> @XorSum I wonder why do we need to do this manual batch split, the join algorithm itself already have batch_size handling logic, there is bug in it? > > https://github.com/apache/auron/blob/10517904367ae91cbe88ca8635bffd010601f201/native-engine/datafusion-ext-plans/src/joins/smj/full_join.rs#L55-L57 Thanks for the comment! I do not yet understand how the join batch_size handling logic works, however I did find a reproducible bug(#1693). An extremely large batch (100 million rows) is generated after the join operation, and lead to the `OversizedAllocationException`. -- This is an automated message from the Apache Git Service.
