which one is the best for mysql connection? -


here question below.

case 1:

always make connection or disconnection every tcp client.

case 2:

only make 1 connection , share connection every tcp client.

which 1 best performance? thanks!

i assume architecture n-tier, like:
db_server <---> application <----> many_clients
...and consider solution in application part?
assuming so, still depends:

  1. from performance point of view better have fewer connections. gain of squeezing multiple client requests single connection may small if network has low latency between db_server , application.
  2. the logic of application ensure single (multiplexed) connection can simple, if every client requires 1 query. may complex if communication clients requires doing many sql queries, , if intervene. cost (in terms of aplication complexity) may out-weight small benefits in network performance.

so have consider gain , cost... result depends heavily on both above factors.

of course, can hit connection-table size limit if consider many concurrent connections. or may have securitiy-specific connection limitation between db_server , application. in such cases multiplexing client connection 1 may option.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
