Multi-Stage Tree Graph (MSTG) is a hierarchical vector index developed by MyScale that overcomes limitations of traditional IVF (Inverted File Index) through a hierarchical design.
MSTG creates multiple layers unlike IVF which has a single layer of cluster vectors. This hierarchical approach enables:
The multi-stage architecture allows for:
The tree-based structure enables faster traversal compared to flat IVF indexes, especially for large-scale datasets.
Provides improved performance over traditional IVF while maintaining computational efficiency through intelligent hierarchical organization.
Available as part of MyScale vector database.
