Filtered PullReplication on a channel

Mobile

Hi Folks,

I have android LITE with below pull setup.

Replication pullReplication = database.createPullReplication(syncUrl);
pullReplication.setContinuous(true);
Authenticator auth = new BasicAuthenticator(user, “password”);
pullReplication.setAuthenticator(auth);
userChannel = Arrays.asList(“user1”);
pullReplication.setChannels(userChannel);
pullReplication.setFilter(“designdoc/itemFilter”);
Map<String, Object> params = new HashMap<String, Object>();
params.put(“searchid”, “item”);
pullReplication.setFilterParams(params);
pullReplication.start();
pullReplication.addChangeListener(this);

How do i deal with filters if i am using couchbase server.?

Channel and filter can work together?

Basically I want to pull some filtered docs which belongs to a channel.

Have created views and done some emit http://docs.couchbase.com/admin/admin/UI/ui-views-editor.html.

Is the the way the filters work if i am not using couchDB?if so how to set filters in lite.

Something similar to https://github.com/couchbase/couchbase-lite-android/issues/200

Little puzzled help me out.

Thanks
Ntihin

Sync Gateway doesn’t support arbitrary filters, only filtering by channel.

Ok…Why does it not supported at SyncGateway?

Is setDocIds applicable for PULL, can i use this for filtered pull based on docids??

Thanks

Some compatible servers (CouchDB) support arbitrary server-side filters. SG uses channels instead, because they’re much more scalable.

SG also doesn’t yet support syncing with a list of docIDs. (Github issue)

@jens @hideki DocIds based fetch is possible now in CBL android from SyncGateway?

Sorry, I forgot it had been implemented for 1.2. Yes, it should now work.
