--------------------------------
Summary: Remove commons-collections dependency from innodb
Key: CALCITE-5823
URL: https://issues.apache.org/jira/browse/CALCITE-5823
Project: Calcite
Issue Type: Improvement
Components: innodb-adapter
Affects Versions: 1.34.0
Reporter: Ran Tao
Assignee: Ran Tao
Fix For: 1.35.0
Currently, \{CollectionsUtils} is only used in a few places in the InnoDb
adapter, and the only methods used are \{isEmpty}} and \{isNotEmpty}.
The only difference between \{CollectionUtils.isEmpty} and \{list.isEmpty} is
the behavior if \{list} is null. Modern coding practices would ensure that
\{list} is not null unless specified in its type.
So we can safely remove it to avoid using an entire library just for the sake
of using \{isEmpty}.
