Motivation

https://redis.io/docs/latest/develop/interact/programmability/lua-api/#script_flags https://redis.io/docs/latest/develop/interact/programmability/eval-intro/#eval-flags https://redis.io/docs/latest/develop/interact/programmability/functions-intro/#function-flags

It seems that only the name flag of redis function is supported now, and we can support the parsing of some other flags. For example no-writes, allow-cross-slot-keys, etc.

On the one hand, there are already existing requirements issue: https://github.com/apache/kvrocks/issues/1884 , https://github.com/apache/kvrocks/issues/2133

On the other hand, for the optimization function of Lua script in the future, we may need to support some special flags like dragonflydb to enable optimization. Relevant information:

Solution

I'm thinking about how to implement it. Generally speaking, the process of parsing and obtaining flag should be more general.
