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.

== 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.

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

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.
