postgresql - Multiple connection pool on same PostgresSql -

-

my application has 2 sections mainly,

  1. user interface written in angular uses django python end.
  2. heavy map reduce kind of process.

both uses postgres up, doubt if use same connection pool both, @ time when map reduce runnning due heavy lookup other application won't work because of no connection available. there work around this.(avoiding postgres in backlog)

ps: using pgbouncer pooling

simplest approach separating 2 sections. @ least respect connection resources. (whether e.g. memory consumption , gc benefit restructuring not asked for)

you may achieve using 1 of following approaches:

  1. use 2 separate pools, 1 each section.
    way, may setup pools according connection requirements per section.

  2. change code maintain sufficient "free" resources other section.
    quite tedious , useful resource requirements need fine grain control depending on internal state of algorithms.

usually you'd want go suggestion 1.

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.

erlang - Saving a digraph to mnesia is hindered because of its side-effects -

-
updated the digraph library in erlang implements data type side-effectful. each operation on data type saves new state in ets table -- instead of returning altered version of itself, more common in functional languages. the problem usage perspective, impedes effort store or pass around state in convenient way requiring me first "collect" state before can start juggle around. the closest solution have seen far serializer/deserializer , these have drawback tied current structure of digraphs instead of operating on abstract type -- prevents future proof solution. update pascal pointed out serializer utilizes interface of digraph, , hence eliminates drawback mentioned above. better, albeit still inconvenient, see no better alternative. what recommendation on how store digraphs? should go different data type altogether? thanks. i not sure understand concern. fact digraph stored in ets transparent in user interface, might want chnge either exchange digr...
