long com.cloudera.impala.planner.PlanNode.getInputCardinality ( )

The input cardinality is the sum of output cardinalities of its children. For scan nodes the input cardinality is the expected number of rows scanned.

inlineprotectedinherited

Return the offset_ details, if applicable. This is available separately from 'getNodeExplainString' because we want to output 'limit: ...' (which can be printed from PlanNode) before 'offset: ...', which is only printed from SortNodes right now.
