TruncDatePartitionExpr

case class TruncDatePartitionExpr(partitionColumn: String, format: String) extends OptimizablePartitionExpression with Product with Serializable

The rules for generation expression that use the function trunc(col, format) such as trunc(timestamp, 'year'), trunc(date, 'week') and trunc(timestampStr, 'hour')

partitionColumn

partition column using trunc function in the generation expression

format

the format that specifies the unit of truncation applied to the partitionColumn
