Modern Techniques for Querying Graph-Structured Relations: …
WebWhen generating hybrid plans, our dynamic programming optimizer for one-time queries combines intersection-cost with the cost of binary joins. We demonstrate the effectiveness of our plans, adaptive technique, and partial intersection sharing optimization through extensive experiments. Our optimizers are integrated into GraphflowDB. WebThis repository contains 2 versions of GraphflowDB. GF-RV [ link ]: The baseline version that implements vanilla row-based storage and a volcano-based processor. GF-CL [ link ]: Version of GraphflowDB that implements our novel column-oriented storage and the List-based Processor. Both projects follow common instructions for building and ... east coast wildfire smoke

WebJan 20, 2024 · The linear plan is from our previous GraphflowDB system. Here you are seeing an operator called Extend, which joins node records with their Transfer relationships to read the system-level IDs of the neighbors of those node records. Following the Extend is another Join operator to join the accID properties of those neighbors (specifically c ... east coast windsor funeral home
