Maybe, we can move this part into a dedicated rule after AddTransformHintRule
(see link).

Thanks, moved to a separate rule.

This method looks repeated. If so, maybe, we can just move this method into a common place. But just move the check for BloomFilterAggregate
into shims, as I note it doesn't exist in spark3.2.
Spark 3.3/3.4:
def hasBloomFilterAggregate(agg): Boolean = {
agg.aggregateExpressions.exists( expr.aggregateFunction.isInstanceOf[BloomFilterAggregate])
}
Spark 3.2:
def hasBloomFilterAggregate(agg): Boolean = {
false
}

Updated, thanks,
Also note this doc: https://github.com/oap-project/gluten/blob/main/docs/velox-backend-limitations.md#runtime-bloomfilter. With this fix, we need to document the behavior into fallback section. Thanks! |

Looks good! Maybe, we can skip the handling and just return the original plan if spark.gluten.sql.native.bloomFilter=false
. Right?
