Is anyone aware of Knime nodes for interfacing with ElasticSearch? I have created a basic custom extension node which writes to ElasticSearch, but it only handles basic columns types (numeric, string, and dates). I would be interested in one with better handling of collection columns and from a real ElasticSearch API expert. Any pointers?
We have several nodes which are currently not (yet?) publicly available though. Probably get in touch with @danielesser to check details.
