   ### Bug
   - What happen?
   If possible, provide a way for reproducing the error. e.g. demo application, component version.
   
   Aggregate workers and persistence workers own two cache collections. One of the their use to cache the data merged by streaming data. The other one is waiting to export aggregated when persistence timer scanning. But if persistence speed can not catch streaming speed, the cache collection's size will increased too large. Collector will crash down when all the workers cached huge data.
