Flink hash collision on user-specified id
WebOne method for resolving collisions looks into the hash table and tries to find another open slot to hold the item that caused the collision. A simple way to do this is to start at the original hash value position and then move in a sequential manner through the slots until we encounter the first slot that is empty.

WebFeb 18, 2024 · Looking into Flink’s code, we can find this function: public static int computeOperatorIndexForKeyGroup ( int maxParallelism, int parallelism, int keyGroupId) { return keyGroupId * parallelism / maxParallelism; } Its purpose is to distribute all Key Groups to the actual operators. WebCollision attacks. An attacker finds two files M (Malicious), S (Safe) that have the same hash. Here the attacker can choose M and S freely. Second pre-image attacks. The attacker is given a file C (Common), and has to find a second file M that has the same hash as file C. Notice that the attacker cannot choose C; it is given to him.
