Hi, We ran a few tests with apache kafka 0.10.1.1. We use a Topology with only one processor and a KVStore configured as persistent backed by rocksdb 4.9.0. Each events received are stored using the method put(key, value) and in the punctuate method, we iterate over all entries with all(), processing them and deleting them with delete(key). Then after a few days, the jvm crashed due to lack of memory. Visualvm or jmap doesn't show anything, so my guesses were there was a memory leak in rocksdb. We configured the KVStore to be in memory and as you can see in picture 2, the memory is stable. I didn't run the same test with a newer version of rocksdb yet. Any thoughts ? Regards,
Pierre
