Bikeshare Example Database

Examples used in the TiDB manual use System Data from Capital Bikeshare, released under the Capital Bikeshare Data License Agreement.

Download all data files

The system data is available for download in .zip files organized per year. Downloading and extracting all files requires approximately 3GB of disk space. To download all files for years 2010-2017 using a bash script:

mkdir -p bikeshare-data && cd bikeshare-data

for YEAR in 2010 2011 2012 2013 2014 2015 2016 2017; do
 wget https://s3.amazonaws.com/capitalbikeshare-data/${YEAR}-capitalbikeshare-tripdata.zip
 unzip ${YEAR}-capitalbikeshare-tripdata.zip
done;

Load data into TiDB

The system data can be imported into TiDB using the following schema:

CREATE DATABASE bikeshare;
USE bikeshare;

CREATE TABLE trips (
 trip_id bigint NOT NULL PRIMARY KEY AUTO_INCREMENT,
 duration integer not null,
 start_date datetime,
 end_date datetime,
 start_station_number integer,
 start_station varchar(255),
 end_station_number integer,
 end_station varchar(255),
 bike_number varchar(255),
 member_type varchar(255)
);

You can import files individually using the example LOAD DATA command here, or import all files using the bash loop below:

LOAD DATA LOCAL INFILE '2017Q1-capitalbikeshare-tripdata.csv' INTO TABLE trips
  FIELDS TERMINATED BY ',' ENCLOSED BY '"'
  LINES TERMINATED BY '\r\n'
  IGNORE 1 LINES
(duration, start_date, end_date, start_station_number, start_station, 
end_station_number, end_station, bike_number, member_type);

Import all files

To import all *.csv files into TiDB in a bash loop:

for FILE in `ls *.csv`; do
 echo "== $FILE =="
 mysql bikeshare -e "LOAD DATA LOCAL INFILE '${FILE}' INTO TABLE trips FIELDS TERMINATED BY ',' ENCLOSED BY '\"' LINES TERMINATED BY '\r\n' IGNORE 1 LINES (duration, start_date, end_date, start_station_number, start_station, end_station_number, end_station, bike_number, member_type);"
done;
