> As it was removed and renamed before, do we have any place that needs to use HashClusteredDistribution now? > HashPartitioning with subset of grouping keys satisfying ClusteredDistribution, can be a tradeoff. Since ClusteredDistribution is not strictly better than HashClusteredDistribution for all queries and vice versa, I think we should at least have a config for sending HashClusteredDistribution down as a distribution requirement, so that users can toggle the config for their queries when using ClusteredDistribution is worse than HashClusteredDistribution. -- This is an automated message from the Apache Git Service.
