**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** Writing dictionary encoded arrays using parquet spends lot of time rehashing arrays. **Describe the solution you'd like** <!-- A clear and concise description of what you want to happen. --> Use am initial capacity for the interner hashmap. This saves reallocating and shuffling around the table every time the capacity is too low (each time the size doubles). **Describe alternatives you've considered** <!-- A clear and concise description of any alternative solutions or features you've considered. --> n/a **Additional context** <!-- Add any other context or screenshots about the feature request here. --> -- This is an automated message from the Apache Git Service.
