The outdated data is useless and costly, we need a TTL(Time-To-Live) management mechanism to prevent the dataset from growing infinitely. +This proposal introduces Partition TTL Management policies to hudi, people can config the policies by table config directly or by call commands. With proper configs set, Hudi can find out which partitions are outdated and delete them. +## Background +TTL management mechanism is an important feature for databases. Hudi already provides a delete_partition interface to delete outdated partitions. However, users still need to detect which partitions are outdated and call `delete_partition` manually, which means that users need to define and implement some kind of TTL policies and maintain proper statistics to find expired partitions by themself. As the scale of installations grew, it's more important to implement a user-friendly TTL management mechanism for hudi.
