cassandra upgrade from 0.6 to 0.7.2 -

-

i followed instructions in news.txt upgrade cassandra 0.6 0.7.2. instructions are: process upgrade is: 1) run "nodetool drain" on each 0.6 node. when drain finishes (log message "node drained" appears), stop process. 2) convert storage-conf.xml new cassandra.yaml using "bin/config-converter". 3) rename of keyspace or column family names not adhere '^\w+' regex convention. 4) start cluster 0.7 version. 5) initialize keyspace , columnfamily definitions using "bin/schematool import". you need 1 node.

i did first 3 steps. drain node, stop cassandra 0.6, convert old storage-conf.xml cassandra.yaml. start cassandra 0.7.2 using: "bin/cassandra -f". complains following errors. wondering whether followed right instructions. if so, how fix problem?

"fatal configuration error org.apache.cassandra.config.configurationexception: saved_caches_directory missing"

default location saved_caches_directory /var/lib/cassandra/saved_caches (from wiki). try create manually (dont forget user permissions)

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.
