> Row-level operations such as UPDATE, DELETE, MERGE are becoming more and more 
> important for modern Big Data workflows. Use cases include but are not 
> limited to deleting a set of records for regulatory compliance, updating a 
> set of records to fix an issue in the ingestion pipeline, applying changes in 
> a transaction log to a fact table. Row-level operations allow users to easily 
> express their use cases that would otherwise require much more SQL. Common 
> patterns for updating partitions are to read, union, and overwrite or read, 
> diff, and append. Using commands like MERGE, these operations are easier to 
> express and can be more efficient to run.
> Hive supports [MERGE|https://blog.cloudera.com/update-hive-tables-easy-way/] 
> and Spark should implement similar support.
