Description

Apache Paimon is a lake format that enables building a Realtime Lakehouse Architecture. After it gradulates, it becomes the Apache top level project. I want to introduce Apache Paimon as a
Connector of Trino, just like Iceberg or Hudi connector. Please give me some advice, thank you~

Paimon website: https://paimon.apache.org/
Paimon github home page: https://github.com/apache/paimon

Supported: read from Paimon, write to Paimon.

Thank you for your pull request and welcome to our community. We could not parse the GitHub identity of the following contributors: 仟弋.
This is most likely caused by a git client misconfiguration; please make sure to:

  1. check if your git client is configured with an email to sign commits git config --list | grep email
  2. If not, set it up using git config --global user.email [email protected]
  3. Make sure that the git commit email is configured in your GitHub account settings, see https://github.com/settings/emails
