Hash collision tests are in place to guard against these types of issues, which is why I don't foresee any problem in this area. To explain further, the hash table algorithm stores the raw hash values. As you've pointed out, hash collisions can occur for different keys. However, after retrieving the indices, we perform a vectorized equality check. This step allows us to resolve any hash collisions that may arise. -- This is an automated message from the Apache Git Service.
