Overview
A detailed inspection operation that retrieves partition layout, replica assignments, and configuration for specified topics.
Description
Topic Description provides comprehensive metadata about one or more topics including partition count, leader for each partition, replica list, in-sync replica (ISR) list, and topic-level configuration. It can filter results to show only under-replicated, unavailable, or under-min-ISR partitions for operational diagnostics.
Usage
Use this principle for operational monitoring, troubleshooting partition imbalances, verifying replica placement, and inspecting topic configuration.
Theoretical Basis
- Metadata Retrieval: Query partition metadata via DescribeTopicPartitions or MetadataRequest.
- Config Retrieval: Separately fetch topic configuration via DescribeConfigs.
- Filtering: Apply optional filters for under-replicated, unavailable, or under-min-ISR partitions.
- Display: Present partition information with leader, replicas, and ISR for each partition.
