Creating an Index (1.1.6)
Function
This API is used to create indexes based on the specified information such as indexName and IndexType. Currently, composite indexes are supported.
- Composite indexes include global vertex indexes (GlobalCompositeVertexIndex) and global edge indexes (GlobalCompositeEdgeIndex). Composite indexes can be used to create indexes on labels and properties. Indexes can accelerate the query speed.
