Overview
Date._strptime
method.Date._strptime
in Java on Java timestamp parser and RubyDateParser embulk/embulk#608Details
My application, Embulk, is using JRuby and heavily using
Date._strptime
method internally to parse timestamp strings. I found that the heavy usage is one of the performance bottlenecks in my application.To mitigate the performance issue, I started implementing
Date._strptime
in Java. The features are:Date._strptime
in CRubyorg.jruby.util.RubyDateFormatter
andorg.jruby.lexer.StrftimeLexer
