4442: Send custom task r=ManyTheFish a=irevoire
This PR has already been merged on main but was supposed to be merged on `release-v1.7.0` thus we need to merge it a second time; sorry 😓
### This PR implements the necessary parameters for the High Availability
Introduce a new CLI flag called `--experimental-replication-parameters` that changes a few behaviors in the engine:
- [The auto-deletion of tasks is disabled](https://specs.meilisearch.com/specifications/text/0060-tasks-api.html#_2-technical-details)
- Upon registering a task, you can choose its task ID by sending a new header: `TaskId: 456645`. It must be a valid number, which must be superior to the last task id ever seen.
- Add the ability to « dry-register » a task. That means meilisearch will answer to you with a valid task ID like everything went well, but won’t actually write anything in the database. To do that, you need to use the `DryRun: true` header.
- Specification’s here: https://github.com/meilisearch/specifications/pull/266

4418: Output logs to stderr r=dureuill a=irevoire
Output the logs to `stderr` instead of `stdout`. This was introduced in the `v1.7.0-rc.0` and is a bug; logs should always be outputted to stderr.
Fix#4419

4410: Implement the experimental log mode cli flag and log level updates at runtime r=dureuill a=irevoire
# Pull Request
This PR fixes two issues at once because they’re highly correlated in the codebase.
## Related issue
Fixes https://github.com/meilisearch/meilisearch/issues/4415
Fixes https://github.com/meilisearch/meilisearch/issues/4413
## What does this PR do?
- It makes the fmt logger configurable to output json or human-readable logs (like we already do today)
- It moves the fmt logger under a `reload` layer so we can update its targets at runtime
- Add the possibility to stream logs in the json mode
- Adds an analytics for the new CLI flag

4350: Make several indexing optimizations r=Kerollmops a=ManyTheFish
# Summary
Implement several enhancements to reduce the indexing time.
# Steps
- Compute the indexing chunk size dynamically based on the available threads and the data size
- Remove the merging step before the writing step and merge at the writing time
- Remove append function
- Make Facet search indexing incremental
# Running Indexing process
## `main`
Each type of data is written after a merging phase:
> Highlighted parts are the writings
## `remove-merging-phase-from-indexing`
When the extraction of a chunk is finished, the data is written:
> Highlighted parts are the writings
## Related
This PR removes the appending writes on several indexing parts, which may fix https://github.com/meilisearch/meilisearch/issues/4300. However, all of the appending writes are not removed. There are 2 remaining calls that could trigger this bug:
- When [putting embedders in the settings](b6fc181993/milli/src/update/settings.rs (L996))
- when [bulk indexing the facets](b6fc181993/milli/src/update/facet/bulk.rs (L150))

4391: Tracing r=dureuill a=irevoire
# Pull Request
- [ ] Hide the parameters of the process batch
- [x] Make actix-web trace every call on every route
- [x] Remove all `env_logger`/`logs` dependencies
- [x] Be able to enable or disable the memory measurement using the `/logs` route parameters
See the following product discussion: https://github.com/orgs/meilisearch/discussions/721
Supersedes https://github.com/meilisearch/meilisearch/pull/4338
## Related issue
Fixes https://github.com/meilisearch/meilisearch/issues/4317
## What does this PR do?
Update the format of the logs from:
```
[2024-02-06T14:54:11Z INFO actix_server::builder] starting 10 workers
```
to
```
2024-02-06T13:58:14.710803Z INFO actix_server::builder: 200: starting 10 workers
```
First, run meilisearch with the route enabled via the feature flag:
- `cargo run --experimental-enable-logs-route`
- Or at runtime by sending the following payload:
```
curl \
-X PATCH 'http://localhost:7700/experimental-features/' \
-H 'Content-Type: application/json' \
--data-binary '{
"logsRoute": true
}'
```
Then gather data from meilisearch by calling for example:
```
curl \
-X POST http://localhost:7700/logs \
-H 'Content-Type: application/json' \
--data-binary '{
"mode": "fmt",
"target": "milli=trace"
}'
```
Once your operation is over, tell meilisearch to stop the route:
```
curl \
-X DELETE http://localhost:7700/logs
```
----
In the case you’re profiling code, you will be interested by the next command that converts the output of the route to a format that the firefox profiler can understand.
```bash
cargo run --release --bin trace-to-firefox -- 2024-01-17_17:07:55-indexing-trace.json
```
Then go to https://profiler.firefox.com and load it.
Note that we can also share the profiles using the https://share.firefox.dev website.
