MuSEA Graph Format: Mini-Batch Sorting for Scalability

Bubble's core innovation, MuSEA, re-architects graph storage using a multi-segment edge array. It leverages mini-batch sorting that fits within L2 cache, enabling parallel updates across many partitions without LLC contention. This design ensures high ingestion throughput by utilizing private CPU caches and performing larger merges periodically.

Key features include adaptive indexes for efficient vertex-centric queries, balancing insertion efficiency with memory usage, and a merging policy that controls write amplification. This approach significantly reduces the impact of random DRAM accesses and improves cache affinity.

High-Parallel Batch Ingestion Policy

To overcome workload imbalance and dispatching overhead, Bubble employs a novel parallel ingestion policy. This includes a scalable multi-core dispatcher with lock-free structures, allowing multiple threads to append updates to the same partition simultaneously without synchronization. A work-stealing mechanism enables idle worker threads to assist busy partitions, mitigating skewness-induced load imbalance during sorting newly appended edges.

This design significantly improves CPU utilization and dispatching throughput, addressing critical bottlenecks observed in state-of-the-art systems when scaling to dozens of threads.

Optimizations for Graph Analytics

Bubble enhances graph analytics performance through both a general vertex-centric API and several query-optimized APIs tailored for common graph access patterns. Optimizations include horizontal scanning for algorithms requiring full edge scans, multi-head iterators for ordered neighbor retrieval (e.g., Triangle Counting), and an in-analytics cache to store query results and precomputed vertex degrees, reducing repeated binary searches.

These strategies convert query requests into sequential scans where possible and mitigate overhead caused by discontinuous neighbor storage, ensuring efficient performance across various graph algorithms like BFS, PageRank, and CC.

Case Study: Real-time Fraud Detection with Bubble

A leading financial institution struggled with its legacy graph system to detect fraud in real-time due to slow ingestion of new transaction data and high latency in graph analytics. Adopting Bubble's MuSEA format enabled them to ingest millions of new transactions per second with near-linear scalability. The optimized analytics allowed their fraud detection algorithms to run up to 3.29x faster, reducing false positives by 15% and saving millions annually. This transformation was powered by Bubble's ability to minimize cache contention and balance workloads dynamically, ensuring their system remained responsive even during peak transaction volumes.
