BATCH_SIZE Query Option

Number of rows evaluated at a time by SQL operators. Unspecified or a size of 0 uses a predefined default size. Using a large number improves responsiveness, especially for scan operations, at the cost of a higher memory footprint.

This option is primarily for Cloudera testing, or for use under the direction of Cloudera Support.

Type: numeric

Default: 0 (meaning the predefined default of 1024)
