-----------------------------------
Summary: Enhance time unit features
Key: NIFI-5854
URL: https://issues.apache.org/jira/browse/NIFI-5854
Project: Apache NiFi
Issue Type: Improvement
Components: Core Framework
Affects Versions: 1.8.0
Reporter: Andy LoPresto
Assignee: Andy LoPresto
There is some ambiguity with time units (specifically around processor
properties). Two features which I think should be added:
* Currently only whole numbers are parsed correctly. For example, {{10
milliseconds}} and {{0.010 seconds}} are functionally equivalent, but only the
former will be parsed. This is due to the regex used in
{{StandardValidators.TIME_PERIOD_VALIDATOR}} which relies on
{{FormatUtils.TIME_DURATION_REGEX}} (see below). Decimal amounts should be
parsed
* The enumerated time units are *nanoseconds, milliseconds, seconds, minutes,
hours, days, weeks*. While I don't intend to extend this to "millennia", etc.
as every unit including and above *months* would be ambiguous, *microseconds*
seems like a valid and missing unit
*Definition of {{FormatUtils.TIME_DURATION_REGEX}}:*
{code}
public static final String TIME_DURATION_REGEX = "(\\d+)\\s*(" +
VALID_TIME_UNITS + ")";
public static final Pattern TIME_DURATION_PATTERN =
Pattern.compile(TIME_DURATION_REGEX);
{code}
