nosql - Graph DB's Vs Azure Table storage for a Social networking application -

-

i'm starting on architecture work .net based social networking application hosted on azure cloud. going using asp.net mvc on front end.

i consider options storage. considering scalability needs , due inter-connected nature of application, sql azure has been ruled out.

what main considerations in choosing graph db such sones graphdb or neo4j have features specific social networking application against using windows azure table storage achieve needs.

i'm concerned development time, cost, ability leverage existing skills .net , reliability of graph db platforms , ease of setup , administration.

graph databases designed applications such social networks. ease of development, may best start graphdb. key advantage on key-value database powerful query , traversal capabilities. easy to, instance, find occurrences of friends of friends using graphdb query syntax.

the benefit of key-value database service azure table low cost, minimal administrative overhead , scalability. can store 500tb of data per azure storage account , setup accounts in multiple regions. there no server setup or database administration overhead , visual studio sdk easy use. down side graph query support not built in , must index off primary key / row key pair. additional azure table design pattern please see https://azure.microsoft.com/en-us/documentation/articles/storage-table-design-guide/

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.
