For partitioned topics, it's often useful to reset the group position all partitions to a specific time rather than a specific offset. This PR teaches
kt group -reset
to accept a time string (as parsed by https://github.com/markusmobius/go-dateparser) in addition to the special values newest and oldest. For example,kt group -group some-group -topic some topic -reset "6 hours ago"
is much more convenient than trying to figure out which offsets correspond to that time and invokingkt group -reset
for each of N partitions.Also,
kt group -reset ARG
prints the resulting offsets and lags when ARG is "newest", "oldest" or a time string, rather than omitting them on the assumption that the lag is unknown. As far as I can tell the value ofspecialOffset
is unrelated to whether the offset was previously stored on the broker or not.
