---------------------------------
Summary: Optime hive parallelism inference
Key: FLINK-24953
URL: https://issues.apache.org/jira/browse/FLINK-24953
Project: Flink
Issue Type: Improvement
Components: Connectors / Hive
Affects Versions: 1.14.0, 1.13.0
Reporter: xiangqiao
Currently, when I disable hive table source parallelism inference using
configuration and set parallelism.default: 100.
{code:java}
table.exec.hive.infer-source-parallelism: false
parallelism.default: 100{code}
The result is that the parallelism of hive table source is {*}1{*}, and the
configuration of the default parallelism is not effective.
I will optimize this problem. In the future, when disable hive table source
parallelism inference ，the parallelism of hive table source will be determined
according to the following order：
1. If table.exec.resource.default-parallelism is set, the configured value will
be used
2. If parallelism.default is set, the configured value is used
3. If the above two configuration items are not set, the default value is 1
