Simulated Step Functions

Yulin runs Step Functions state machines in the test process. Amazon States Language tasks invoke simulated services, waits and retries use the simulation clock, and tests can inspect execution history.

トークン認証が必要な Lambda MicroVMs サイトを起動し、指定した期間後に停止する仕組みを、StepFunctions の SDK 統合と JSONata だけで作ってみました。Lambda 関数は使いません

Many apps work well as part of a workflow and the managed approach for this on AWS typically involves Step Functions.
AWS Step Functions adds new AWS service integrations automatically, starting with AWS Lambda MicroVMs - AWS

It's Throwback Thursday! I came across this old post, www.shiftwiki.nl/awstoolkitfo..., for which I started with the AWS toolkit for VSCode, decided to do the 10 minute tutorial for step functions and the rest is history ;-).

最近仕事でまたまたAWS StepFunctionsを使うことがあって、せっかくなら~でJSONata形式で実装した。

JSONPath形式と違ってunixtimeの計算とかもあっさりやれるんでDynamoDBのttlのupsertとか楽チン。

既存JSONPathモノもJSONataにするか?って思ったけど書き方がだいぶ違うので段階的にってのは無理そう。

StepFunctionsに入門してみた。
タスク同士を繋げるクエリ言語として割と最近JSONataという言語が追加されたらしく、最初混乱したけど、JSONPathよりも更に柔軟な形式のクエリ言語も使えるようになったことで、これまでLambdaが必要だった部分がStepFunctionsだけで完結出来る範囲が広がったということなのかな。

I've just built a first stab at an instant converter between JSONPath and JSONata ASL.

Still some corner cases missing, but does most of the work.
