rebuildRange
public final void rebuildRange(Void ctx, RebuildRangeRequest request, Observer<com.google.protobuf.Empty> observer) Rebuild range The back filler has to be enabled for this purpose. The back filling process does not remove data but just overwrites it. That means that if the parameter replay returns less parameters than originally stored in the archive, the old parameters will still be found in the archive. It also means that if a replay returns the parameter of a different type than originally stored, the old ones will still be stored. This is because the parameter archive treats parameter with the same name but different type as different parameters. Each of them is given an id and the id is stored in the archive.

getParameterSamples
public final void getParameterSamples(Void ctx, Archive.GetParameterSamplesRequest request, Observer<Pvalue.TimeSeries> observer) Get parameter samples This divides the query interval in a number of intervals and returns aggregated statistics (max, min, avg) about each interval. This operation is useful when making high-level overviews (such as plots) of a parameter's value over large time intervals without having to retrieve each and every individual parameter value. By default this operation fetches data from the parameter archive and/or parameter cache. If these services are not configured, you can still get correct results by specifying the option ``source=replay`` as detailed below.

getParameterRanges
public final void getParameterRanges(Void ctx, GetParameterRangesRequest request, Observer<Pvalue.Ranges> observer) Get parameter ranges A range is a tuple ``(start, stop, value, count)`` that represents the time interval for which the parameter has been steadily coming in with the same value. This request is useful for retrieving an overview for parameters that change unfrequently in a large time interval. For example an on/off status of a device, or some operational status. Two consecutive ranges containing the same value will be returned if there was a gap in the data. The gap is determined according to the parameter expiration time configured in the Mission Database.

getArchivedParametersInfo
public final void getArchivedParametersInfo(Void ctx, GetArchivedParametersInfoRequest request, Observer<ArchivedParametersInfoResponse> observer) Get information about the archived parameters. Each combination of (parameter name, raw type, engineering type) is assigned a unique parameter id. The parameters are grouped such that the samples of all parameters from one group have the same timestamp. For example all parameters extracted from one TM packet have usually the same timestamp and are part of the same group. Each group is assigned a unique group id. A parameter can be part of multiple groups. For instance a parameter appearing in the header of a packet is part of all groups made by inherited containers (i.e. each packet with that header will compose another group). For each group, the parameter archive stores one common record for the timestamps and individual records for the raw and engineering values of each parameter. If a parameter appears in multiple groups, retrieving its value means combining (time-based merge operation). The records beloging to the groups in which the parameter appears. The response to this method contains the parameter id, name, engineering type, raw type and the groups of which this parameter is part of.

getArchivedParameterSegments
public final void getArchivedParameterSegments(Void ctx, GetArchivedParameterSegmentsRequest request, Observer<ArchivedParameterSegmentsResponse> observer) For a given parameter id, get the list of segments available for that parameter. A segment contains multiple samples (maximum ~70 minutes) of the same parameter.
