-------------------------------

             Summary: Skip the latest N partitions when creating ClusteringPlan
                 Key: HUDI-2194
                 URL: https://issues.apache.org/jira/browse/HUDI-2194
             Project: Apache Hudi
          Issue Type: Task
            Reporter: Yue Zhang


As we known, SparkRecentDaysClusteringPlanStrategy is the default clustering 
strategy to create ClusteringPlan. And it is useful when Hudi table is 
partitioned by time.

 

For now, users can set 
`hoodie.clustering.plan.strategy.daybased.lookback.partitions` to  control the 
number of partitions to list from the latest partition to create ClusteringPlan.

For example, we have 6 partitions based on date, and users set 
`hoodie.clustering.plan.strategy.daybased.lookback.partitions` 2

20210718 | 20210719 | 20210720 | 20210721 | 20210722 | 20210723(latest) |

                                                                              
|<----- choose to cluster ---->|

Sometimes users also what to skip x partitions from latest when make clustering 
plan because latest partitions contains lots of update data or some reasons 
else.

 

This patch will add a new config named `

hoodie.clustering.plan.strategy.daybased.skipfromlatest.partitions

` to set the 

number of partitions to skip from latest when choosing partitions to create 
ClusteringPlan

 

for example users set 
`hoodie.clustering.plan.strategy.daybased.lookback.partitions` 2 and 

`

hoodie.clustering.plan.strategy.daybased.skipfromlatest.partitions

` 2

| 20210718 | 20210719 | 20210720 | 20210721 | 20210722 | 20210723(latest) |

                                        |<-----  choose  ----->|
