DynATOS Queries

Scripts used for generating query workloads for evaluation of DynATOS.

Referenced from "Dynamic Scheduling of Approximate Telemetry Queries" (NSDI '22).

Contents

• gen_query_workload.py: A python script for generating dynamic query workload specifications. Each specification is a (timed) sequence of "base" queries and a required number of "followup" queries for each base query.

• query_workload_driver.c: A C program for running a dynamic query workload specification. Interfaces with the switch module (not included here) to execute base and followup queries. Writes query results and metadata from the switch module.

• example_workloads/: A directory with example workloads generated by gen_query_workload.py.

• example_metadata/: A directory with example metadata as read from the switch module and output by query_workload_driver.c.

Notes

Source code for our switch module, which contains the DynATOS scheduler is not yet publicly available. Please contact Chris (cmisa@cs.uoregon.edu) for more details.
