This is a common practice that the lifecycle of the reusable batch is bound to the last reader state. The reason is that creating a batch is usually a heavy operation due to memory allocation. This technique is also applied to `arrow-java` to reuse the `VectorSchemaRoot` object. It is just a coincidence that other kinds of batches do not have the lifecycle issue because only dictionary-encoded data can have the view semantics. To keep the data to live longer, it is better to provide a clone method to `ColumnVectorBatch`. -- This is an automated message from the Apache Git Service.
