> Support microseconds in RegexDateTimeMatcher
> --------------------------------------------
>
> Key: NIFI-12426
> URL: https://issues.apache.org/jira/browse/NIFI-12426
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Extensions
> Reporter: Matt Burgess
> Priority: Major
> Fix For: 1.25.0, 2.0.0
>
>
> If a timestamp in the input has microseconds and a RecordReader is using
> Infer Schema, the data type will be inferred as a string rather than a
> timestamp regardless of the Timestamp Format property in the reader. Although
> SimpleDateFormat doesn't support microseconds, it is forgiving in the parsing
> of a timestamp string and accepts ".SSSSSS" as a milliseconds format even
> though the microseconds will not be honored.
> However when inferring the schema, the input must also pass the
> RegexDateTimeMatcher which checks that it "looks like" a timestamp and within
> the legitimate length boundaries. This matcher enforces a 3-digit length of
> milliseconds and will fail to match input with microseconds. This matcher
> should accept 6 digits of fractional seconds and allow the other matchers to
> proceed.
