Kafka 0.11.0.0 (Confluent 3.3.0) added support to manipulate offsets for a consumer group via cli kafka-consumer-groups
command.
kafka-consumer-groups --bootstrap-server <kafkahost:port> --group <group_id> --describe
Note the values under "CURRENT-OFFSET" and "LOG-END-OFFSET". "CURRENT-OFFSET" is the offset where this consumer group is currently at in each of the partitions.

First of all, please note that token expiration and revoking are two different things.
A JWT token that never expires is dangerous if the token is stolen then someone can always access the user's data.

There are certain files created by particular editors, IDEs, operating systems, etc., that do not belong in a repository. But adding system-specific files to the repo's .gitignore
is considered a poor practice. This file should only exclude files and directories that are a part of the package that should not be versioned (such as the node_modules
directory) as well as files that are generated (and regenerated) as artifacts of a build process.
All other files should be in your own global gitignore file:
.gitignore
in your home directory and add any filepath patterns you want to ignore.Note: The specific name and path you choose aren't important as long as you configure git to find it, as shown below. You could substitute
.config/git/ignore
for.gitignore
in your home directory, if you prefer.
