请求提供rpk topic create命令的主题配置规范参考文档及选项获取指引

Hey there! I totally get the frustration of trying to track down the full list of topic config options for Redpanda when using rpk topic create with the -c/--topic-config flag— it’s annoying that the docs don’t link directly to that list. Let me share a few solid ways to get this info, right from your setup or official resources:

• Pull the list directly via rpk (most reliable):
  Redpanda’s own rpk tool has a built-in command to list every supported topic-level configuration, complete with default values, data types, and descriptions. Just run this in your terminal:

  rpk topic config list
  

  This is the most up-to-date source because it pulls directly from your Redpanda cluster’s current version, so you’ll see exactly what’s available for your setup.

• Use Kafka compatibility + Redpanda-specific docs:
  Redpanda is fully Kafka API-compatible, so almost all standard Kafka topic configurations work seamlessly with it. For Redpanda-exclusive tweaks (like tiered storage or partition auto-balancing settings), head to the official Redpanda docs and search for "Topic Configuration"— you’ll find a dedicated section that breaks down both standard and Redpanda-specific options. Key Redpanda-only configs to look out for include redpanda.remote.write (for tiered storage) and redpanda.partition_autobalance_mode (for automated partition balancing).

• Use Kafka’s kafka-configs tool (if you have it):
  Since Redpanda supports Kafka’s admin APIs, you can use the kafka-configs.sh utility (from a standard Kafka distribution) to inspect configs for an existing topic. Run this command (swap in your broker address and topic name):

  kafka-configs.sh --bootstrap-server <your-redpanda-broker>:9092 --entity-type topics --describe --entity-name <your-topic-name>
  

  This will show you all applied and default configs for the topic, including both standard Kafka and Redpanda-specific ones.
