Hi, we are currently looking into HBase. Just what we would require is some kind kind of merging old and new values. One example would be an append: instead of table.put we like to have a table.merge(PUT, "append").
In traditional databases this behavior could be achieved by trigger functions. So here some questions: a) Does some way to do so already exist and we overlooked it (Yes, we might access old versions and "merge" at query time) b) Any ideas where to start implementing this kind of functionality? (overall idea: provide some merge user defined function which can be specidied at put/merge time) c) Is this interesting to other people as well? Thanks! JS
