It’s shorter sprint. Mikolaj is out for the first week.

1. NISSAN :URGENT:

   • Updates API

     • TODO Works on Staging @Marcin

       • Pipeline for whole countries doesn’t fail.
       • Fresh data available

     • TODO Remove deleted records @Marcin

       • If a record has been marked as deleted, it should not appear in patches downloaded from Updates API.

     • TODO Works on Production and sandbox @Marcin

       • API deployed
       • Pipeline deployed
       • Pipeline for whole countries doesn’t fail.
       • Fresh data available

   • TODO Test embedded on Hardware, measure RAM usage and Disk usage @Mikolaj

     • Japan data only
     • How much RAM
     • Replay production-data
     • Does not crash when run under stress (requests made via HTTP not via UI).
     • Use production requests for Japan.
     • Start and peak RAM usage known under stress and under “normal” usage.
     • Peak CPU usage known under “normal” usage.
     • Report containing the ^ findings.

   • TODO How often JP data changes and how important are the changes @Dominik -> @Marcin

     Do we need a better update mechanism than including in the APK?

     • Reviewed Dominik’s report.
     • Make it so it’s understandable by NISSAN
     • Ask for a meeting

   • TODO Deploy IPC to production (a-z sort + translations) @Bartek

   • TODO Fix PP latency problems @Mikolaj

     • Measure.
     • Fix: HPA?
     • CDN

2. Maintenance

   • TODO Push through OAuth docs!! @Marcin

     • Available on production

   • TODO Deploy conrad-proxy v3+ to sandbox + production @Marcin

     Changes to tiers, values etc.

   • TODO conrad-proxy add X-AutoStage-Manufacturer + X-AutoStage-Make @Bartek

     • conrad-proxy generated ^ extra headers and passes them to services

     • X-AutoStage-Manufacturer taken from mfgid

     • X-AutoStage-Make taken from conrad-proxy configuration (auth.json), based on mfgid

     • Add tests in .yaml format

       { "mfgids": { "FFFF01": { "manufacturer": "Daimler", "secret": "FFFF01", } }, [...] }

     • conrad-proxy is backwards-compatible and supports the old auth.json format

     • Deployment changes the structure of configuration data in secrets.yaml

   • TODO Broadcasts: Spikes to 6s on production in Netherlands @Bartek

     https://xperi.slack.com/archives/C0EQC16N8/p1711561116150939

     • How many requests per second during spikes?
     • Are these particular requests unusually slow when made separately? Is curl with this request slower than other locations?

   • TODO Release notes update @Marcin

     • Added, Fixed etc.
     • Make backwards compatible (ADD -> Added, NEW -> Added, FIX -> Fixed)
     • Support multiple paths (e.g. Added `/v1/broadcasts`, `v1/broadcasts/id/live`) Or think of a better way to express that.
     • Announce to the team

3. BMW - China

   • TODO Metrics in Playgrounds (Prometheus + Grafana) @Bartek

   • TODO TTL for live data in Redis in China @Mikolaj

     • Live API returns an extra header (using TTL redis command)?
       • /v1/broadcasts/123/live?debug=true
       • Respond with X-Debug-Redis-TTL: 2000 if debug query string param is true. Value in ms.
     • Re-distributor passes debug=true when querying Live API and sets TTL in Redis accordingly.
