architecture - Using Memcache for Centralization of Distributed Cache Against DB -

-

I'm new to remembering and thinking whether the following ideas work or exist with successful cases or just Going to the bin? Save me and any guidance is highly appreciated. It goes here ...

Currently 1 MySQL DB is using memmache using additional memory to feed the already hungry webserver, which works in the frontend. Now we are going to start a new DB and webserver again and have not forgotten a son hungry to eat, we are considering alternate ways to do mashchach so that more DB and webserver should be connected in the future quickly. Could:

  • Introduce a standalone server that is dedicated to running a mammesk and it is a lot of stuff, with lots of RAM and hard disk apps < Li> Get all DB examples to feed the luggage memory server
  • Monitor memory usage from time to time to create scaling in the future by launching more cluster memcache to load.
  • Cash strategy and content can be used again in more than one webserver, who have the same style or data cache.

    If this design works, what kind of fallback or precautions have already been made? That is because I can not repeat the mistakes and learn from others.

    Thanks

    There is one thing to be careful about this design :

    What happens when the memcache server restarts (or failed) then you loose all your cache, the best case is that your site slows down during the rebuilding of the cache, the worst The situation is that your site does not have to rebuild the cache.

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

Oh, for the moment I am not sure how it is officially supported, but for the success of the people Using Monodroid Vic Cool Storage I am able to leave and compile assemblies in my project, but while trying to use some classes, the errors of time have to be gathered. Especially when trying to connect like the example for Mono Touch string dbName = path. Cobain (environment. Gatefolder path (environment specialfolder personal), "mydb.db3"); // The following line will be called coolestation, where is the database, // to make it if it does not exist, and call a delegate that creates the necessary tables (only when the database file was newly created //) CSConfig.SetDB (DbName, true, () => {CSDatabase.ExecuteNonQuery ("Subscriber Integer Primary Key Attribute, Name Text (50) No, Number, Date First Text (30)");); There is no difference when I try to use the methods of CSConfig and when I cscfif If I try to pass 3 aggregates to STDB (3) then I get the invalid ...

python - referencing a variable in another function? -

-
I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
