## Which issue does this PR close? ## Rationale for this change Current Comet unified memory pool is a greedy pool. One thread (consumer) can take a large amount of memory that causes OOM for other threads, especially for aggregation. ## What changes are included in this PR? Added a fair version of unified memory pool similar to DataFusion `FairSpilPool` that caps the memory usage at `pool_size/num` The fair unified memory pool is the default for off-heap mode with this PR ## How are these changes tested?
