Prometheus is a time-series database. It records numeric metrics only, and it records them at periodic scrape times. "The value of metric M at time T1 was M1. The value of metric M at time T2 was M2". In other words, it stores *samples* of *continuous* data.
If you want to record details of individual *events* - like attributes belong to a specific batch - then Prometheus is not the right tool for the job. Look at Loki or Elasticsearch/Opensearch instead.
