Task Details

Epic: #2977 (Phase 3: Modularity)
Priority: HIGH
Effort: 3 days
Dependencies: TASK-P3-005

Description

Extract index interfaces (~15 files) to separate module for index abstraction layer.

Steps

1. Create arcadedb-index-core module
2. Move index interfaces and base classes:
   • Index, IndexInternal
   • IndexCursor, IndexFactory
   • RangeIndex, TypeIndex
3. Update dependencies
4. Fix imports
5. Update tests
6. Verify compilation

Classes to Move (from engine)

• com.arcadedb.index.Index* (interfaces)
• com.arcadedb.index.IndexFactory
• ~15 index core files
