Android - Couchbase attachments storage and selective pull replication

0
votes

I had the following 2 questions on couchbase on android:

  • When the couchdb is replicated to the android device, are the attachments in the document downloaded and saved to the SDCard or only the plain document(json) is saved?
  • is it possible to perform selective replication. Basically if a couchdb contains a chunk of documents, Can I replicate only a subset of the documents? I am using the Ektorp Client library.

Update : For the second question the answer by "I dropped out of a java school" is good. The right term is Filtered Replication.

I'm looking for an answer for the first question with evidence.

Attachments are fully transferred during replication

You can filter the replication based on the contents of the document with a filter function, you can find more info - http://wiki.apache.org/couchdb/Replication#Filtered_Replication

You cannot replication 'parts' of a document, its all or nothing with the replicator

CouchDB's concept of replication includes the document, all revisions and all attachments for that document; the replicator makes document A look the same on System 1 as it does on System 2.

In short, your documents and their attachments will go from Android device to server and from server to Android device.
