public class IntervalParserUtils
extends Object

Copy of `org/apache/spark/sql/catalyst/util/SparkIntervalUtils.scala` from Apache Spark. Delta table properties store the interval format. We need a parser in order to parse these values in Kernel.

Method Detail

safeParseIntervalAsMillis

public static long safeParseIntervalAsMillis(String input)

Parse the given interval string into milliseconds. For configs accepting an interval, we require the user specified string must obey:

• Doesn't use months or years, since an internal like this is not deterministic.
• Doesn't use microseconds or nanoseconds part as it too granular to use.

Returns:

parsed interval as milliseconds.
