object TemporalQueryUtil extends Serializable with Logging

Temporal query utils for interval axis of type Timestamp

Usage: import ch.zzeekk.spark.temporalquery.TemporalQueryUtil._ // this imports temporal* implicit functions on DataFrame and Columns implicit val tqc = TemporalQueryConfig() // configure options for temporal query operations implicit val sss = ss // make SparkSession implicitly available val df_joined = df1.temporalJoin(df2) // use temporal query functions with Spark
