With this version, the beta phase of Elasticsearch Nodes ends. Elasticsearch Nodes now require a license to work. Please check our website to get more information and request a trial or paid license.

Add support for Elasticsearch 7.x releases. Existing nodes have been split by Elasticsearch major releases. Please use the appropriate nodes (e.g. Elasticsearch Reader (ES 6) for Elasticsearch 6.x or Elasticsearch Reader (ES 7) for Elasticsearch 7.x) according to your Elasticsearch cluster version. Going forward, we will align our support with the Elasticsearch Maintanance Policy. This basically means, our goal is to maintain the most recent minor release from the current major release stream and the most recent minor release from the prior major release stream.

Elasticsearch Console: Node now returns the complete JSON response instead of filtering out attributes.

Fixed some issues and typos in node descriptions.

Initial release of Elasticsearch Nodes for KNIME.

Elasticsearch Connector: New node to establish a connection to an Elasticsearch server or cluster. Specify protocol, host, port and authentication and test the connection. An Elasticsearch connection can be passed to other Elasticsearch Nodes and used for executing queries.
