Data type: Boolean

Maximum DurationSpecifies the maximum elapsed time allowed to fetch data from the data source when the query runs, measured in seconds. If the value is set to zero or is blank, it means the time will be unlimited.

For usage about the property, see Limiting the Query Run Time and Number of Records.

Data type: Integer

Maximum RowsSpecifies the maximum number of rows that will be fetched from the data source when the query runs. If the value is set to zero or is blank, it means the number will be unlimited.

For usage about the property, see Limiting the Query Run Time and Number of Records.

  • default - The setting of the Push Down Group Query property on the JDBC connection where the query is created will be applied.
