## Which issue does this PR close? - Prep work for #20465 ## Rationale for this change - Add three queries to measure the end-to-end performance of `array_agg()`, as prep work for optimizing its performance. ## What changes are included in this PR? This PR also cleans up the `data_utils` benchmark code: - Seed the RNG once and use it for all data generation. The previous coding seeded an RNG but only used it for some data, and also used the same seed for every batch, which lead to repeated data (... I assume this was not the intent?) - The previous code made `u64_wide` a nullable field, but passed `9.0` for the `value_density` when generating data, which meant that no NULL values would ever be generated. Switch to making `u64_wide` non-nullable. - Fix up comments, remove a clippy suppress, various other cleanups. ## Are these changes tested? Yes. ## Are there any user-facing changes? No. -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
