Ask a question, the same business logic, the same resource configuration, the memory usage of the job is very different between Flink1.9 and Flink1.12. Using jemalloc analysis, it is found that the UncompressBlockContentsForCompressionType method of rocksdb takes up more memory and runs the same time , This method occupies 200MB of memory in Flink1.9 and about 4G in Flink1.12. Have you ever encountered this phenomenon? <http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/file/t3050/1.png> <http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/file/t3050/12.png>
