    Hello @aljoscha , 
    As I mentioned in last comment, I will reimplement it with [Guava CacheBuilder](http://docs.guava-libraries.googlecode.com/git/javadoc/com/google/common/cache/CacheBuilder.html).
One question is about Flink self-memory management, does CacheBuilder get memory from Flink
or JVM directly? As I understand, HeapWindowBuffer allocates memory from Flink. Is there any
data structure like cachedMap in Flink?
