Fabian Hueske created FLINK-3835: ------------------------------------ Summary: JSON execution plan not helpful to debug plans with KeySelectors Key: FLINK-3835 URL: https://issues.apache.org/jira/browse/FLINK-3835 Project: Flink Issue Type: Bug Components: Optimizer Affects Versions: 1.0.2, 1.1.0 Reporter: Fabian Hueske Assignee: Fabian Hueske Fix For: 1.1.0, 1.0.3
The JSON execution plans are not helpful when debugging plans that include join operators with key selectors. For joins with hash join strategy, the driver strategy shows: {{"Hybrid Hash (build: Key Extractor)"}} where {{(build: Key Extractor)}} shall help to identify the build side of the join. However, if both inputs use KeySelectors, the build side cannot be identified. I propose to add the operator id to the build side information. The same issue applied for cross driver strategies. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
