A Runtime System for Interruptible Query Processing: When Incremental Computing Meets Fine-Grained Parallelism - Artifact

The goal of PitStop is to use lazy evaluation to improve both throughput and operation latency for data processing systems. PitStop allows for queries and updates to be temporarily halted mid-traversal and continued at a later time. Though it may seem counter intuitive, this pausing allows for a fine-grained parallelism that helps to balance workload and alleviate workload fluctuation. This design also allows for further query optimization through the use of techniques such as batching and fusion.
