xiaoran created FLINK-33227: ------------------------------- Summary: Flink sql cep support 'notFollowedBy' semantics Key: FLINK-33227 URL: https://issues.apache.org/jira/browse/FLINK-33227 Project: Flink Issue Type: New Feature Components: Table SQL / API Affects Versions: 1.16.0 Reporter: xiaoran
Currently, the cep mode of the Flink API can support next, notNext, followedBy, followedByAny, and notFollowedBy semantics, but Flink SQL only supports next semantics. The remaining notNext and followedBy semantics are implemented by other alternatives, while the notFollowedBy semantics are not currently implemented. At present, this semantics is generally implemented in business scenarios, such as judging that a user has placed an order within 15 minutes without paying. Therefore, I want to provide new functionality to support notFollowedBy in sql mode, along with the other three semantics -- This message was sent by Atlassian Jira (v8.20.10#820010)
