EronWright opened a new pull request #7393: [FLINK-9172][table][sql-client] - Support external catalogs in SQL-Client
URL: https://github.com/apache/flink/pull/7393
 
 
   ## What is the purpose of the change
   
   _Based on #7392.  Please see commits prefixed with FLINK-9172._
   
   Adds support for catalogs to the SQL Client environment file, using descriptors.  For example, here's a sample catalog of type `taxi-data` being registered into `sql-client-defaults.yaml`:
   ```
   catalogs:
     - name: nyc
       type: taxi-data
       rides-file: /Users/david/stuff/flink-training/trainingData/nycTaxiRides.gz
       fares-file: /Users/david/stuff/flink-training/trainingData/nycTaxiFares.gz
   ```
