this PR
1. refactor physical properties, property deriver and property regular
to ensure Nereids could generate plan with sufficent PhysicalDistribute.
2. refactor PhyscialPlanTranslator to ensure all ExchangeNode generated
by PhysicalDistribute, except CTEConsumer. We will refactor all cte
related node later.
the detail changes of this PR:
1. update DistributionSpec of physical properties:
- Any: random distribution, used in output and require
- StorageAny: random distribution but constrained by where the data is stored, used in output
- ExecutionAny: random distribution to present random shuffle, used in output
- Gather: gather distribution, used in output and require
- StorageGather: gather distribution but constrained by where the data is stored, used in output
- Replicated: broadcast distribution
- Hash: bucket distribution
2. update shuffle type of DistributionSpecHash
- REQUIRE: used in require
- NATURAL: distribution as storage engine hash algorithm, constrained by where the data is stored
- STORAGE_BUCKETED: distribution as storage engine hash algorithm
- EXECUTION_BUCKETED: distribution as execution engine hash algorithm
3. update HideOneRowRelationUnderSetOperation to MergeOneRowRelationIntoSetOperation
4. update property deriver of SetOperation to ensure suitable PhysicalDistribute be added
at top and below of SetOperation
5. refactor PhysicalPlanTranslator to ensure no unplanned exchange node will be added
