| <p>Arrow Java provides several building blocks. Data types describe the types of values; |
| ValueVectors are sequences of typed values; fields describe the types of columns in |
| tabular data; schemas describe a sequence of columns in tabular data, and |
| VectorSchemaRoot represents tabular data. Arrow also provides readers and |
| writers for loading data from and persisting data to storage.</p> |
