c# - ADO.net SqlTransaction improves performance -

-

i'm doing work involves inserting batch of records sql database. size of batch vary arguments sake can 5000 records every 5 secs. less though. multiple processes writing table, nothing reading it.

what have noticed during quick test using sqltransaction around whole batch insert seems improve performance.

e.g. 

sqltransaction trans = connection.begintransaction() mystoredproc.transaction = trans; sampledata.foreach(executenonqueryagainstdb); transaction.commit();

i'm not interested in having ability rollback changes wouldn't have considered using transaction except seems improve performance. if remove transaction code inserts go taking 300ms around 800ms!

what logic this? because understanding transaction still writes data db locks records until committed. have expected have overhead...

what looking fastest way insert.

if looking fast wqay insert/load data have @ sqlbulkcopy class

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.
