Loading
move files to split directory
We didn't quite follow the getting started - so fix the location of the munged files
mkdir split
wikidata/data$ mv wiki* split
prepare log directory
sudo mkdir -p /var/log/wdqs/
sudo chown $(id -un) /var/log/wdqs/
mv service to TB harddisk
mv service s
mkdir service
mv s/* service
rm s
start blazegraph
nohup service/runBlazegraph.sh 2>&1 > blazegraph.log&
loadall.sh
This is the script i used in 2018:
#!/usr/bin/env bash
# load all data
START=1
END=100000
FORMAT=wikidump-%09d.ttl.gz
LOCATION=$(pwd)/data/split
BASE=$(dirname $0)
cd $BASE
while getopts s:e:d:h option
do
case "${option}"
in
s) START=${OPTARG};;
e) END=${OPTARG};;
d) LOCATION=${OPTARG};;
h)
echo "Usage: $0 [-s <start>] [-e <end>] [-d <directory>] [-h]"
exit 1
;;
esac
done
i=$START
while [ $i -le $END ]; do
printf -v f $FORMAT $i
if [ -f "$LOCATION/$f.good" ]
then
echo File $LOCATION/$f already imported
else
if [ ! -f "$LOCATION/$f" ]
then
echo File $LOCATION/$f not found, terminating
exit 0
else
ts=$(date -Iseconds)
echo Processing $f at $ts
./loadRestAPI.sh -n wdq -d "$LOCATION/$f"
fi
fi
let i++
done
load
nohup service/loadRestAPI.sh -n wdq -d `pwd`/data/split&
Logfile issue
The logfile size grows far too quickly with the default log settings.
For testing i reactivated my 128 GB RAM machine i used for the QLever tests last year.
Download munge files
cat data/split/getall
#!/bin/bash
# WF 2023-05-02
base=http://wikidata.dbis.rwth-aachen.de/downloads/split/
for i in {0001..1058}
do
file=wikidump-00000$i.ttl.gz
url=$base/wikidump-00000$i.ttl.gz
if [ ! -f $file ]
then
wget $url
else
echo "$file ✅"
fi
done
Run load for a single file
service/loadall.sh -s 1 -e 1

Check size of log file
The log file size grows at 26 MByte/s - that is far too much. E.g. this smaller 128 GB testmachine only has a 2TB SSD in the first place.
