 may indeed be able to solve this problem, but I feel that it is more biased 
towards catalog storage problems. If sql-gateway can support a " -i, --init 
<initialization file>" parameter similar to sql-client or support a similar 
"sql-gateway-defaults.yaml" configuration file similar to 
[ververica-flink-sql-gateway|https://github.com/ververica/flink-sql-gateway/blob/master/conf]
 can solve this problem very well. Because it is not just catalogs, it may also 
involve some udf initialization and so on.

> Gateway supports initialization of catalog at startup
