The .Q namespace tools | Reference | kdb+ and q documentation - Kdb+ and q documentation (kx.com)

based on this, it seems .q.en reads the sym file from disk every time it is called, which would pick up any updates that are coming from other processes.

However, I am not 100% certain and I am not proficient in reading the k implementation to know whether or not this is the case. I’m hoping someone has done this exercise and can answer it for me.

Hi - yes it does. The corresponding logic block in .Q.en is

 

(/:d,s)??,/?:'{$[0h=@x;,/x;x]}'t c // which translates to :path/to/sym ? distinct raze distinct each (symlist from each column)
