> This issue will track all the optimizations of huge partition, and all sub-tasks will be connected with this. The solution of handling huge partitions is to make it flush to HDFS directly and limit memory usage, all subtasks are as follows. > > 1. Speed up flushing partition data to HDFS. > > * [x] [Support writing multi files of single partition to improve speed in HDFS storage #396](https://github.com/apache/incubator-uniffle/pull/396) > 2. Introduce the memory usage limitation for huge partitions > > * [x] [[ISSUE-378][HugePartition][Part-1] Record every partition data size for one app #458](https://github.com/apache/incubator-uniffle/pull/458) > * [ ] Introduce storage selector strategy(to support huge partition flushed to HDFS directly) in MultipleStorageManager to replace fallback strategy > * [ ] Introduce more metrics to monitor huge partitions and so on > 3. Support split huge event into smaller multiple events concurrently to speed up flushing > > cc @jerqi @advancedxy I will create some subtasks of issues and PRs, feel free to discuss more.
