-----------------------------------
Summary: [C++] Pass schema to consuming sink node
Key: ARROW-16033
URL: https://issues.apache.org/jira/browse/ARROW-16033
Project: Apache Arrow
Issue Type: Improvement
Components: C++
Reporter: Weston Pace
Currently most consuming sink node implementations require the schema so they
can convert from ExecBatch to RecordBatch. However, the node already knows the
schema of the batches (it is the output schema of the input). By passing this
schema to the consumers we can avoid having to know the schema ahead of time
and simplify creating a sink node consumer.
