arXiv:2606.18379v1 Announce Type: cross Abstract: Graph-based retrieval at billion-node scale requires jointly solving three tightly coupled problems -- graph construction, representation learning, and real-time serving -- yet existing work addresses each in isolation. We present RankGraph-2, a framework deployed at Meta that co-designs all three lifecycle stages for similarity-based retrieval (U2U2I and U2I2I), where each stage's requirements shape the others. Serving requires a co-learned cluster index to avoid expensive online KNN -- this pushes index co-training into the training objective
The continuous growth of data and demand for personalized recommendations necessitates more efficient and scalable graph learning solutions.
This development from Meta signifies a practical breakthrough in handling real-time, large-scale graph-based recommendations, impacting how major platforms deliver personalized experiences.
The co-design approach integrating graph construction, representation learning, and real-time serving simplifies and optimizes the deployment of billion-node recommenders.
