node.js - RabbitMQ multi server instances - only one active consumer -


i have node.js server, rabbitmq consumer. want scale app multiple instances, keep consumer active. how can that?

thanks

you should able state want exclusive access queue when start consuming. information available here means first consumer exclusive access, other attempt after rejected.

extract of relevant information provided link below:

consume(short reserved-1, queue-name queue, consumer-tag consumer-tag, no-local no-local, no-ack no-ack, bit exclusive, no-wait no-wait, table arguments) ➔ consume-ok

and exclusive bit information

bit exclusive

request exclusive consumer access, meaning consumer can access queue.

the client may not gain exclusive access queue has active consumers. error code: access-refused

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
