Topic Selection

The Topic Selection step determines which topics from the source cluster will be replicated to the destination. The suite scans the source cluster and displays all discovered topics with their compatibility status.

Topic Overview

A top panel summarizes the topic landscape:

Metric	Description
Compatible Topics	Topics that can be replicated without issues.
Conflicting Topics	Topics that have configuration conflicts with the destination cluster (for example, partition count mismatches or naming collisions).

Each topic row displays:

• Name: The full topic name on the source cluster.
• Partitions: The number of partitions configured for the topic.
• Compatible: A status indicator showing whether the topic can be replicated cleanly.

Selection Methods

Manual Selection

Use the checkboxes next to each topic to select individual topics for replication. This approach is best when migrating a small, known set of topics.

Pattern Matching

Enter wildcard patterns to select topics by name. For example:

Pattern	Result
test-*	Selects all topics whose names start with “test-”.
*-orders	Selects all topics whose names end with “-orders”.
prod-*-events	Selects topics matching the prefix “prod-” and suffix “-events”.

Exclusion Patterns

Define patterns to exclude specific topics from selection. For example:

Pattern	Result
*-internal	Excludes all topics whose names end with “-internal”.
__*	Excludes topics with the double-underscore prefix (typically internal Kafka topics).

Selection Summary

The Selection Summary panel updates in real time as you modify your selections:

Field	Description
Topics Selected	The count of topics currently selected for replication.
Total Partitions	The aggregate partition count across all selected topics.
Compatibility Status	An overall status indicating whether all selected topics are compatible.

Additional Controls

• Search: Filter the topic list by name using the search bar.
• Visible Filter: Toggle between showing all topics or only selected topics.
• Clear: Reset all selections.
• Pagination: Navigate through large topic lists using page controls.

Tip

Use a combination of pattern matching and exclusion patterns to quickly select large groups of topics while filtering out internal or test topics.
