Size of a table (in bytes) in Q

How can I read the size of a table (in bytes) in Q?

I know that hcount returns the size of a file in bytes, but I can't find something similar for tables (or in general any object...)

Solution

  • this is serialized (wire) object size
    play around with \w this will give you object size in memory

    q)a:til 10000
q)count -8!a
40014
q)\w
176464 67108864 67108864 0 0 2137387008j
q)b:til 10000
