12. Sync, multi platforms Solutions
13. Solution : Couchbase If you find that you’re building a “sync engine” to sync data from your app to other instances of your app and/or the cloud, then you should probably be building it on top of Couchbase Lite instead of going down that rabbit hole — since you may never make it back out.
14. Couchbase mobile history 1.0.0 1.0.1 1.0.2 1.0.3 1.0.4 1.1 May Jun Jul Aug Sep Oct Nov Dec Jan Feb Mar Apr May 2014 2015 Coubase Lite IOS Android OS X Linux Windows Sync Gateway Sync Authentication Read/Write Access Rest Coubase Lite .Net Xamarin Mono Coubase Lite Forest DB (alpha) Coubase Lite Unity (Beta) Coubase Lite Unity Sync Gateway Web Hooks View Query
15. Couchbase Mobile Couchbase Lite Couchbase sync Gateway Couchbase Server
16. Couchbase Mobile
17.  Open Source  Document oriented NoSql Databe  Schema less  Versionning  Connectors (spark, hadoop…) Couchbase Server
18.  Link between couchbase Server and Couchbase Lite  http Protocol – Lots of clients  Access management  Authentication (facebook, persona, custom…)  Authorization  Sync function (require user, roles, channels)  Easy to deploy  Written in Go – works on all Couchbase Server platforms  Test Database (Walrus) Couchbase Sync gateway
19. Custom Auth 1 3 2 4 Auth Server
20.  NoSql Database  Json Documents  Views and Queries  Robust – Uses sql lite (part of the system)  Lightweight (less than 500kb library size)  Native Api – Multi platforms  Multi architectures Coubase Lite
21. Star
22. Cluster
23. Peer 2 Peer
24. Native Api  Manager  Database  Document  Revision  Query / View  Channel / Role  Attachement  Model (IOS only)  Replication
25. « A Replication object represents a replication (or "sync") task that transfers changes between a local database and a remote one » Replication ?
26.  Push, Pull  One-shot vs Continuous  Filtered  Peer to Peer (bluethooth, wifi…)  Conflict management Replication in Couchbase
27. “Conflicts are not an error condition, they are the result of your infrastructure allowing the same data set to be modified across disconnected systems. The introduction of such conflicts in such a topology is the expected behaviour and their programmatic resolution is a core piece of application logic.” Conflicts
28.  revision : {%counter%-%hash%}  Same change on different devices produce the same hash -> no conflict  Revision Tree Conflicts
29. Conflicts: Revision Trees 2-def 1-abc 1-abc 2-def 3-ghi 3-jkl
30. Conflicts: Revision Trees 2-def 1-abc 1-abc 2-def 3-ghi 3-jkl 3-ghi 3-jkl
31. Conflicts: Revision Trees 2-def 1-abc 1-abc 2-def 3-ghi 3-jkl 3-ghi 3-jkl
32. Conflicts: Revision Trees 2-def 1-abc 1-abc 2-def 3-ghi 3-jkl 3-ghi 3-jkl 2-def 3-ghi 1-abc 4-mn 4-mn 4-mn
33. Conflicts: Revision Trees 2-def 1-abc 1-abc 2-def 3-ghi 3-jkl 3-ghi 3-jkl 2-def 3-ghi 1-abc 4-mn 4-mn 4-mn
