Yangze Guo created FLINK-26675: ---------------------------------- Summary: Parallelized heavy serialization operations in StreamingJobGraphGenerator Key: FLINK-26675 URL: https://issues.apache.org/jira/browse/FLINK-26675 Project: Flink Issue Type: Sub-task Components: Client / Job Submission Reporter: Yangze Guo Assignee: Yangze Guo Fix For: 1.16.0
For some complex jobs, the compilation time of the job graph may exceed one second, which is unaffordable for short queries in the OLAP scenario. After a deeper investigation, we found that the hot path is the serialization of `OperatorCoordinator` and `StreamOperatorFactory`. We proposed to parallelized these heavy serialization operations to accelerate the compilation of job graphs. -- This message was sent by Atlassian Jira (v8.20.1#820001)
