TL;DR: Look at the project on Github.
During my last interactions with the Couchbase community, I had the question how can I easily import my data from my current database into Couchbase. And my answer was always the same:
Take an ETL such as Talend to do it
Just write a (more...)
Already 6 months! Already 6 months that I have joined Couchbase as Technical Evangelist. This is a good opportunity to take some time to look back.
So first of all what is a Developer/Technical Evangelist?
Hmm it depends of each company/product, but let me tell you what it is for (more...)
I have created this simple screencast to show how you can, using Couchbase do some realtime analysis based on Twitter feed.

At last week’s Dallas Oracle Users Group meeting

Back in March 2012 I experienced an air milage overflow: almost straight from Madrid I’ve picked a flight to Israel to speak at a Big Data conference, only to be back in Lisbon and fly again to Johannesburg in South Africa to meet several customers in the retail and manufacturing area.
