> ``` > batches = [batch1, batch2, batch3] > > iterator = random choose one batch from batches > ``` I am afraid this won't help as `peakmem` counts the overall memory used, by keeping a reference to all batches, they will be always counted in memory and we won't be able to see the real peakmem for iter-based UDF usage. That's the reason for replay from file when testing for `peakmem`. But then this could introduce disk I/O cost that will affect the `time*` measurement. Let me try other ways, possibly try `mem*` instead of `peakmem*` to see if that helps. -- This is an automated message from the Apache Git Service.
