------------------------------------
Summary: Performance problems encountered when using
StatementSetImpl#addInsertSql in Flink SQL
Key: FLINK-29312
URL: https://issues.apache.org/jira/browse/FLINK-29312
Project: Flink
Issue Type: Improvement
Components: Table SQL / API
Affects Versions: 1.14.2, 1.13.5
Reporter: shouzuo meng
It is necessary to use insert in batches in a flink sql task. Through testing,
it is found that when two insert statements are inserted using
StatementSetImpl#addInsertSql, the resource usage is good. When there are more
than two, using StatementSetImpl#addInsertSql will consume more resources.
The above resource usage statistics are based on the same environment, using
StatementSetImpl#addInsertSql to compare the running situation when it is
divided into multiple tasks according to the number of inserts. When there are
more than two insert statements, the latter will use less resource.
