• source code
  • Not at hand, but better than nothing: Free software advocates have long known that if you can't inspect a system, you're held prisoner by it. Yet this applies not just to the layers that programmers currently code on, but also into new and more abstract frontiers. A black box that you can't ask to explain itself is a dangerous and probably poorly operating device or system. (#)
  • If source data is is time-versioned, code is versioned, and not reliant on side effects, you can re-discover context.
• logs
  • all in one place
  • limited query-ability
  • schema-on-read if you have a schema parser like in Loggly
• within database
  • readily queryable along OLTP data (easy to join or filter by)
• separate event store like Druid
  • great queryability (like SQL)
  • horizontally scalable (and separate components are independently scalable based on need)
  • SQL connector and charting into things like Tableau or Superset
