i have been doing reading on topic not able find right information, have been using services twitter streaming, datasift , other data push service. wanted understand how following services work, the number of tweets received per second high. a number of people connect specify keywords want receive tweets for, these can complex boolean queries. realtime checking of tweets against these boolean queries , streaming data right connection. any pointer towards kind of architecture being used helpful. i think first need understand magnitude , resources of services twitter trying create understanding of!! performance can handled managing taking care of both below mentioned fronts. imagine multi-tiered eco-system load balancers, multiple web-servers , large data centres distributed caching!! irrespective of complexity of algorithm performance can managed making algorithms multi-threaded!! if want understand try reading map-reduce, hadoop etc idea

while programming, many times i've come across following design choice: user creates object , passes other object processes in way in second stage. as example, imagine raytracer. user creates sphere properties , calls raytracer.addtraceable(sphere) . now, there 3 ways can think of doing this. the raytracer becomes responsible of deallocating memory allocated sphere object the user needs deallocate memory allocated sphere object. the raytracer copies sphere object , both user , raytracer deallocate local copy. generally best design choice in such case? there other options besides ones mentioned (not including smart pointers)? ps: i've come across same problem in plain c when using object oriented approach. the consistent use of raii makes moot point. using smart pointer such std::shared_ptr object owned all of pointers , deleted after last pointer destroyed. c doesn't have convenient way express raii idiom.

in erlang can use define macro or .hrl file keep configuration @ 1 place. whats best place in elixir. i couldn't find elegant way of doing it. right doing like:- def get_server_name "test" end am missing something? whether use functions or macros should matter in end, if you're looking "keeping in 1 place" part, i'd suggest putting in own namespace/module defmodule myapp.configuration def server_name "foo" end # or if prefer having on 1 line def host_name, do: "example.com" # complete equivalency, can use macro defmacro other_config "some value" end end and in app, instead of including file, can alias module have short prefix indicate it's configuration, , indicate come elsewhere defmodule myapp.server alias myapp.configuration, as: c end or if want use names directly defmodule myapp.server import myapp.configuration end

i have 2 member replica set (within sharded cluster), no arbiter. know recommended design have 3 servers (or odd number) right have stick design. the problem when primary down, secondary doesn't elected temporary master (since priority both servers 1 , have no arbiter). is there way automatic failover (slave becomes primary -> primary online -> default primary gets previous state)? thank you! you must have @ least 3 members in replicaset, having 2 members worse having single node (never ever this!!). problem worst think, main problem if secondary goes down, primary demote secondary , go down because have no more primary. don't know why 'have stick configuration', can not solution. the solution create , arbiter , node, lightweight member of replicaset has no actual data , there take part in election new primary if 1 of other members goes down.
