performance - Session optimization in Jetty + Wicket -

-

is there way swap sessions onto disk jetty if idle n.n. minutes?

it under investigation, suspect have many idle users logged in large session size. so, while doing nothing, session pushed onto disk.

is there setting or utility or way achieve this? 

we using wicket+jetty.

simply shortening session destroy timeout not option.

assuming you're running jetty 7, answer yes.

because it's possible configure & run jetty in multiple ways, it's pretty hard give definitive answer how turn on in scenario.

the outcome want call "setidlesaveperiod" on "hashsessionmanager" non-zero value (the number of seconds session should idle before pushed disk)

if you're running server default jetty.xml you'll need add (untested):

<configure class="org.mortbay.jetty.webapp.webappcontext">   .   .   .   <set name="sessionhandler">     <new class="org.mortbay.jetty.servlet.sessionhandler">       <arg>         <new class="org.mortbay.jetty.servlet.hashsessionmanager">           <set name="storedirectory">your/chosen/directory/goes/here</set>           <set name="idlesaveperiod">300</set>         </new>       </arg>     </new>   </set>   .   .   . </configure>

c# - Is it possible to remove an existing registration from Autofac container builder? -

-
something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
