how we can do that?or how to speedup Drupal

server sideinstall Varnish for caching pages for anonymous users.install a persistent cache system (Memcached, APC, Memcache).use a CDN such as Akamai to serve static files (JavaScript, CSS, images).

how to speedup drupal - code side

use Pressflow, it allows Varnish to serve cached page for anonymous users.clean Drupal's watchdog table. Every time a watchdog error gets logged, it consumes CPU resources on the web server and database server. It also increases load time significantly.implement static and persistent cache strategies until the slow query log comes up clean.avoid PHP errors that occur within nested foreach loops at all costs.uninstall unused modules.turn on caching for Drupal core blocks and Views.

how to speedup drupal - database side

Drupal sites live or die by their database.make sure the tables are properly indexed for faster searching.do not store unnecessary records, a 100 node database will be always accessed faster than a 3 million node database.change how/where you store your data

Now we’re screwed

shift of technologies - db solutions

from well-established relational databases to NoSQL technologies.NoSQL was first introduced as concept in 1998, it really wasn’t until 2009 that it emerged as a real trend.NoSQL solutions aren't replacements traditional solutions, but rather address a specific need in addition to what one might get from traditional offerings. In 90% of the time you’ll probably implement a hybrid system.put simply, NoSQL is about being open and aware of alternative, existing and additional patterns and tools for managing your data.

shift is happening nowfew years ago (and still now) MySQL was the undisputed king of the open-source database hill.It is still growing with great speed (40% compound annual grow rate)

butThere are some competitors that are emerging and grow even faster.

"NoSQL database technologies are largely being adopted for new projects that require additional scalability, performance, relaxed consistency and agility."

other features of MongoDBDocument-based queries

Flexible document queries expressed in JSON/Javascript.Map Reduce

Flexible aggregation and data processing.Queries run in parallel on all shards.

JSON-style documents with dynamic schemas offer simplicity and power.

Full index support (+geo)Index on any attribute, just like you're used to.

Replication and High AvailabilityMirror across LANs and WANs for scale and peace of mind.

6 mongoDB conceptsMongoDB has the same concept of a 'database' with which you are likely already familiar (or a schema for you Oracle folks). Within a MongoDB instance you can have zero or more databases, each acting as high-level containers for everything else.A database can have zero or more 'collections'. A collection shares enough in common with a traditional 'table' that you can safely think of the two as the same thing.Collections are made up of zero or more 'documents'. Again, a document can safely be thought of as a 'row'.

6 mongoDB conceptsA document is made up of one or more 'fields', which you can probably guess are a lot like 'columns'.'Indexes' in MongoDB function much like their RDBMS counterparts.'Cursors' are different than the other five concepts but they are important enough, and often overlooked, that I think they are worthy of their own discussion. The important thing to understand about cursors is that when you ask MongoDB for data, it returns a cursor, which we can do things to, such as counting or skipping ahead, without actually pulling down data.

basic mongo commandsdb.help() -- also db.help (no parentheses)show dbs -- show databasesuse -- for selecting databasedb.getCollectionNames()Since collections are schema-less, we don't explicitly need to create them. We can simply insert a document into a new collection. To do so, use the insert command, supplying it with the document to insert.

Drupal & mongoIn Drupal 7 if you use field API you want your fields inside mongodb. If you store them inside sql you cannot query them efficiently.Storing data into SQL will crete cases where you will run into denormalization issues, and with mongo that will be solved.In Drupal 7 everything is entity; nodes are entity, users are entity, comments are entity.We only need few system tables in MySQL that are hard-wired with core drupal; but those things are cached (memcache) everything else can go to mongo. and they (mongo & memcache) are easy to scale.

mongoDB module

EntityFieldQuery Views Backend

http://drupal.org/project/efq_viewsThis module enables Views to use EntityFieldQuery as the query backend, allowing you to query all defined entity types and their fields, even the ones stored in non-sql storage such as mongodb.

http://drupal.org/project/efq_views




Load into nodes into mongo<?php// Connect$mongo = new Mongo();

// Get the database (it is created automatically)$db = $mongo->testDatabase;

// Get the collection for nodes (it is created automatically)$collection = $db->nodes;

// Get a listing of all of the node IDs$r = db_query('SELECT nid FROM {node}');

// Loop through all of the nodes...

foreach($r as $row) { print "Writing node $row->nid\n";

// Load each node and convert it to an array. $node = (array)node_load($row->nid);

// Store the node in MongoDB $collection->save($node);

}?>

code sample# drush php-script mongoimport.php

# use testDatabase;# db.nodes.find( {title: /Distineo/i} , {title: true}).limit(4);

code sample# drush php-script mongoimport.php

# use testDatabase;# db.nodes.find( {title: /Distineo/i} , {title: true}).limit(4);

// how to use mongo in php code<?php// Connect$mongo = new Mongo();

// Write our search filter (same as shell example above)$filter = array( 'title' => new MongoRegex('/Distineo/i'),);

// Run the query, getting only 5 results.$res = $mongo->testDatabase->nodes->find($filter)->limit(5);

// Loop through and print the title of each article.foreach ($res as $row) { print $row['title'] . PHP_EOL;}?>

Where mongo won’t work

Joining across Entitiesex. return birthday from profile belonging to author of current node
