### Search before asking - [x] I searched in the [issues](https://github.com/apache/paimon-cpp/issues) and found nothing similar. ### Motivation Paimon C++ currently requires a `BatchReader` to outlive its returned `ReadBatch`, because batch buffers may use Arrow or ORC memory pools owned by the reader. This lifetime coupling is inconvenient for downstream engines and can cause invalid memory access if the reader is destroyed first. ### Solution Retain the required memory-pool smart pointers in the root `ArrowArray,` so the batch can safely outlive its reader. Consumers must keep, move, and release the complete root `ArrowArray`. Moving individual child arrays out of it is unsupported because child arrays do not retain the memory-pool lifetime independently. ### Anything else?
