Session: Delete Time Series

Delete a range of time series entries using TimeSeriesFor.Delete.


TimeSeriesFor.Delete is used for the removal of time series and time series entries.

  • There is no need to explicitly delete a time series; the series is deleted when all its entries are deleted.
  • Attempting to delete nonexistent entries results in a no-op, generating no exception.


  • There are two TimeSeriesFor.Delete methods:

    • Delete a single time series entry.
      // Delete a single time-series entry
      void Delete(DateTime at);
    • Delete a range of time series entries.
      // Delete a range of time-series entries
      void Delete(DateTime from, DateTime to);
  • Parameters

    Parameters Type Description
    at DateTime Timestamp of the time series entry you want to delete.
    from (optional) DateTime? Delete the range of time series entries starting at this timestamp.
    Default: DateTime.Min
    to (optional) DateTime? Delete the range of time series entries ending at this timestamp.
    Default: DateTime.Max

| from | DateTime | Range Start (optional)
| to | DateTime | Range End (optional)
Default: DateTime.Max

  • Return Value
    No return value.

  • Exceptions

    • DocumentDoesNotExistException is thrown If the document doesn't exist.
    • Attempting to delete nonexistent entries results in a no-op and does not generate an exception.

Usage Flow

  • Open a session.
  • Create an instance of TimeSeriesFor.
  • Call TimeSeriesFor.Delete.
  • Call session.SaveChanges for the action to take effect on the server.

Usage Samples

  • Delete a single entry:

    // Delete a single entry
    using (var session = store.OpenSession())
        session.TimeSeriesFor("users/john", "HeartRates")
  • Delete a range of entries:

    // Delete a range of entries from the time series
    using (var session = store.OpenSession())
        session.TimeSeriesFor("users/john", "HeartRates")
            .Delete(baseline.AddSeconds(0), baseline.AddSeconds(9));
