This enables you to manage and transform your data between Couchbase Server and other data stores in your enterprise.

The connector consists of two components: 1. tCouchbaseInput, the input component, takes

incoming data streams, transforms them into JSON documents, and stores them in Couchbase

2. tCouchbaseOutput, the output component, transforms JSON documents into target data formats and stores in target system

Tutorial Errata for Talend 5.6

Couchbase server version 2.0 hard-coded in Talend component panel (it works )
