Run the benchmarks
On our private server
The Meili team has self-hosted his own GitHub runner to run benchmarks on our dedicated bare metal server.
To trigger the benchmark workflow:
- Go to the
Actions
tab of this repository. - Select the
Benchmarks
workflow on the left. - Click on
Run workflow
in the blue banner. - Select the branch on which you want to run the benchmarks and select the dataset you want (default:
songs
). - Finally, click on
Run workflow
.
This GitHub workflow will run the benchmarks and push the critcmp
report to a DigitalOcean Space (= S3).
The name of the uploaded file is displayed in the workflow.
💡 To compare the just-uploaded benchmark with another one, check out the next section.
On your machine
To run all the benchmarks (~5h):
cargo bench
To run only the search_songs
(~1h), search_wiki
(~3h), search_geo
(~20m) or indexing
(~2h) benchmark:
cargo bench --bench <dataset name>
By default, the benchmarks will be downloaded and uncompressed automatically in the target directory.
If you don't want to download the datasets every time you update something on the code, you can specify a custom directory with the environment variable MILLI_BENCH_DATASETS_PATH
:
mkdir ~/datasets
MILLI_BENCH_DATASETS_PATH=~/datasets cargo bench --bench search_songs # the four datasets are downloaded
touch build.rs
MILLI_BENCH_DATASETS_PATH=~/datasets cargo bench --bench songs # the code is compiled again but the datasets are not downloaded
Comparison between benchmarks
The benchmark reports we push are generated with critcmp
. Thus, we use critcmp
to show the result of a benchmark, or compare results between multiple benchmarks.
We provide a script to download and display the comparison report.
Requirements:
grep
curl
critcmp
List the available file in the DO Space:
./benchmarks/script/list.sh
songs_main_09a4321.json
songs_geosearch_24ec456.json
search_songs_main_cb45a10b.json
Run the comparison script:
# we get the result of ONE benchmark, this give you an idea of how much time an operation took
./benchmarks/scripts/compare.sh son songs_geosearch_24ec456.json
# we compare two benchmarks
./benchmarks/scripts/compare.sh songs_main_09a4321.json songs_geosearch_24ec456.json
# we compare three benchmarks
./benchmarks/scripts/compare.sh songs_main_09a4321.json songs_geosearch_24ec456.json search_songs_main_cb45a10b.json
Datasets
The benchmarks uses the following datasets:
smol-songs
smol-wiki
movies
smol-all-countries
Songs
smol-songs
is a subset of the songs.csv
dataset.
It was generated with this command:
xsv sample --seed 42 1000000 songs.csv -o smol-songs.csv
Download the generated smol-songs
dataset.
Wiki
smol-wiki
is a subset of the wikipedia-articles.csv
dataset.
It was generated with the following command:
xsv sample --seed 42 500000 wiki-articles.csv -o smol-wiki-articles.csv
Download the smol-wiki
dataset.
Movies
movies
is a really small dataset we uses as our example in the getting started
All Countries
smol-all-countries
is a subset of the all-countries.csv
dataset
It has been converted to jsonlines and then edited so it matches our format for the _geo
field.
It was generated with the following command:
bat all-countries.csv.gz | gunzip | xsv sample --seed 42 1000000 | csv2json-lite | sd '"latitude":"(.*?)","longitude":"(.*?)"' '"_geo": { "lat": $1, "lng": $2 }' | sd '\[|\]|,$' '' | gzip > smol-all-countries.jsonl.gz
