◆ filterBySeries() [1/2]

FilterBySeriesResponse kinetica.Kinetica.filterBySeries (FilterBySeriesRequestrequest_)
 inline

Filters objects matching all points of the given track (works only on track type data).

It allows users to specify a particular track to find all other points in the table that fall within specified ranges (spatial and temporal) of all points of the given track. Additionally, the user can specify another track to see if the two intersect (or go close to each other within the specified ranges). The user also has the flexibility of using different metrics for the spatial distance calculation: Euclidean (flat geometry) or Great Circle (spherical geometry to approximate the Earth’s surface distances). The filtered points are stored in a newly created result set. The return value of the function is the number of points in the resultant set (view).

This operation is synchronous, meaning that a response will not be returned until all the objects are fully available.

Parameters
request_Request object containing the parameters for the operation.
Returns
Response object containing the result of the operation.

This operation is synchronous, meaning that a response will not be returned until all the objects are fully available.

Parameters
table_nameName of the table on which the filter by track operation will be performed, in [schema_name.]table_name format, using standard name resolution rules. Must be a currently existing table with a track present.
view_nameIf provided, then this will be the name of the view containing the results, in [schema_name.]view_name format, using standard name resolution rules and meeting table naming criteria. Must not be an already existing table or view. The default value is ”.
track_idThe ID of the track which will act as the filtering points. Must be an existing track within the given table.
target_track_idsUp to one track ID to intersect with the “filter” track. If any provided, it must be an valid track ID within the given set.
optionsOptional parameters.
  • CREATE_TEMP_TABLE: If TRUE, a unique temporary table name will be generated in the sys_temp schema and used in place of view_name . This is always allowed even if the caller does not have permission to create tables. The generated name is returned in QUALIFIED_VIEW_NAME. Supported values:The default value is FALSE.
  • COLLECTION_NAME: [DEPRECATED–please specify the containing schema for the view as part of view_name and use createSchema to create the schema if non-existent] Name of a schema for the newly created view. If the schema is non-existent, it will be automatically created.
  • SPATIAL_RADIUS: A positive number passed as a string representing the radius of the search area centered around each track point’s geospatial coordinates. The value is interpreted in meters. Required parameter. The minimum allowed value is ‘0’.
  • TIME_RADIUS: A positive number passed as a string representing the maximum allowable time difference between the timestamps of a filtered object and the given track’s points. The value is interpreted in seconds. Required parameter. The minimum allowed value is ‘0’.
  • SPATIAL_DISTANCE_METRIC: A string representing the coordinate system to use for the spatial search criteria. Acceptable values are ‘euclidean’ and ‘great_circle’. Optional parameter; default is ‘euclidean’. Supported values:
The default value is an empty Dictionary.
Returns
Response object containing the result of the operation.

◆ FilterBySeriesAsync() [1/2]

async System.Threading.Tasks.Task< FilterBySeriesResponse > kinetica.Kinetica.FilterBySeriesAsync (FilterBySeriesRequestrequest_,
System.Threading.CancellationTokencancellationToken = default )
 inline

Filters objects matching all points of the given track (works only on track type data).

(async)

It allows users to specify a particular track to find all other points in the table that fall within specified ranges (spatial and temporal) of all points of the given track. Additionally, the user can specify another track to see if the two intersect (or go close to each other within the specified ranges). The user also has the flexibility of using different metrics for the spatial distance calculation: Euclidean (flat geometry) or Great Circle (spherical geometry to approximate the Earth’s surface distances). The filtered points are stored in a newly created result set. The return value of the function is the number of points in the resultant set (view).

This operation is synchronous, meaning that a response will not be returned until all the objects are fully available.

Parameters
request_Request object containing the parameters for the operation.
cancellationTokenCancellation token to cancel the operation.
Returns
Task that returns the response object containing the result of the operation.
