This is a side project I did for fun over the weekend. I've been using Mapd at work for a genomics project and wanted to apply what I've learned to some different data.
The data is extracted from the github archive using BigQuery and data/extract_prs.sql.
The backend is powered by containerized MapD databases on GCP n1-highcpu-8 instances. I'm using CPU only instances because the data size is relatively small and I'm on a budget :) so performance wise this won't do MapD justice. If you're interested in the type of performance MapD is capable of, Mark Litwintschik blog is a great resource.
The web app is built with angular and hosted on firebase. Visualizations are created using mapd-charting, mapd-crossfilter and mapd-connector.
MapD can work with or without a GPU. I'm using docker to simplify the
deployment process. There are two docker compose files, one for loading the data data/docker-compose.yml, and one for running the services docker-compose.yml. Both use a .env file to determine what MapD image to run. Currently I'm using my own personal images on docker hub, but you can build your own with https://github.com/shusson/docker-mapd or follow the official guide https://github.com/mapd/mapd-core/tree/master/docker.
I haven't automated getting the data from the github archive. The manual process is as follows:
- Use bigquery web console to create a new table from the results of data/extract_prs.sql.
- Export table into a GCP bucket (since the data is larger than 1GB you will have to use sharding)
- Download bucket contents and process with data/process_bq_data.sh to create a file
data/prs.csvwhich will be loaded by mapd.
Load the data (only required the first time)
