On behalf of the PMC I am delighted to announce Christian Beikov as a new Calcite committer.
Christian’s first contribution[1] — quite out the blue — was a new adapter for Elasticsearch5. Since then he has made various improvement’s to Calcite’s support for federation and materialization, and has been active in design discussions and helping users on the dev list. Please give Christian a warm welcome to the project! Julian [1] https://github.com/apache/calcite/commits/master?author=beikov <https://github.com/apache/calcite/commits/master?author=beikov>
