Redis performance: hIncrByFloat function or custom Lua script ？

let's say I have hash data stored in redis:

{"fee":0.11,"name":"scott"}

now I want to add some value to the field 'fee', should I use the hIncrByFloat command or , write a Lua script to implement that? please advice from the performance view, thanks!

Use HINCRBYFLOAT.

Core commands are more performant than Lua scripts in (probably) every scenario. Use Lua to compose flows that consist of core commands and server-side logic, but not to replace a single core command.

You can, and should, test performance yourself - redis-benchmark can be used for that.
