Batch job tags don't show up everywhere

Question

When creating new AWS Batch jobs via the SubmitJob API (done in Python, boto3), I see the submitted tags show up in the AWS Batch console. Where I _don't_ see them though, is
- The DescribeJob API (done via AWS CLI, `aws batch describe-jobs ...`
- Job State change events sent to EventBridge

Is this a bug or intended behavior?

If it's intended, what is the appropriate way to tag my jobs so that Batch events have arbitrary key/value pairs that I can match EventBridge rules against?

Accepted Answer

I found a way to do solve my (EventBridge) problem using AWS Batch's `parameters` option for jobs.

This is a way to write an EventBridge rule that matches a specific parameter set for filtering purposes

```
{
  "source": ["aws.batch"],
  "detail-type": ["Batch Job State Change"],
  "detail": {
    "parameters": {
      "match_me_exactly": ["only-this-should-match"]
    }
  }
}
```
This will filter down to job state events that come from a job submitted like so
```
batch_client.submit_job(
  # other stuff here ...
  parameters={"match_me_exactly": "only-this-should-match"}
)
```

Other types of content matching can be figured out from EventBridge's docs https://docs.aws.amazon.com/eventbridge/latest/userguide/eb-event-patterns-content-based-filtering.html#eb-filtering-complex-example
