## Feature Notes

- back-end software: SeisComP
- The IRISWS availability implementation truncates the timespans of the returned data extents and segments to the requested start and end times (if any). This implementation truncates the start and end time only for the request format. The text, geocsv and json format will return the exact time windows extracted from the waveform archive.
- orderby parameter not implemented for query request (to save memory the data is streamed from the database, to support the merge operation, the data needs to be ordered by time)
- additional request parameters:
  - excludetoolarge (query): boolean, default: true
