SRBench

This repository contains the CSV data of SRBench [1]

Download

Check out the release section to download the latest dataset version. Two different serializations are available:

• CSV: the folder structure resembles the original data format.

charley/
└── extracted/
    ├── sensor_X/
    │   └── AirTemperature/
    │       └──file.csv
    ├── sensor_Y/
    └── sensor_Z/

• JSON-PG [2]: the data is organized in JSON files. Each file is named with a UNIX timestamp and contains the JSON-PG serialization of the events that occurred at the specified time instant.

charley/
└── pg-json/
    ├── 1091923500.json
    └── 1091923800.json

Build

To generate JSON-PG representation:

• Build docker image:

docker build -t json-pg .

• Run the docker image mounting the input and output volumes as follows:

docker run \
    -v ${PWD}/input/charley:/data/input \
    -v ${PWD}/output/charley:/data/output \
    json-pg

• The output folder contains the PG-JSON representation of the data.
