Target**: Extend to SQL batch API
-  - **Approach**: Implicit batch detection, auto-deferred indexes
-  - **Est. Impact**: 5-10x speedup
+- **Priority 2**: B-tree Indexes Implementation
+  - **Current**: Hash indexes only (O(1) point lookups)
+  - **Target**: Add B-tree for range queries and ordering
+  - **Approach**: Implement B-tree index structure, integrate with query planner
+  - **Est. Impact**: Enable ORDER BY, BETWEEN, range scans
 
 ### Q2-Q3 2026 - Advanced Optimizations
 
-- B-tree Index Implementation: Ordered iteration, range queries
 - Query Planner/Optimizer: Cost-based plans, join optimization
 - Advanced Caching: Multi-level caching, adaptive prefetching
 - Parallel Scans: SIMD + parallelization for large datasets
