--------------------------------
Summary: Add separate option for topic regex pattern matching in
tools
Key: KAFKA-19887
URL: https://issues.apache.org/jira/browse/KAFKA-19887
Project: Kafka
Issue Type: Improvement
Reporter: Lan Ding
Assignee: Lan Ding
see [https://github.com/apache/kafka/pull/20865#discussion_r2522364991]
Currently, the {{--topic}} option in kafka-topics.sh serves dual purposes - it
accepts both literal topic names and regex patterns, which causes ambiguity and
usability issues. This is particularly problematic for topic names containing
dots (.) and other regex metacharacters.
*Implementation Plan:*
# 4.x: Introduce the new regex option and deprecate regex usage in {{--topic}}
# 5.x: Remove regex functionality from {{--topic}} option entirely
This improvement could also be extended to all other scripts that support regex
patterns for consistency.
