what's meaning of the "true/false" from "groupy...select"?THANKS

[Appleyuchi]

The complete code is:

https://paste.ubuntu.com/p/hpWB87kT6P/

The result is:

2> (true,1,diaper,4)

7> (true,3,rubber,2)

4> (true,1,beer,3)

7> (false,3,rubber,2)

7> (true,3,rubber,8)

That's the meaning of  true/false in the result 

after running the above code?

Thanks for your help~!

The "true" means the message is an insert/update after, the "false" means the message is a retraction (for the old record that needs to be modified).
