Replace the HashMap caches by BTreeMaps

5125: Change the default max memory usage to 5% of the total memory r=ManyTheFish a=Kerollmops

After thorough testing, we found that giving 5% of the total available memory to allocate resident memory (caches and channels) is the best approach.

The main reason is that the new indexer is highly memory-map oriented, with LMDB, and reads the database while performing the indexation. So, by allowing the maximum amount of memory available to LMDB and the OS, it will perform the key-value store reads and all other indexation operations faster by keeping more pages hot in the cache. In #5124, we also sorted the entries to merge to improve the read speed of LMDB.

This is common in database management systems: Reading stuff on the disk is much faster when done in lexicographic order (the default sorted order of key values). The entries have a great chance of already being in the OS memory cache, as they were loaded in a previous read, and reading stuff on the disk is very slow compared to reading memory.

+
+### Reminders when modifying the Setting API
+
+<!--- Special steps to remind when adding a new index setting -->
+
+- [ ] Ensure the new setting route is at least tested by the [`test_setting_routes` macro](https://github.com/meilisearch/meilisearch/blob/5204c0b60b384cbc79621b6b2176fca086069e8e/meilisearch/tests/settings/get_settings.rs#L276)
+- [ ] Ensure Analytics are fully implemented
+  - [ ] `/settings/my-new-setting` configurated in the [`make_setting_routes` macro](https://github.com/meilisearch/meilisearch/blob/5204c0b60b384cbc79621b6b2176fca086069e8e/meilisearch/src/routes/indexes/settings.rs#L141-L165)
+  - [ ] global `/settings` route configurated in the [`update_all` function](https://github.com/meilisearch/meilisearch/blob/5204c0b60b384cbc79621b6b2176fca086069e8e/meilisearch/src/routes/indexes/settings.rs#L655-L751)
+- [ ] Ensure the dump serializing is consistent with the `/settings` route serializing, e.g., enums case can be different (`camelCase` in route and `PascalCase` in the dump)
+
+#### Special cases when adding a setting for an experimental feature
+
+- [ ] ⚠️ API stability: The setting does not appear on the main settings route when the feature has never been enabled (e.g. mark it `Unset` when returned from the index in this situation. See [an example](https://github.com/meilisearch/meilisearch/blob/7a89abd2a025606a42f8b219e539117eb2eb029f/meilisearch-types/src/settings.rs#L608))
+- [ ] The setting cannot be set when the feature is disabled, either by the main settings route or the subroute (see [`validate_settings` function](https://github.com/meilisearch/meilisearch/blob/7a89abd2a025606a42f8b219e539117eb2eb029f/meilisearch/src/routes/indexes/settings.rs#L811))
+- [ ] If possible, the setting is reset when the feature is disabled (hard if it requires reindexing)

+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"],
+  // An expression that can be parsed as a comma-separated list of targets and levels
+  // as described in [tracing_subscriber's documentation](https://docs.rs/tracing-subscriber/latest/tracing_subscriber/filter/targets/struct.Targets.html#examples).
+  // The expression is used to filter the spans that are measured for profiling purposes.
+  // Optional, defaults to "indexing::=trace" (for indexing workloads), common other values is
+  // "search::=trace"
+  "target": "indexing::=trace",
+  // 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)

+
+### 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.

 Depending on the developed feature, you might need to provide a prototyped version of Meilisearch to make it easier to test by the users.
 
-The prototype name must follow this convention: `prototype-X-Y` where
-- `X` is the feature name formatted in `kebab-case`. It should not end with a single number.
-- `Y` is the version of the prototype, starting from `0`.
-
-✅ Example: `prototype-auto-resize-0`. </br>
-❌ Bad example: `auto-resize-0`: lacks the `prototype` prefix. </br>
-❌ Bad example: `prototype-auto-resize`: lacks the version suffix. </br>
-❌ Bad example: `prototype-auto-resize-0-0`: feature name ends with a single number.
-
-Steps to create a prototype:
-
-1. In your terminal, go to the last commit of your branch (the one you want to provide as a prototype).
-2. Create a tag following the convention: `git tag prototype-X-Y`
-3. Run Meilisearch and check that its launch summary features a line: `Prototype: prototype-X-Y` (you may need to switch branches and back after tagging for this to work).
-3. Push the tag: `git push origin prototype-X-Y`
-4. Check the [Docker CI](https://github.com/meilisearch/meilisearch/actions/workflows/publish-docker-images.yml) is now running.
-
-🐳 Once the CI has finished to run (~1h30), a Docker image named `prototype-X-Y` will be available on [DockerHub](https://hub.docker.com/repository/docker/getmeili/meilisearch/general). People can use it with the following command: `docker run -p 7700:7700 -v $(pwd)/meili_data:/meili_data getmeili/meilisearch:prototype-X-Y`. <br>
-More information about [how to run Meilisearch with Docker](https://docs.meilisearch.com/learn/cookbooks/docker.html#download-meilisearch-with-docker).
-
-⚙️ However, no binaries will be created. If the users do not use Docker, they can go to the `prototype-X-Y` tag in the Meilisearch repository and compile from the source code.
-
-⚠️ When sharing a prototype with users, remind them to not use it in production. Prototypes are solely for test purposes.
+This happens in two steps:
+- [Release the prototype](https://github.com/meilisearch/engine-team/blob/main/resources/prototypes.md#how-to-publish-a-prototype)
+- [Communicate about it](https://github.com/meilisearch/engine-team/blob/main/resources/prototypes.md#communication)

+# Profiling Meilisearch
+
+Search engine technologies are complex pieces of software that require thorough profiling tools. We chose to use [Puffin](https://github.com/EmbarkStudios/puffin), which the Rust gaming industry uses extensively. You can export and import the profiling reports using the top bar's _File_ menu options [in Puffin Viewer](https://github.com/embarkstudios/puffin#ui).
+
+![An example profiling with Puffin viewer](assets/profiling-example.png)
+
+## Profiling the Indexing Process
+
+When you enable [the `exportPuffinReports` experimental feature](https://www.meilisearch.com/docs/learn/experimental/overview) of Meilisearch, Puffin reports with the `.puffin` extension will be automatically exported to disk. When this option is enabled, the engine will automatically create a "frame" whenever it executes the `IndexScheduler::tick` method.
+
+[Puffin Viewer](https://github.com/EmbarkStudios/puffin/tree/main/puffin_viewer) is used to analyze the reports. Those reports show areas where Meilisearch spent time during indexing.
+
+Another piece of advice on the Puffin viewer UI interface is to consider the _Merge children with same ID_ option. It can hide the exact actual timings at which events were sent. Please turn it off when you see strange gaps on the Flamegraph. It can help.
+
+## Profiling the Search Process
+
+We still need to take the time to profile the search side of the engine with Puffin. It would require time to profile the filtering phase, query parsing, creation, and execution. We could even profile the Actix HTTP server.
+
+The only issue we see is the framing system. Puffin requires a global frame-based profiling phase, which collides with Meilisearch's ability to accept and answer multiple requests on different threads simultaneously.
