ClickHouse/benchmark/bigquery

BigQuery has "DeWitt" clause that restricts from disclosing the benchmark results. Nevertheless, it does not prevent from doing the benchmarks.

It's very difficult to find, how to create a database. Databases are named "datasets". You need to press on ⋮ near project.

Create dataset test. Go to the query editor and paste the contents of create.sql. It will take two seconds to create a table.

Download Google Cloud CLI:

curl -O https://dl.google.com/dl/cloudsdk/channels/rapid/downloads/google-cloud-cli-392.0.0-linux-x86_64.tar.gz
tar -xf google-cloud-cli-392.0.0-linux-x86_64.tar.gz
./google-cloud-sdk/install.sh
source .bashrc
./google-cloud-sdk/bin/gcloud init

Load the data:

wget --continue 'https://datasets.clickhouse.com/hits_compatible/hits.csv.gz'
gzip -d hits.csv.gz

time bq load --source_format CSV --allow_quoted_newlines=1 test.hits hits.csv

Run the benchmark:

./run.sh 2>&1 | tee log.txt

cat log.txt |
  grep -P '^real|^Error' |
  sed -r -e 's/^Error.*$/null/; s/^real\s*([0-9.]+)m([0-9.]+)s$/\1 \2/' |
  awk '{ if ($2) { print $1 * 60 + $2 } else { print $1 } }' |
  awk '{ if ($1 == "null") { skip = 1 } else { if (i % 3 == 0) { printf "[" }; printf skip ? "null" : $1; if (i % 3 != 2) { printf "," } else { print "]," }; ++i; skip = 0; } }'
