----------------------------------------
Summary: Remove Deadline#timeLeft()
Key: FLINK-15740
URL: https://issues.apache.org/jira/browse/FLINK-15740
Project: Flink
Issue Type: Improvement
Components: API / DataStream, Tests
Reporter: Chesnay Schepler
Fix For: 1.11.0
As shown in FLINK-13662, {{Deadline#timeLeft()}} is conceptually broken since
there is no reliable way to call said method while ensuring that
a) the value is non-negative (desired since most time-based APIs reject
negative values)
b) the value sign (+,-) corresponds to preceding calls to {{#hasTimeLeft()}}
As a result any usage of the following form is unreliable and obfuscating error
messages.
{code:java}
while (deadline.hasTimeLeft()) {
doSomething(deadline.timeLeft());
} {code}
All existing usage should be migrate to either
{code:java}
while (deadline.hasTimeLeft()) {
doSomething();
} {code}
or
{code:java}
while (true) {
doSomething(deadline.timeLeftIfAny());
}
{code}
