1. Scaling MongoDB dengan ReplicaSet dan
Sharding
Download paper: http://de.tk/UKbjC

2. Application Design
● Strategi penambahan server
● Strategi mendistribusikan request
● Strategi pengembangan database
● Strategi penanganan static file
● Strategi penanganan session
● dst

3. Success Story
● Facebook
● Twitter
● Dll
Tidak selalu bisa diimplementasikan dengan mudah

4. Scaling Database
● Konsistensi data
● Cara mendistribusikan data
● Cara menangani id unik
● Strategi failover
Salah satu kunci utama, tapi yang paling sulit
dilakukan, karena:

5. Application Evolution
Tahap 1: Semua service dalam satu server

6. Tahap 2: Pemisahan aplikasi dan database

7. Tahap 3: Penambahan Webserver

8. Tahap 4: Penambahan Cache Service

9. Tahap 5: Database Master-slave

10. Tahap 6: Database Master-master

11. Tahap 7: Database Partitioning

12. Kriteria scaling database
● Automatc failover
● Symmetric
● Konfigurasi minimum dari sisi client
● Write-scalable

13. Feture ReplicaSet dan Shariding MongoDB yang
memenuhi kriteria ini.

14. ReplicaSet
Dikutip dari docs.MongoDB.org:"A MongoDB
replica set is a cluster of mongod instances that
replicate amongst one another and ensure
automated failover. Most replica sets consists of
two or more mongod instances with at most one
of these designated as the primary and the rest
as secondary members. Clients direct all writes
to the primary, while the secondary members
replicate from the primary asynchronously".

15. ReplicaSet

16. Setup ReplicaSet
> mongod --replSet myReplicaSet
> mongo 192.168.1.1:27017
> rs.initiate();
> rs.add('192.168.1.2:27017');
> rs.add('192.168.1.3:27017');

17. Implementasi ReplicaSet di PHP
$mongo = new MongoClient('92.168.1.1');
$mongo = new
MongoClient('92.168.1.1,92.168.1.2,92.168.1.3',
array('replicaSet' => 'myReplicaSet'));

18. ReadPreference
$mongo-
>setReadPreference(MongoClient::RP_SECO
NDARY_PREFERRED);

19. Sharding

20. Setup Sharding
> mongod --configsvr --dbpath /tmp/mongoconfig --port 27019
> mongos --configdb mongoconfig1,mongoconfig2,mongoconfig3
> mongo
> sh.addShard( "myReplicaSet/mongod1:27017" )
> sh.addShard( "myReplicaSet2/mongod2:27017" )
> sh.enableSharding("DBBlog")
> sh.shardCollection("DBBlog.posts", {"post_id" : 1})
