    query : TSStorageDBQuery;
  };
Arguments
query
The query to find the requested time series data in the DB.

GetDataTSStorageDBReply

type GetDataTSStorageDBReply :=
  mkGetDataTSStorageDBReply@{
    query : TSStorageDBQuery;
    data : TSStorageDBData;
  };
Arguments
query
The query to find the requested time series data in the DB.
data

RecordDataTSStorageDBRequest

type RecordDataTSStorageDBRequest :=
  mkRecordDataTSStorageDBRequest@{
    query : TSStorageDBQuery;
  };
Arguments
query

The query that expresses the addition of the time series data into the DB.

type RecordDataTSStorageDBReply :=
  mkRecordDataTSStorageDBReply@{
    query : TSStorageDBQuery;
    success : Bool;
  };
Arguments
query
The query that expresses the recording of the time series data into the DB.
success
The success of the operation, indicating if the data was stored successfully or not.

DeleteDataTSStorageDBRequest

type DeleteDataTSStorageDBRequest :=
  mkDeleteDataTSStorageDBRequest@{
    query : TSStorageDBQuery;
  };
Arguments
query
The query that expresses the deletion of the time series data from the DB.

type DeleteDataTSStorageDBReply :=
  mkDeleteDataTSStorageDBReply@{
    query : TSStorageDBQuery;
    success : Bool;
  };
Arguments
query
The query that expresses the deletion of the time series data from the DB.
success
The success of the operation, indicating if the data was deleted successfully or not.

DataChangedTSStorageDB

type DataChangedTSStorageDB :=
  mkDataChangedTSStorageDB@{
    query : TSStorageDBQuery;
    data : TSStorageDBData;
    timestamp : EpochTimestamp;
  };
Arguments
query
The query that expresses the change of the time series DB.
data
The changed time series data.
timestamp
The wall clock time of the moment the data was changed.
