             Summary: Use durationType instead of stringType for time related config options
                 Key: FLINK-26007
                 URL: https://issues.apache.org/jira/browse/FLINK-26007
             Project: Flink
          Issue Type: Improvement
            Reporter: Marios Trivyzas


Check and change all relevant config options so that we have a well typed/defined type instead of parsing a string.

*NOTE:* This is a breaking change!

 

e.g.: 
{noformat}
AkkaOptions#WATCH_HEARTBEAT_PAUSE

public static final ConfigOption<String> WATCH_HEARTBEAT_PAUSE =
    ConfigOptions.key("akka.watch.heartbeat.pause")
            .defaultValue("60 s")
            .withDescription(
                    Description.builder()
                            .text(
                                    "Acceptable heartbeat pause for Akka’s DeathWatch mechanism. A low value does not allow an"
                                            + " irregular heartbeat. If TaskManagers are wrongly marked dead because of lost or delayed"
                                            + " heartbeat messages, then you should increase this value or decrease akka.watch.heartbeat.interval."
                                            + " Higher value increases the time to detect a dead TaskManager. A thorough description of Akka’s"
                                            + " DeathWatch can be found %s",
                                    link(
                                            "http://doc.akka.io/docs/akka/snapshot/scala/remoting.html#failure-detector",
                                            "here"))
                            .build());{noformat}
