795-796: The implementation ofDoThroughDB()andDoUpdateCache()methods inPKSetexAtCmdlooks good, ensuring that the command interacts properly with both the database and the cache.src/pika_kv.cc (1)
1707-1709: The implementation ofDoThroughDB()correctly delegates toDo(), aligning with typical command handling in Redis-like systems.src/pika_command.cc (1)
373-373: The addition ofkCmdFlagsDoThroughDBandkCmdFlagsUpdateCacheto thePKSetexAtCmdcommand flags is aligned with the PR objective to ensure the command updates the cache. This is a crucial change for maintaining consistency between the cache and the database state.Verification successful
The
DoUpdateCachemethod inPKSetexAtCmdhas been implemented to update the cache with the key, value, and expiration time. This confirms that the new flagskCmdFlagsDoThroughDBandkCmdFlagsUpdateCacheare appropriately integrated to ensure the command updates the cache.

Ensure proper error handling for non-positive expiration times in DoUpdateCache().
- // TODO(): handle error
+ if (expire <= 0) {
+ // Handle the case where the expiration time has already passed
+ return; // Consider logging this event or handling it according to business requirements

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
