f1-demo's Introduction

F1 demo

Real-time vehicle telematics analytics demo using OmniSci, debuted at NVIDIA GTC 2019 San Jose and later at OmniSci Converge 2019.

Dash app

This demo is built using only open-source components:

This repo is set up as a monorepo; see the data engineering and f1dash folders for the README's for StreamSets and Python/Dash code, respectively.

Blog Posts

The following blog posts were published to the OmniSci Blog to give an in-depth explanation of how everything works:

Data

We want to see what YOU would build with this dataset!

In addition to providing all of the code, OmniSci is providing the data for all laps in an S3 bucket. The table definitions are in the ddl folder; use OmniSci Core or OmniSci Cloud to load the data and to perform your queries, then use OmniSci Immerse or your favorite visualization tool to explore the data.

Please be respectful and make a copy to your own location rather than direct-linking against this bucket: s3://mapd-cloud/DataSets/vehicle_telematics_dataset_f12018/

f1-demo's Issues

Switch queries to use shared memory

Queries currently use slowest method to create pandas dataframes. Switching to select_ipc or select_ipc_gpu should allow for lowering the current query time of 7 seconds.

Use Avro instead of JSON

Per feedback from StreamSets, there might be a performance improvement if we switch to using Avro instead of JSON

Optimize querying in Dash app

In the Dash app, several queries are very similar in nature. It's likely possible that queries could be combined in a way such as to remove a few queries (even if each resulting query takes slightly longer).

Additionally, consider breaking out callback functions so that data queries separate from rendering.
