余談
TISという会社に所属している、小西です。
昨年は、Re:Invent2019 に初めて行き、まさに「熱量」を感じる機会を得られましたが、
今年は、普通に業務で、セミナーはあまり聞けませんが、新機能をウォッチしていきたいなと思います。
3年近くサーバレスをやってきたので、サーバレスをウォッチしていきたい。
概要
Re:Invent 2020 で、High Performance Lambdaがリリースされ、メモリー上限が10Gとなり、コア数も最大6コアになりました。
ただ、メモリー設定でどうコア数が変わるかは公開されていないので実際に確認してみました。
なお、Re:Invent 2020 で、メモリー設定が64MBステップから1MBステップに変わったのですが、
検証は、64MBステップで行っているので、正確な切り替わりポイントでない可能性があります。すいません。
結論
以下の通り、最低2コアで、3Gから2G毎にコア数が上がるようです。
これまで、1536Mまで1コアでそれ以上が2コアだったようですが、大きく変更となりましたね。
課金単位も変わりましたが、実質的に値下げと言えるかもしれませんね。
これで、LambdaでFFmpegなどでの音声・動画の変換など、長時間処理でタイム・アウトしていた処理も十分実行できそうですね。
まだ使っていませんが、AVX2もつかえるようになったのも嬉しいですよね。
追記:これまで、どこまで1コアだったのかは、あいまいなようです。クラメソさんの記事 では、 1792MBまで1コアだったようです

実施手順(メモ)
Lambdaを配置
'use strict';
let response;
const { promisify } = require('util');
const proc = require('node-proc');
exports.lambdaHandler = async (event, context) => {
const meminfo = await promisify(proc.meminfo)();
const cpuinfo = await promisify(proc.cpuinfo)();
const uptime = await promisify(proc.uptime)();
const netdev = await promisify(proc.netdev)();
return {
meminfo,
cpuinfo,
uptime,
netdev
};
};
Bash でメモリー設定を変えながらInvoke
for ((i=2; i<=160; i++))
do
aws lambda update-function-configuration --function-name lambda-proc-info --memory-size $(($i*64))
aws lambda invoke --function-name lambda-proc-info --payload '{}' $(($i*64)).json
done
jq等で加工(雑)
for ((i=2; i<=160; i++))
do
jq ".+ {memory_setting: $(($i*64))}" $(($i*64)).json > $(($i*64))-append-memorysetting.json
done
jq -s . *-append-memorysetting.json > mem-all.json
jq '[.[]| .+ {cpucount: (.cpuinfo|length)}]' mem-all.json >mem-all-addcount.json
jq "sort_by(.memory_setting)" mem-all-addcount.json >mem-all-sort.json
参考
