> PR #7969 added {{HadoopFsRelation.refresh()}} calls in {{DataSourceStrategy}} to make
test case {{InsertSuite.save directly to the path of a JSON table}} pass. However, this forces
every {{HadoopFsRelation}} table scan to do a refreshing, which can be super expensive for
tables with large number of partitions.
