Review comment:
We should but maybe this requires more discussion and I guess it is
outside the scope of this PR. We can open the discussion in the dev list or
open up a follow-up JIRA. WDYT?

> The existing regression tests (HIVE-12586) based on TPC-DS have certain
> shortcomings:
> The table statistics do not reflect cardinalities from a specific TPC-DS
> scale factor (SF). Some tables are from a 30TB dataset, others from 200GB
> dataset, and others from a 3GB dataset. This mix leads to plans that may
> never appear when using an actual TPC-DS dataset.
> The existing statistics do not contain information about partitions something
> that can have a big impact on the resulting plans.
> The existing regression tests rely on more or less on the default
> configuration (hive-site.xml). In real-life scenarios though some of the
> configurations differ and may impact the choices of the optimizer.
> This issue aims to address the above shortcomings by using a curated
> TPCDS30TB metastore dump along with some custom hive configurations.
