Changes for version 0.033 - 2017-10-12

  • Added
    • Added Graphite time series adapter. Now `yts` can read/write time series from the Graphite system and related subsystems. The write function is compatible with the "line" protocol, so any databases that understand Graphite's line protocol can be written to.
    • Added --start and --end options to yts command to constrain the time series returned to a specific date/time range.
  • Fixed
    • Fixed the `yts` time series format. Now there is only the "metric" to identify the time series, which for some time series databases may contain abstractions like "database" and "column".
    • Fixed nulls appearing in Graphite time series.
