Kurt Young created FLINK-14672: ---------------------------------- Summary: Make Executor stateful in sql client Key: FLINK-14672 URL: https://issues.apache.org/jira/browse/FLINK-14672 Project: Flink Issue Type: Improvement Components: Table SQL / Client Reporter: Kurt Young
Currently sql client is stateless, it read config files into `Environment` and recorded all session changes into `SessionContext`. Each time sql client want to execute a new command, we have to first construct `ExecutionContext` by combining `Environment` and `SessionContext`, and then transfer all information into a new `EnvironmentInstance`. It works well before but kind of hard to extend now. One example is support creating table in sql client. We have to remember create statements and replay them every time we want to execute a new command. If we can make sql client stateful, and table environment be the state of sql client, things will be much more easier. This Jira should revisit all related classes, and define a clean relationship between old roles after making sql client stateful. -- This message was sent by Atlassian Jira (v8.3.4#803005)
