VectorSchemaRoot

✓ org.apache.arrow.vector.VectorSchemaRoot

Creates an Arrow vector schema root and populates an integer vector.

import org.apache.arrow.vector.VectorSchemaRoot; import org.apache.arrow.vector.IntVector; import org.apache.arrow.memory.RootAllocator; public class Example { public static void main(String[] args) { try (RootAllocator allocator = new RootAllocator(); VectorSchemaRoot root = VectorSchemaRoot.create(allocator)) { IntVector intVector = (IntVector) root.getVector("intField"); intVector.allocateNew(10); intVector.set(0, 42); intVector.setValueCount(10); } } }

Debug

Known issues

gotchaMemory management requires careful handling of allocators and closing resources.

fix

Always use try-with-resources or explicitly close allocators and vectors.
