Walkthrough

This pull request modifies the PikaClientConn::IsInterceptedByRTC method to enhance command interception logic based on command types and associated flags. It introduces a generalized approach by retrieving a command object using g_pika_cmd_table_manager->GetCmd(opt) and checking if the command requires cache reading through IsNeedReadCache(). The evaluation of various flags against cache configurations in g_pika_conf allows for broader command handling. Additionally, comments in the ReadCmdInCache method were updated to reflect these changes. There are no alterations to exported or public entities.

Changes

File(s)	Change Summary
src/...pika_client_conn.cc	Modified IsInterceptedByRTC to use a generalized command lookup and cache requirement check (via IsNeedReadCache() and flag evaluations). Updated comments in ReadCmdInCache to reflect the broader command handling logic.

Poem

I’m a little rabbit, hopping through code,
Inspecting commands on our caching road.
With flags that guide and logic anew,
Our PikaClientConn now knows what to do!
🐇💻 Happy hops in every review!

  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

这个改动不一定合理，我看了前面的相关pr，有提到rtc最好是拦截单key。同时如果是但是哪怕纯内存也比较慢的操作不能走rtc。

This change is not necessarily reasonable. I looked at the previous related PR and mentioned that RTC is best to intercept single keys. At the same time, if it is, even if it is pure memory, it is relatively slow, it cannot use rtc.

可以把当前 RedisCache 开启的命令都加回来，我们这边目前已经解决了缓存和数据库数据一致性的问题

You can add all the commands currently enabled in RedisCache. We have solved the problem of cache and database data consistency.

Rtc不可能支持redis的所有命令吧，这样会导致上层网络框架堵塞的

Rtc cannot support all commands of redis, as this will cause the upper-level network framework to be blocked.
