Member Function Documentation

Result< ArrowArrayStream > iceberg::MetadataScanTaskReader::Open

Open a task and return an Arrow C stream for its projected rows.

Batches are built on demand. The stream retains its input data and can outlive this reader and the task; each call starts an independent read.
