AWS EventBridge - Customize s3 event pattern

Question

I have a s3 bucket with EventBridge events enabled and I have the following bucket structure.

s3://bucket/db/table/LOAD00001.csv

I need to create an event pattern that will identify all new files that contains "LOAD" in the filename.

My event pattern looks like:

  {
      "source": ["aws.s3"],
      "detail-type": ["Object Created"],
      "detail": {
        "bucket": {
          "name": [{
            "suffix": "-landing"
          }]
        },
        "object": {
          "key": ["*LOAD*"]
        }
      }
    }

I have tried some combinations using prefix and sufix but no success yet.

Answer 1

Event content filtering does not support wildcard pattern matching.

If prefix or suffix matching does not work, consider overfetching and using the event target to screen out unwanted events.

"key": [{"prefix": "LOAD"}]
