A sink doesn't make allocations so I wouldn't expect to see any there. Sources may make allocations and it depends on the source. For example, a "scan" source will make allocations. However, a scan node will use the scan options to get the memory pool (this is somewhat unfortunate and I'd like to

Would this also explain the lack of allocations, reallocations or frees when creating a pipeline with just a source and a sink? For example, we do not see logs for a regular source, a table source node, or a streaming file reader node (using RecordBatchFileReader and MakeReaderGenerator) to gen
