Fixed an out-of-heap memory exception problem caused by excessive disk persist due to a memory byte estimate of thetasketch type. I think this fix is useful when we have this problem in our production environment. After the second adjustment function is turned on, the performance of the ingestion task is affected to some extent. New feature: Dynamically resizes memory bytes based on aggregate cardinalities(for example:Thetasketch metric). Add two parameters to the Peon configuration(MiddleManager runtime.properties): 1. -DADJUSTBytesinMemoryFlag =true # Whether to turn on tuning policies; 2. - DadjustBytesInMemoryPeriod = 200 # timing adjustment period, millisecond unit.
