### Is your feature request related to a problem or challenge? Currently we save indices to the batch always as `u64` in the `HashTable` and in the `next` `Vec`. If we have less than `u32:MAX` (4.2B, i.e. most of the time) items, we can store them as `u32` - which should make it fit more easily in the CPU cache. ### Describe the solution you'd like * Implement optimization to store indices as `u32` if possible. * Run benchmarks ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
