…rceDistribution) which later causes an error during EnforceSort (without our patch). The next DataFusion version 46 upgrade does the proper fix, which is to not insert the coalesce in the first place. test: recreating the iox plan: * demonstrate the insertion of coalesce after the use of column estimates, and the removal of the test scenario's forcing of rr repartitioning test: reproducer of SanityCheck failure after EnforceSorting removes the coalesce added in the EnforceDistribution fix: special case to not remove the needed coalesce

Ok, the MSRV is failing. We don't care about that one for our fork. |

Patches
Patches map to commits 1:1 (i.e. every patch is exactly 1 commit) and are ordered for easier correlation of the description and the respective commits. They are also grouped in 3 stages.
A: Dummy
No actual patches, can be dropped at any point:
B: CI Fixes
Need to get CI up and running before picking any actual patches:
can be dropped when we upgrade to DF version 47
All commits afterwards should build cleanly!
C: Patches
These are the actual relevant patches:
chore: default=true for skip_physical_aggregate_schema_check, and add warn logging:until we chase down all warnings in our iox logs (see https://github.com/influxdata/influxdb_iox/issues/12404 )
(New) Test + workaround for SanityCheck plan:according to this slack thread, we can drop this with DataFusion version 49.
chore: skip order calculation / exponential planning:workaround for Exponential planning time (100s of seconds) with
UNIONandORDER BYqueries apache/datafusion#13748 -- which should be fixed in DataFusion version 49fix: temporary fix to handle incorrect coalesce (inserted during EnforceDistribution) which later causes an error during EnforceSort (without our patch). The next DataFusion version 46 upgrade does the proper fix, which is to not insert the coalesce in the first place.:There is EAR-5822 (also see https://github.com/influxdata/influxdb_iox/issues/13310 ) despite what the note in Patched DataFusion version
45.0.0#54 and ParallelizeSorts, a subrule of EnforceSorting optimizer, should not remove necessary coalesce. apache/datafusion#14691 (comment) say, this is still required for DF version 46. Otherwise the regression test fails. Also see this slack thread.
