DATAX 默认配置 占用主机cached很大

你好 主机内存64G 默认配置 执行完一次数据迁移 free -g cached 占用很大

Start by reproducing one data migration with the default DataX configuration on a host with comparable memory, then inspect the migration process's memory behavior and configuration. The issue does not name files, tests, or entry points, so first identify the relevant default settings and determine whether the large cached value is expected or indicates a leak; done should include a confirmed cause and an appropriate fix or documented explanation.
