### What
The heaviest requests we serve are the register and metrics POSTs from
our SDKs/clients.
This PR adds ratelimiting to /api/client/register, /api/client/metrics,
/api/frontend/register and /api/frontend/metrics with a default set to
6000 requests per minute (or 100 rps) for each of the endpoints.
It will be overrideable by the environment variables documented.
### Points of discussion
@kwasniew already suggested using featuretoggles with variants to
control the rate per clientId. I struggled to see if we could
dynamically update the middleware after initialisation, so this attempt
will need a restart of the pod to update the request limit.
## About the changes
This small improvement aims to help developers when instantiating
services. They need to be constructed without injecting services or
stores created elsewhere so they can be bound to the same transactional
scope.
This suggests that you need to create the services and stores on your
own
This fixes a return type error by changing the logic of
`extractUsernameFromUser` to never return undefined.
In the previous code, `user` could be truthy, but that doesn't mean
`email` or `username` were defined. This assumes we always fallback to
"unknown" in those scenarios.
This PR is the first step in separating the client and admin stores.
Currently our feature toggle services uses the client store to serve
multiple purposes.
Admin API uses the feature toggle service to serve both the feature
toggle list and playground features, while the client API uses the
feature toggle service to serve client features. The admin API can
change often and have very different requirements than the client API,
which changes infrequently and generally keeps the same stable structure
for long periods of time. This architecture is error prone, because when
you need to make changes to the admin API, you can very easily affect
the client API.
I aim to put up a stone wall between the two APIs. Complete separation
between the two APIs, at the cost of some duplication.
In this PR I have created a feature oriented architecture for client
features and disconnected the client API from the feature toggle
service. It now goes through it's own service to it's own store. For
feature toggle service I have duplicated and replaced the functionality
that serves /api/admin/features, I have kept a lot of the ugliness in
the code and haven't removed anything in order to avoid breaking
changes.
Next steps:
* Move playground to admin API
* Remove client-feature-toggle-store from feature-toggle-service
## About the changes
This splits the interfaces for import and export, especially because the
import functionality has to be replaced in enterprise repo.
This is a breaking change because of the service renames, but I'll have
the PR for the other repository ready so we reduce the time to fix. I
intentionally avoided doing it backward compatible because of time.
https://linear.app/unleash/issue/2-1494/re-order-message-banners
- Re-orders message banners to fit into this logic:
>1. Maintenance banner
>2. External message banner(s) - Most likely coming from Unleash
>3. Internal message banner(s)
- Renames the feature flag to better reflect the feature behavior;
- Lays a basic skeleton structure for this new feature;
As part of more telemetry on the usage of Unleash.
This PR adds a new `stat_` prefixed table as well as a trigger on the
events table trigger on each insert to increment a counter per
environment per day.
The trigger will trigger on every insert into the events base, but will
filter and only increment the counter for events that actually have the
environment set. (there are events, like user-created, that does not
relate to a specific environment).
Bit wary on this, but since we truncate down to row per (day,
environment) combo, finding conflict and incrementing shouldn't take too
long here.
@ivarconr was it something like this you were considering?
This PR cleans up and refactors the feature-strategy-store method
getFeatureOverview to join on the new table and attempts to make the
function more readable by extracting some of the logic into separate
functions. Keeping the LastSeenMapper for now in case there is a reason
to use it for the other endpoints.
## About the changes
Segment changes in predata and data columns were both showing the new
segments list
Adds formatting of what's changed with segments to feature strategy
update events, so when a user changes the strategy from using
constraints, to using segments instead, it's communicated in event
updates
results in:
admin updated
[sample-toggle](http://localhost/projects/default/features/sample-toggle)
in project [default](http://localhost/projects/default) by updating
strategy Sample Strategy in development constraints from [userId is one
of (1,2,3)] to empty set of constraints; segments from empty set of
segments to (1)
Closes #
#4912
### Important files

## Discussion points
This is an SR least effort PR - we should plan a task where we look at
how to render this list of segments in a more comprehensible way (it's
just rendering ids now)
Fixes an issue where SSO group sync would delete a syncable group that a
user was manually added to
## Discussion points
Is this the longterm fix for this? Or would we want another column in
the mapping table for future-proofing this?
## About the changes
This transactional implementation decorates a service with a
transactional method that removes the need to start transactions in the
method using the service.
This is a gradual rollout with a feature toggle, just because
transactions are not easy.

I added the events that I thought were relevant based on my own
discretion. Know of any event we should add? Let me know and I'll add it
🙂
For now I only added these events to the new Slack App integration, but
we can add them to the other integrations as well since they are now
supported.
The event formatter was refactored and changed quite a bit in order to
make it easier to maintain and add new events in the future. As a
result, events are now posted with different text. Do we consider this a
breaking change? If so, I can keep the old event formatter around,
create a new one and only use it for the new Slack App integration.
I noticed we don't have good 404 behaviors in the UI for things that are
deleted in the meantime, that's why I avoided some links to specific
resources (like feature strategies, integration configurations, etc),
but we could add them later if we improve this.
This PR also tries to add some consistency to the the way we log events.
## About the changes
In our staging setup, we create ad-hoc environments and import Unleash
state from production. After unleash is deployed on such environment,
the import job kicks in and feeds Unleash instance with feature flags
from production.
Between Unleash being up and running and the import job running, some
applications start polling Unleash. They get an empty feature toggle
list with `meta.revisionId=0`. Then apps use this as part of `eTag`
header in subsequent requests. Even though after import Unleash server
finally has toggles to serve, it doesn't because it calculates _max
revision id_ based on toggle updates (not null `feature_name` column in
query) or `SEGMENT_UPDATED`.
This change adds an extra condition to query so feature toggles import
is considered something that should invalidate the cache.
This commit changes our linter/formatter to biome (https://biomejs.dev/)
Causing our prehook to run almost instantly, and our "yarn lint" task to
run in sub 100ms.
Some trade-offs:
* Biome isn't quite as well established as ESLint
* Are we ready to install a different vscode plugin (the biome plugin)
instead of the prettier plugin
The configuration set for biome also has a set of recommended rules,
this is turned on by default, in order to get to something that was
mergeable I have turned off a couple the rules we seemed to violate the
most, that we also explicitly told eslint to ignore.
## About the changes
This fixes a bunch of openHandles from our tests
I've used this script to find out the ones that leave them:
`find src -name "*.test.ts" -printf "%f\n" | xargs -i sh -c "echo =====
{} && yarn test {}"`
If there's an issue, the script will halt and the last filename will be
the one that has to be fixed.
Each commit fixes one problem so it's easy to review
## About the changes
Add partial index on events by announced. This should help avoid `Seq
Scan on events` when the majority of events are announced=true

## About the changes
When the events table is large we might be doing a full table scan
searching for unannounced events. We spotted it due to a performance
alert and confirmed in AWS performance insights
The proposal is to limit this operation to 500 events (rule of thumb)
per round
f82ae354eb/src/lib/services/index.ts (L141-L147)
and also ignore the events older than a day (because it seems
reasonable)
## Discussion points
**Idea**: split the `events` table into `recent_events` and
`historical_events`. Recent can be anything from a day/week/month. This
would help with recurrent queries that rely on recent data from the
event's table such as optimal 304 calculation or event this scheduled
task that sends unannounced events.
https://linear.app/unleash/issue/2-1403/consider-refactoring-the-way-tags-are-fetched-for-the-events
This adds 2 methods to `EventService`:
- `storeEvent`;
- `storeEvents`;
This allows us to run event-specific logic inside these methods. In the
case of this PR, this means fetching the feature tags in case the event
contains a `featureName` and there are no tags specified in the event.
This prevents us from having to remember to fetch the tags in order to
store feature-related events except for very specific cases, like the
deletion of a feature - You can't fetch tags for a feature that no
longer exists, so in that case we need to pre-fetch the tags before
deleting the feature.
This also allows us to do any event-specific post-processing to the
event before reaching the DB layer.
In general I think it's also nicer that we reference the event service
instead of the event store directly.
There's a lot of changes and a lot of files touched, but most of it is
boilerplate to inject the `eventService` where needed instead of using
the `eventStore` directly.
Hopefully this will be a better approach than
