com.gpudb.protocol.FilterByRangeRequest

All Implemented Interfaces:

org.apache.avro.generic.GenericContainer, org.apache.avro.generic.IndexedRecord

public class FilterByRangeRequest
extends Object
implements org.apache.avro.generic.IndexedRecord

A set of parameters for GPUdb.filterByRange.

Calculates which objects from a table have a column that is within the given bounds. An object from the table identified by tableName is added to the view viewName if its column is within [lowerBound, upperBound] (inclusive). The operation is synchronous. The response provides a count of the number of objects which passed the bound filter. Although this functionality can also be accomplished with the standard filter function, it is more efficient.

For track objects, the count reflects how many points fall within the given bounds (which may not include all the track points of any given track).

Constructor Detail

FilterByRangeRequest

public FilterByRangeRequest()

Constructs a FilterByRangeRequest object with default parameters.

FilterByRangeRequest

public FilterByRangeRequest(String tableName,
                            String viewName,
                            String columnName,
                            double lowerBound,
                            double upperBound,
                            Map<String,String> options)

Constructs a FilterByRangeRequest object with the specified parameters.

Parameters:

tableName - Name of the table on which the filter by range operation will be performed, in [schema_name.]table_name format, using standard name resolution rules. Must be an existing table.

viewName - If 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 ''.

columnName - Name of a column on which the operation would be applied.

lowerBound - Value of the lower bound (inclusive).

upperBound - Value of the upper bound (inclusive).

options - Optional parameters.

• CREATE_TEMP_TABLE: If TRUE, a unique temporary table name will be generated in the sys_temp schema and used in place of viewName. 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:
  • TRUE
  • FALSE
  The default value is FALSE.
• COLLECTION_NAME: [DEPRECATED--please specify the containing schema for the view as part of viewName and use GPUdb.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.

The default value is an empty Map.
