> HIVE-7100 introduced a way to skip the trash directory, when deleting
> table-data, while dropping tables.
> In HIVE-9083/HIVE-9086, I extended this to work when partitions are dropped.
> Here, I propose a table-parameter ({{"auto.purge"}}) to set up tables to
> skip-trash when table/partition data is deleted, without needing to say
> "PURGE" on the Hive CLI. Apropos, on {{dropTable()}} and {{dropPartition()}},
> table data is deleted directly (and not moved to trash) if the following hold
> true:
> # The table is MANAGED.
> # The {{deleteData}} parameter to the {{HMSC.drop*()}} methods is true.
> # Either PURGE is explicitly specified on the command-line (or rather,
> {{"ifPurge"}} is set in the environment context, OR
> # TBLPROPERTIES contains {{"auto.purge"="true"}}
