24. Sync Gateway revision properties • MaxRevsCacheSize (default is 5000) • MaxRevTreeDepth (default is 20)
25. Sync Function • Channels • Users • Roles
28. name : hideki password : letmein name : pasin password : letmein name : jim password : letmein access(user_name, channel_names) channel(channel_name) role(role_name, channel_name) requireAccess(channel_name) requireRole(role_name) requireUser(user_name)
29. Sync Function • Read: access • Write: requireAccess, requireUser, requireRole • Grant a user access to multiple channels by simply assigning a role • Any user can give another user access to the Sync Function
30. name : hideki password : letmein name : pasin password : letmein name : jim password : letmein access(user_name, channel_names) channel(channel_name) role(role_name, channel_name) requireAccess(channel_name) requireRole(role_name) requireUser(user_name)
31. name : hideki password : letmein name : pasin password : letmein name : jim password : letmein channel(channel_name) role(role_name, channel_name)
32. Sync Function User 1 User 2 User 3 Channel X Channel Y Channel Z Channel X Channel Y Channel Z Channel X Channel Y
33. Sync Function User 1 User 2 User 3 Role Channel X Channel Y Channel Z

47. Enabling SSL • Enabling SSL • It’s important for your users data! • Sync Gateway config • Replicator config
48. WWDC 2015 "App Transport Security (ATS) lets an app add a declaration to its Info.plist file that specifies the domains with which it needs secure communication. ATS prevents accidental disclosure, provides secure default behaviour, and is easy to adopt. You should adopt ATS as soon as possible, regardless of whether you’re creating a new app or updating an existing one. If you’re developing a new app, you should use HTTPS exclusively. If you have an existing app, you should use HTTPS as much as you can right now, and create a plan for migrating the rest of your app as soon as possible."
49. WWDC 2015 TL;DR: If you run your own API server, FIX YOUR SSL
50. Sync Gateway Android iOS {
 "SSLCert": "/path/to/cert.pem",
 "SSLKey": "/path/to/privkey.pem",
 "databases": {
 "db": {
 "server": "walrus:"
 }
 }
 } sync-gateway-config.json Application.java AppDelegate.swift private static final String SYNC_URL = "https://10.10.106.24:4984/db/"; Replication pull = database.createPullReplication(SYNC_URL);
 pull.setContinuous(true); 
 pull.start(); let SYNC_URL = "https://10.10.106.24:4984/db/" let pull = database.createPullReplication(SYNC_URL) pull.continuous = true pull.start()
51. Self signed certificates $ openssl genrsa -out privkey.pem 2048 $ openssl req -new -x509 -key privkey.pem -out cert.pem -days 1095 Source: https://www.openssl.org/docs/HOWTO/certificates.txt
52. SSL • SSL support to the listener server • SSL client cert auth support

62. Restarting Sync Gateway 1.Setup repo for your Sync Gateway Config 2.Setup Circle CI with the GitHub repo 3.Run the container with the new config: $ gulp production $ docker run -d -p 4984:4984 \ -p 4985:4985 \ couchbase/sync-gateway \ ./dist/sync_gateway_config.json 4.Resync the database: $ curl -vX POST -H 'Content-Type: application/json' \ :4985/db/_resync/
