« I’ve setup many views based on a single large table. How much of a performance penalty will I pay? | Main | How do I efficiently retrieve the first n rows of a query result? »

I want to keep kdb rdb super fast and prevent users from introducing large latencies by using a timeout argument of 2 seconds. is this a good idea?

It is true that no single user query will block for more than the time specified in the -T command line argument. However, be sure to disable timeout via \T 0 prior to executing the end-of-day batch processing, or it will fail with a 'stop error.
