> 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
> Priority: Major
> Labels: pull-request-available
>
> 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

> |<----- 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
