README
my attempt at setting up a lambda that is written in scala but uses graalvm to create a single, static binary + a custom
aws runtime (see [`Bootstrap.scala`](./src/main/scala/example/Bootstrap.scala))
1. create a bucket to store the lambda code
2. run `./deployment/deploy.sh `
3. wait
4. go into the aws console and invoke the function via the `Test` tab
### Results
(not scientific at all, first row is non-coldstarts, second row are the coldstarts, in milliseconds):
Loadtest:
```sh
npx artillery quick --count 20 --num 1000
```
Query:
```
filter @type = "REPORT"
| parse @log /\d+:\/aws\/lambda\/(?.*)/
| stats
count(*) as invocations,
pct(@duration+coalesce(@initDuration,0), 0) as p0,
pct(@duration+coalesce(@initDuration,0), 25) as p25,
pct(@duration+coalesce(@initDuration,0), 50) as p50,
pct(@duration+coalesce(@initDuration,0), 75) as p75,
pct(@duration+coalesce(@initDuration,0), 90) as p90,
pct(@duration+coalesce(@initDuration,0), 95) as p95,
pct(@duration+coalesce(@initDuration,0), 99) as p99,
pct(@duration+coalesce(@initDuration,0), 100) as p100
group by function, ispresent(@initDuration) as coldstart
| sort by coldstart, function
```
### for local testing
1. `./deployment/build.sh`
2. `docker build -t docker-lambda .`
3. `docker run -p 9000:8080 docker-lambda:latest`
4. Send a test event: `curl "http://localhost:9000/2015-03-31/functions/function/invocations" -d 'Hello world!'`
