Sure, according to this [article](https://cwiki.apache.org/confluence/display/FLINK/FLIP-91%3A+Support+SQL+Gateway), the session in Flink SQL Gateway was designed for acting as an isolation of resources including metadata. And it support `USE CATALOG` commend to change different catalog. In addition, each session has its own `SessionState`, and the catalog infomation was saved in the [SessionState](https://github.com/apache/flink/blob/master/flink-table/flink-sql-gateway/src/main/java/org/apache/flink/table/gateway/service/context/SessionContext.java) -- This is an automated message from the Apache Git Service.
