LTSV

What is LTSV?

  • an extended format of TSV
  • you can label each field like this:
label:value<TAB>label:value<TAB>label:value ...

Why LTSV?

  • very simple!
  • flexibility for expanding
  • you can insert a record with new label without changing any metadata
  • very easy to generate log
  • In Apache HTTP Server, LogFormat directive can generate LTSV format log
  • nginx can do as well
  • why do you generate log in json format, or convert the log into json format?

  • very easy to parse log

    • because it's just TSV!
    • you can parse LTSV with standard unix commands e.g. cut, split, etc.
    • do you like to parse json without library?
