---------------------------------
Summary: records deleted from CachingKeyValueStore still appear in
range and all queries
Key: KAFKA-4283
URL: https://issues.apache.org/jira/browse/KAFKA-4283
Project: Kafka
Issue Type: Bug
Components: streams
Affects Versions: 0.10.1.0
Reporter: Damian Guy
Assignee: Damian Guy
Fix For: 0.10.1.1
Records deleted from CachingKeyValueStore appear in range and all queries. The
deleted record is replaced with an LRUCacheEntry(null), so that when a flush
happens the deletion can be sent downstream and removed from the underlying
store.
As this is valid and needed, the iterator used when querying a cached store
needs to be aware of the entries where LRUCacheEntry.value == null and skip
over them
