Based on their implementation, RedisGraph uses the tuple-at-a-time model to process queries. However, some operators allow tuples to be batched before executing the operators' logic; for instance, the Conditional Traverse operator allows tuples to be batched with the predefined size.
Graph-related operators are mainly implemented with GraphBLAS:SuiteSparse, a linear algebra package for implementing graph algorithms based on GraphBLAS. For example, the Conditional Traverse operator contains a breadth-first search traversal algorithm. The breadth-first search traversal algorithm uses matrix-matrix multiplication from GraphBLAS:SuiteSparse.
