This could add more possibilities that more operators can be merged > into multiple input operator. > Different batch, stream operators require the shuffle keys and the state keys > must be exactly the same, otherwise the state may be not correct. > We only support a few operators in this issue, such as Join and regular > Aggregate. Other operators will be supported in the future. -- This message was sent by Atlassian Jira (v8.3.4#803005)
