# Benchmarks
Currently this repository hosts two kinds of benchmarks:
1. The older "milli benchmarks", that use [criterion](https://github.com/bheisler/criterion.rs) and live in the "benchmarks" directory.
2. The newer "bench" that are workload-based and so split between the [`workloads`](./workloads/) directory and the [`xtask::bench`](./xtask/src/bench/) module.
This document describes the newer "bench" benchmarks. For more details on the "milli benchmarks", see [benchmarks/README.md](./benchmarks/README.md).
## Design philosophy for the benchmarks
The newer "bench" benchmarks are **integration** benchmarks, in the sense that they spawn an actual Meilisearch server and measure its performance end-to-end, including HTTP request overhead.
Since this is prone to fluctuating, the benchmarks regain a bit of precision by measuring the runtime of the individual spans using the [logging machinery](./CONTRIBUTING.md#logging) of Meilisearch.
A span roughly translates to a function call. The benchmark runner collects all the spans by name using the [logs route](https://github.com/orgs/meilisearch/discussions/721) and sums their runtime. The processed results are then sent to the [benchmark dashboard](https://bench.meilisearch.dev), which is in charge of storing and presenting the data.
## Running the benchmarks
Benchmarks can run locally or in CI.
### Locally
#### With a local benchmark dashboard
The benchmarks dashboard lives in its [own repository](https://github.com/meilisearch/benchboard). We provide binaries for Ubuntu/Debian, but you can build from source for other platforms (MacOS should work as it was developed under that platform).
Run the `benchboard` binary to create a fresh database of results. By default it will serve the results and the API to gather results on `http://localhost:9001`.
From the Meilisearch repository, you can then run benchmarks with:
```sh
cargo xtask bench -- workloads/my_workload_1.json ..
```
This command will build and run Meilisearch locally on port 7700, so make sure that this port is available.
To run benchmarks on a different commit, just use the usual git command to get back to the desired commit.
#### Without a local benchmark dashboard
To work with the raw results, you can also skip using a local benchmark dashboard.
Run:
```sh
cargo xtask bench --no-dashboard -- workloads/my_workload_1.json workloads/my_workload_2.json ..
```
For processing the results, look at [Looking at benchmark results/Without dashboard](#without-dashboard).
### In CI
We have dedicated runners to run workloads on CI. Currently, there are three ways of running the CI:
1. Automatically, on every push to `main`.
2. Manually, by clicking the [`Run workflow`](https://github.com/meilisearch/meilisearch/actions/workflows/bench-manual.yml) button and specifying the target reference (tag, commit or branch) as well as one or multiple workloads to run. The workloads must exist in the Meilisearch repository (conventionally, in the [`workloads`](./workloads/) directory) on the target reference. Globbing (e.g., `workloads/*.json`) works.
3. Manually on a PR, by posting a comment containing a `/bench` command, followed by one or multiple workloads to run. Globbing works. The workloads must exist in the Meilisearch repository in the branch of the PR.
```
/bench workloads/movies*.json /hackernews_1M.json
```
## Looking at benchmark results
### On the dashboard
Results are available on the global dashboard used by CI at <https://bench.meilisearch.dev> or on your [local dashboard](#with-a-local-benchmark-dashboard).
The dashboard homepage presents three sections:
1. The latest invocations (a call to `cargo xtask bench`, either local or by CI) with their reason (generally set to some helpful link in CI) and their status.
2. The latest workloads ran on `main`.
3. The latest workloads ran on other references.
By default, the workload shows the total runtime delta with the latest applicable commit on `main`. The latest applicable commit is the latest commit for workload invocations that do not originate on `main`, and the latest previous commit for workload invocations that originate on `main`.
You can explicitly request a detailed comparison by span with the `main` branch, the branch or origin, or any previous commit, by clicking the links at the bottom of the workload invocation.
In the detailed comparison view, the spans are sorted by improvements, regressions, stable (no statistically significant change) and unstable (the span runtime is comparable to its standard deviation).
You can click on the name of any span to get a box plot comparing the target commit with multiple commits of the selected branch.
### Without dashboard
After the workloads are done running, the reports will live in the Meilisearch repository, in the `bench/reports` directory (by default).
You can then convert these reports into other formats.
- To [Firefox profiler](https://profiler.firefox.com) format. Run:
```sh
cd bench/reports
cargo run --release --bin trace-to-firefox -- my_workload_1-0-trace.json
```
You can then upload the resulting `firefox-my_workload_1-0-trace.json` file to the online profiler.
## Designing benchmark workloads
Benchmark workloads conventionally live in the `workloads` directory of the Meilisearch repository.
They are JSON files with the following structure (comments are not actually supported, to make your own, remove them or copy some existing workload file):
```jsonc
{
// Name of the workload. Must be unique to the workload, as it will be used to group results on the dashboard.
"name": "hackernews.ndjson_1M,no-threads",
// Number of consecutive runs of the commands that should be performed.
// Each run uses a fresh instance of Meilisearch and a fresh database.
// Each run produces its own report file.
"run_count": 3,
// List of arguments to add to the Meilisearch command line.
"extra_cli_args": ["--max-indexing-threads=1"],
// List of named assets that can be used in the commands.
"assets": {
// name of the asset.
// Must be unique at the workload level.
// For better results, the same asset (same sha256) should have the same name accross workloads.
// Having multiple assets with the same name and distinct hashes is supported accross workloads,
// but will lead to superfluous downloads.
//
// Assets are stored in the `bench/assets/` directory by default.
"hackernews-100_000.ndjson": {
// If the assets exists in the local filesystem (Meilisearch repository or for your local workloads)
// Its file path can be specified here.
// `null` if the asset should be downloaded from a remote location.
"local_location": null,
// URL of the remote location where the asset can be downloaded.
// Use the `--assets-key` of the runner to pass an API key in the `Authorization: Bearer` header of the download requests.
// `null` if the asset should be imported from a local location.
// if both local and remote locations are specified, then the local one is tried first, then the remote one
// if the file is locally missing or its hash differs.
"remote_location": "https://milli-benchmarks.fra1.digitaloceanspaces.com/bench/datasets/hackernews/hackernews-100_000.ndjson",
// SHA256 of the asset.
// Optional, the `sha256` of the asset will be displayed during a run of the workload if it is missing.
// If present, the hash of the asset in the `bench/assets/` directory will be compared against this hash before
// running the workload. If the hashes differ, the asset will be downloaded anew.
"sha256": "60ecd23485d560edbd90d9ca31f0e6dba1455422f2a44e402600fbb5f7f1b213",

### Adding new assets
Assets reside in our DigitalOcean S3 space. Assuming you have team access to the DigitalOcean S3 space:
1. go to <https://cloud.digitalocean.com/spaces/milli-benchmarks?i=d1c552&path=bench%2Fdatasets%2F>
2. upload your dataset:
1. if your dataset is a single file, upload that single file using the "upload" button,
2. otherwise, create a folder using the "create folder" button, then inside that folder upload your individual files.
## Upgrading `https://bench.meilisearch.dev`
The URL of the server is in our password manager (look for "benchboard").
1. Make the needed modifications on the [benchboard repository](https://github.com/meilisearch/benchboard) and merge them to main.
2. Publish a new release to produce the Ubuntu/Debian binary.
3. Download the binary locally, send it to the server:
```
scp -6 ~/Downloads/benchboard root@\[<ipv6-address>\]:/bench/new-benchboard
```
Note that the ipv6 must be between escaped square brackets for SCP.
4. SSH to the server:
```
ssh root@<ipv6-address>
```
Note the ipv6 must **NOT** be between escaped square brackets for SSH 🥲
5. On the server, set the correct permissions for the new binary:
```
chown bench:bench /bench/new-benchboard
chmod 700 /bench/new-benchboard
```
6. On the server, move the new binary to the location of the running binary (if unsure, start by making a backup of the running binary):
```
mv /bench/{new-,}benchboard
```
7. Restart the benchboard service.
```
systemctl restart benchboard
```
8. Check that the service runs correctly.
```
systemctl status benchboard
```
9. Check the availability of the service by going to <https://bench.meilisearch.dev> on your browser.

### Logging
Meilisearch uses [`tracing`](https://lib.rs/crates/tracing) for logging purposes. Tracing logs are structured and can be displayed as JSON to the end user, so prefer passing arguments as fields rather than interpolating them in the message.
Refer to the [documentation](https://docs.rs/tracing/0.1.40/tracing/index.html#using-the-macros) for the syntax of the spans and events.
Logging spans are used for 3 distinct purposes:
1. Regular logging
2. Profiling
3. Benchmarking
As a result, the spans should follow some rules:
- They should not be put on functions that are called too often. That is because opening and closing a span causes some overhead. For regular logging, avoid putting spans on functions that are taking less than a few hundred nanoseconds. For profiling or benchmarking, avoid putting spans on functions that are taking less than a few microseconds.
- For profiling and benchmarking, use the `TRACE` level.
- For profiling and benchmarking, use the following `target` prefixes:
- `indexing::` for spans meant when profiling the indexing operations.
- `search::` for spans meant when profiling the search operations.
### Benchmarking

//! This file implements a queue of searches to process and the ability to control how many searches can be run in parallel.
//! We need this because we don't want to process more search requests than we have cores.
//! That slows down everything and consumes RAM for no reason.
//! The steps to do a search are to get the `SearchQueue` data structure and try to get a search permit.
//! This can fail if the queue is full, and we need to drop your search request to register a new one.
//!
//! ### How to do a search request
//!
//! In order to do a search request you should try to get a search permit.
//! Retrieve the `SearchQueue` structure from actix-web (`search_queue: Data<SearchQueue>`)
//! and right before processing the search, calls the `SearchQueue::try_get_search_permit` method: `search_queue.try_get_search_permit().await?;`
//!
//! What is going to happen at this point is that you're going to send a oneshot::Sender over an async mpsc channel.
//! Then, the queue/scheduler is going to either:
//! - Drop your oneshot channel => that means there are too many searches going on, and yours won't be executed.
//! You should exit and free all the RAM you use ASAP.
//! - Sends you a Permit => that will unlock the method, and you will be able to process your search.
//! And should drop the Permit only once you have freed all the RAM consumed by the method.
