---------------------------------
Summary: Close KeyValueIterator implemented instance to avoid
resource leak
Key: KAFKA-13122
URL: https://issues.apache.org/jira/browse/KAFKA-13122
Project: Kafka
Issue Type: Bug
Components: streams
Reporter: Luke Chen
Assignee: Luke Chen
Found there are "many" KeyValueIterator implemented instances don't explicitly
get closed, which will cause resource leak. This issue mostly happen in tests
because we usually query state store to get result iterator, and then do
verification, but forgot close it. This issue also appear in the example code
in our developer guide docs.
