+# Contributing to Trino-Rabbitmq-Event-Listener
+
+## Rules
+
+- In addition to creating pull requests, ideas and feature pushes are encouraged in the issues tab
+- Use feature branches. **Create an issue for every single feature or bug** and **label** it. If you are a core contributor, create a branch named gopipeline/[issue #] to resolve the issue. If you are not a core contributor, fork and branch.
+- Try to label issues and PRs as accurately as possible, especially in the case of PRs, where `semver-major`, `semver-minor` and `semver-patch` labels are available. Labels on issues should be a subset of the labels on the corresponding pull request; the milestones should match.
+- Use github "Fixes #[issue]" syntax on your PRs to indicate which issues you are attempting to resolve
+- Where possible, avoid adding extra dependencies to the project
+
+## Sign-off your Commits
+
+We encourage contributors to "sign-off" on their commits:

+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.

+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,

+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+# Trino Rabbitmq Event Listener
+
+Event listener plugin for Trino to send query and split events to rabbitmq. 
+
+Features:
+- specify which events can be published
+- configure exchange and exchange types
+- publish events to mutliple queues
+- specify payload construction before queue publication
+- append custom properties to be sent along with the event payload
+
+## Building
+
+```bash
+./build.sh
+```
+
+Then copy the generated jar file into your Trino plugins directory
+
+## Registering
+
+Add `event-listener.properties` with the structure
+
+```properties
+event-listener.name=rabbitmq
+server-url=amqp://<server-url>
+exchange-name=<exchange-name>
+exchange-type=<exchange-type>
+durable-exchange=<true|false>
+publish-query-created=<true|false>
+query-created-queues=<separated-list>
+publish-query-completed=<true|false>
+query-completed-queues=<separated-list>
+publish-split-completed=<true|false>
+split-completed-queues=<separated-list>
+payload-parent-keys=<key1>.<key2>...
+x-custom-<key_string1>=<value1>
+x-custom-<key_string2>=<value2>
+...
+x-custom-<key_stringN>=<valueN>
+```
+
+# Parent nesting key & payload publication
+
+The payload will be published on the queue like
+
+```json
+{
+  "<payload-parent-key1>": {
+    "<payload-parent-key2>": {
+      "<trino-field1>": "...",
+      "<trino-field2>": "..."
+    },
+    "x-custom-<key_string1>": "<value1>",
+    "x-custom-<key_stringN>": "<valueN>"
+  }
+}
+```
+
+The parent keys will determine where the payload is nested inside. 
+The custom properties will live as a sibling field to the payload
