PragmaTwice opened a new pull request, #3155: URL: https://github.com/apache/kvrocks/pull/3155
Accessing undeclared keys may lead to unexpected behavior in both Kvrocks and Redis. Specifically in Kvrocks, undeclared keys will not be protected by key locks, which may face atomic issues of rocksdb IO. If `lua-strict-key-accessing` is enabled, we can garantee that there is no write on undeclared keys, so EVAL & FCALL in multiple threads should be safe. But for disabled `lua-strict-key-accessing`, it is quite dangerous if users use undeclared keys in scripting. So we add `exclusive` flag to EVAL, EVALSHA and FCALL commands in such case. NOTE that *_RO commands are not affected. -- This is an automated message from the Apache Git Service.
