Project: Spark
Issue Type: New Feature
Components: Spark Core, SQL
Affects Versions: 3.3.0
Reporter: gabrywu
Hi, folks,
In Hive, we can use following command to merge small files, however, there is
not a corresponding command to do that.
I believe it's useful and it's not enough only using AQE. Is anyone working on
this to merge small files? If not, I want to create a PR to implement it
{code:java}
ALTER TABLE table_name [PARTITION (partition_key = 'partition_value' [, ...])]
CONCATENATE;{code}
