### Is your feature request related to a problem or challenge? ## Is your feature request related to a problem or challenge? issue: https://github.com/apache/datafusion-comet/issues/3873 Currently, datafusion comet cannot trigger datafusion native operators to spill in response to memory pressure from Spark’s task memory manager. When Spark task memory manager is under pressure, it may ask one consumer to spill so another consumer in the same task can make progress. Comet can route that request into native code, but there is currently no DataFusion interface for asking the spill-capable operator to reclaim memory in response to that external request. ## Describe the solution you'd like * We can add an interface for spill-capable operators to expose reclaim/spill behavior. ### Describe the solution you'd like _No response_ ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
