q lang - Is there a way to replay a gzip-compressed log file in kdb+ without uncompressing it first? -


streaming execute, -11!, not work on named pipes, obvious solution of redirecting gzip -cd output named pipe , passing -11! not work.

-11! accepts compressed file , streams long compressed -19! (using 2 compression algorithm parameter, gzip).

the difference between normal gzipped file , kdb compressed 1 few bytes @ beginning of file.

edit (see comment) thanks, isn't true - bytes different @ end of file

so possible solution prepend gzipped files (if weren't produced -19!) appropriate byte array first.

(side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now...
