This is a representation of a log containing 2 records:

  • on position 1 a command: DEPLOYMENT:CREATE
  • on position 2 an event: DEPLOYMENT:CREATED referring to the record on position 1 as its source

MVP:

  • read json input
  • output some block format
  • split record into metadata section and value section
  • the record value is just printed in a pretty json format
  • the record position can be displayed in the record metadata section
  • the source record position can be displayed in the record metadata section

Nice to haves:

  • value properties that are too large should be truncated
  • the source record position can be visualized in the same way as git log --graph
  • colors can be used for the record graph and to differentiate between events/commands or even different record value types
  • value properties can be displayed in a static table instead of pretty json
  • add this to zdb
  • add a --oneline flag to represent the log in a compact way (mostly focussed on order and source graph)
