Subject: cqlsh --request-timeout=3600 doesn't seems to work


i'm running count query for a very small table (less than 1000 000 records).
When the amount of records gets to 800 000 i receive read timeout
error in cqlsh.
I tried to run cqlsh with option --request-timeout=3600, but receive same error,
what should I do in order not to recieve timeout exception?
