Motivation

This PR adds analytics the SFN provider to help ascertain usage of the new JSONata and Variable workflows.

Changes

  • Add a static analyser that will check for:
    • Any variable sampling or assigning of variables
    • The query language being used by the state machine definition
  • Metrics have been added that will record whether a sfn uses JSONata or variable workflows, respectively.

Testing

  • Added unit tests to ensure the static analysis is correct.

We want to set this flag to true if there is an Assign or if any variable sampling has been used.

Looking good from a SFN standpoint!

You can probably prune this logic if the flag is already set

yeah data 👍

I would skip the try/catch on the metric counter unless we have a good reason from the SFN analyser side.

...-core/localstack/services/stepfunctions/asl/static_analyser/usage_metrics_static_analyser.py
analyser = UsageMetricsStaticAnalyser()
analyser.analyse(definition=definition)

try:

Do we need the try/catch here? has_jsonata is just a getter and we can expect the counters to work (we're not using try/catch anywhere else)
if we want to be as defensive, then we should rather cover the analyse step.

We didn't want the metrics collection to be the reason why SFN was failing. Will just surround the whole block in a try-catch rather

OK wrapped the whole process in a try-except
