How to use Q convert KDB+ data into binary?

Hi All,

Suppose:
Header message:

records types byte

1000     11   368

My question:

How I should be in accordance with the specific byte aligned (8 bytes or others), convert KDB + data into binary?

Have a good week!

Thanks,

Sky

t:( records:1000;types 11; byte:368)

save `:t

This will save your table to binary

Hi Jeremy,

This method can’t set up 8 byte alignment.


If according to this method, the header file, structure and byte alignment is what?


Thanks,

Sky

While you can try to shoehorn q to write some binary output of the format you want, it’s far from perfect – q does not have built-in support for non-q binary output.

I guess a better bet is to write a simple library (dll/so) yourself that performs the binary output instead.
